Certain plant combinations can repel pests, attract beneficial insects, and enhance soil health, leading to a more productive and resilient garden. Techniques like interplanting, polyculture, and guild planting can help maximize space and create diverse, self-sustaining plant communities. Interplanting is a method of planting certain crops together to increase growing space in the garden. Garlic, known for its pungent smell, can be used as a companion plant or as a pesticide when used as a pesticide.
Garlic (Allium sativum) is famous for its pungent smell, which acts as a deterrent to keep bugs away from the garlic plant. Additionally, there is evidence that when used as a companion plant, garlic can also help reduce pest issues, soil health issues, and increase crop yield.
Intercropping is a valuable tool in agriculture, where different crops are planted in the same area at the same time to improve yields and benefit each other’s ecosystems. Using a “trap crop” to divert pests is another effective method of growing. Plants used as trap crops should be planted earlier than the main crops.
Company planting is an excellent way to reduce pest issues, soil health issues, and increase crop yield. Mixed plant communities are more resilient, as mixtures of plants similar to those found in nature are less susceptible to disease outbreaks and damaging insects. Planting a greater number of different plants together can provide greater resistance to severe outbreaks.
Company planting nurtures a balanced environment and keeps many invasive pest populations in check, allowing us to avoid chemical pest control. Some examples of companion plants that can effectively repel various sucking pests, worms, and moths include chrysanthemum, marigold, mint, and lemon. Other companion plants do attract pest insects but will distract them away from your fruit and vegetable plants instead.

What Do Professionals Use For Pest Control?
Pest control companies employ various insecticides such as pyrethrins, permethrin, and bifenthrin to effectively target spiders and spider mites, disrupting their nervous systems and leading to paralysis or death. In addition to chemical treatments, physical barriers like sticky traps help prevent spider infestations. Common pest control chemicals include insecticides for insects and rodenticides for rodents. Professional pest control requires in-depth knowledge of pest behavior, effective control strategies, and adherence to regulations.
For significant pest issues, professionals often use chemical pest control products, with special attention to the safe application to protect pets and children. It’s vital to understand the active ingredients in pesticides, like pyrethroids and hydramethylnon, along with their risks and alternative methods. The choice of methods varies according to the pest type, regional conditions, and severity of the infestation.
In this comprehensive guide, readers can learn about the strategies and products that pest control professionals utilize, revealing their selections based on effectiveness against various pests. Additional tools, including personal protective equipment and bait stations, are integral to pest control efforts. Understanding the chemicals used, their potential hazards, and proper safety precautions enables homeowners to make informed decisions regarding pest control services, ensuring effective and safe eradication of pests.
Does Intercropping Reduce Pests?
Numerous studies emphasize the advantages of diversification practices such as intercropping, particularly with pigeon pea and various crops, in minimizing pest damage (Srinivasa Rao et al. 2004; Songa et al. 2007). Intercropping enhances climate resilience through improved plant resource efficiency (including space, nutrients, and water) and the natural suppression of pests, pathogens, and weeds. Research indicates a reduction of 38% in pest abundance and 41% in density without affecting species richness.
By growing crops between main crops, intercropping lowers the risk of pest infestations, showing promise as an effective pest management strategy. Increased activity of natural pest enemies in intercrops can help control specific insect pests and at least one soil pathogen.
Furthermore, intercropping and incorporating crops that repel pests, attract natural enemies, or possess antibacterial properties can lessen disease and pest damage as well as pesticide use. It also disrupts pathogen spore dispersal and fosters a disease-suppressive environment (Zhu and Morel 2019). root exudates from intercrops may develop resistance to nematodes through various mechanisms.
Despite evident benefits for controlling weeds, pathogens, and insects—as well as improving yield and profitability—thorough understanding of how specific crop combinations and characteristics impact pest and beneficial arthropod behavior is critical. Ultimately, intercropping has substantial potential in pest and disease control under favorable conditions, enhancing beneficial insect populations while suppressing pests effectively.
How Do I Stop Bugs From Eating My Vegetables?
To naturally repel and manage pests in your vegetable garden, start by mixing dish soap with water in a spray bottle (a few squirts of soap and the rest filled with water). This solution can be sprayed on plants from top to bottom to help eliminate and deter bugs, with reapplication after heavy rain. Recognizing common garden pests early on is vital for effective control. While it’s impossible to protect plants entirely from nature, there are measures to reduce insect presence and safeguard your crops.
Consider crop rotation and planting pest-resistant varieties. An effective insecticide combines soap and vegetable oil, disrupting bugs' breathing and digestion. Beneficial insects can also assist in pest management. Various non-toxic repellents are available, including those with garlic or hot-pepper oil, which deter bugs. Vinegar can serve as both a natural bug repellent and weed killer when mixed appropriately. Daily misting with a simple dish soap solution can keep bugs in check.
Neem oil is an especially potent organic pesticide and can be applied with soap and water. Lastly, barriers like insect mesh and horticultural fleece can effectively separate pests from plants, while companion planting with marigolds and alliums can provide additional protection against destructive insects.
What Is The Best Defense Against Pests?
To effectively prevent pests, prioritize pest prevention strategies. Begin by eliminating sources of food, water, and shelter—store food in airtight containers and repair leaky plumbing to avoid water accumulation. Reducing clutter will limit hiding and breeding spaces for pests. Dispose of trash daily, keeping large bins outside or in the garage to deter pest entry. After implementing these preventive measures, consider insecticide perimeter treatments as a first line of defense.
Ensure you use reliable pest information, as not all sources are trustworthy. To maintain a pest-free environment, regularly sweep and mop, address leaking pipes, and eliminate stagnant water. Sealing entry points with high-quality door sweeps and using expanding foam can further fortify your defenses. Incorporate physical pest control methods like traps, chemical options like pesticides, and biological controls where appropriate. Additionally, ensure good soil and healthy plants for gardening.
Your integrated pest management (IPM) program should focus on sanitation and maintaining a clean, organized home. By following these actionable steps, you can create a clean, safe space free from pest infestations and bolster your defenses against future incursions.
What Do You Plant With Vegetables To Keep Bugs Away?
Garlic and several aromatic herbs like Lavender, Rosemary, and Sage are excellent for pest control in gardens, repelling common pests such as spider mites, aphids, and Japanese beetles. These herbs, when allowed to flower, also attract beneficial insects that assist in pollination. Additionally, Marigolds help deter aphids and mosquitoes while being small enough to integrate easily among other plants. Rue is effective for attracting ladybugs near roses, which consume aphids.
Companion planting is a key strategy for repelling pests naturally and confusing their sense of smell. For instance, Calendula and Chamomile are effective: Calendula deters pests with bright flowers, while Chamomile attracts beneficial insects. Incorporating flowers and herbs with vegetables can create a habitat for good insects, such as ladybugs and lacewings, that prey on harmful bugs. Planting basil next to tomatoes helps repel pests like whiteflies and the tomato hornworm, while Nasturtiums lure aphids away from other plants.
Other herbs like Mint, Oregano, and Thyme are also effective, with Mint deterring spiders and ants. However, caution is needed with Mint as it can rapidly spread. Overall, integrating these plants supports both the health of your garden and sustainable pest control without resorting to chemicals.
What Pests Do Nasturtiums Repel?
Nasturtium (Tropaeolum spp.) is an effective pest-repellent plant that helps safeguard garden vegetables by producing airborne chemicals that deter harmful insects such as whiteflies, squash bugs, aphids, cabbage loopers, and some beetles. This plant's spicy scent may also keep mosquitoes at bay. Interestingly, while nasturtiums repel many pests, they can also attract certain insects, enabling their use as a trap crop to draw pests away from more desirable plants.
When grown alongside crops like cucumbers and tomatoes, nasturtiums assist in repelling cucumber beetles and other pests. They can be strategically paired with eggplant and squash to further enhance pest control.
Aphids, known for their preference for cool, wet conditions, are a common target for nasturtiums, making these plants invaluable in protecting vulnerable crops. The plants also attract beneficial insects like ladybugs and hoverflies, which further contribute to pest control in the garden. Studies indicate that nasturtiums effectively discourage pest damage by acting as a trap crop, drawing harmful insects away from crops.
In summary, nasturtiums serve as both a protective companion plant and a trap for garden pests, making them an excellent choice for organic pest management and vibrant garden aesthetics.
What Plant Works As A Natural Pest Control?
Herbs and flowers can serve as effective natural pest protectors in your garden. Numerous plants are not only visually appealing but also act as deterrents against harmful insects. For instance, petunias, garlic, and basil are excellent companions for tomato and broccoli plants. Oregano and dill enhance the health of cucumbers while keeping pests at bay. These plants provide a sustainable and non-toxic alternative to conventional pesticides.
Citronella is renowned for its pest-repelling qualities, while marigolds emit a unique scent that drives away flies, gnats, and mosquitoes. Lavender and mint are additional powerful repellents, with their aromas effectively keeping unwanted insects at a distance. Herbs like cilantro not only attract beneficial insects but also contribute to pest management. Strongly scented herbs, including chives and sage, repel a variety of pests, ensuring a healthier garden.
Incorporating these varieties increases both the beauty and biodiversity of your garden while reducing the need for harmful chemicals. To maximize their potential, consider planting herbs like fennel, yarrow, and borage, which support pest predator populations. Overall, natural pest protection through plants enhances your gardening experience by fostering a sustainable environment.
What Are The Risks Of Intercropping?
Intercropping involves cultivating two or more crops together, but it faces challenges like competition for water, light, and nutrients, potentially leading to lower yields. It struggles to fit into highly mechanized farming systems or when crops have differing input needs. This review examines intercropping’s impact on natural pest control services and crop productivity amidst climate uncertainty while highlighting its benefits and the risks that deter farmers from its adoption. Leguminous crops, when intercropped with non-leguminous ones, add nitrogen to the soil via rhizobium bacteria, benefiting both plants. Non-leguminous crops also enhance soil organic matter.
Documented benefits of intercropping include reduced pest infestation through host plant disruption and improved resilience against climate stressors. Although largely practiced by smallholder farmers to improve productivity and mitigate risks from crop failures and market fluctuations, intercropping is underutilized due to perceived complexities and risks, like lower yield and increased management difficulty.
Research shows that intercropped systems can achieve grain yields up to 22% higher than monocultures. Furthermore, intercropping helps in spreading crop failure risk over different crops with varying growth periods, contributing to food security in the face of climate change.
Despite its advantages, obstacles such as increased pest susceptibility, learning curves for successful management, and concerns about decreased yields hinder wider adoption. Nevertheless, intercropping can work as an insurance strategy in poor conditions, ensuring that at least one crop may thrive, thus improving overall agricultural sustainability.
Do Ultrasonic Pest Repellers Work?
In summary, ultrasonic pest repellers emit high-frequency sounds, ostensibly to reduce pest infestations, but studies indicate their ineffectiveness, contravening FTC guidelines. These devices primarily function by emitting sound waves above 20 kilohertz, which are inaudible to humans. While marketed as non-toxic alternatives to chemical insecticides, their efficacy varies by pest type and environment. Scientific analyses have shown that most ultrasonic repellers do not impact household pests significantly.
Although some users report temporary success, experts emphasize that these devices should not be solely relied upon for pest control, particularly in severe infestations, as they fail to address root causes. Overall, the consensus among professionals is that ultrasonic pest repellers are unreliable for long-term pest management, with no robust scientific evidence verifying their effectiveness. Homeowners have experienced mixed results, often finding that while there may be an initial effect, it dissipates over time, leading to skepticism regarding the true efficacy of these devices in combating pests.
📹 Unleash the Power of Companion Planting: Boost Your Yields and Deter Pests!
Are you tired of dealing with pests and struggling to get a good yield from your garden? It’s time to unleash the power of …
Well, being a farmer gardener I have to say, it sure does. I have been using this ancient old system for years and virtually never have to spray with pesticides, pollinate flowers,,,just harvest and eat fresh. Never looking back now,,my favorite combination is Tomato, Parsley and Sweet Basil surronded by Giant African Marigolds! Happy Gardening Marty & Karin
Thank you for sharing your garden and knowledge with us. I’m a YouTube gardener too. It’s my 3rd year and ever year I try to get better. This year I’m trying intercropping/companion planting. I found your website in my research. This is very helpful and I and so happy I found your website because it has so much to offer. I hope we can learn more from each other as we grow our gardens and our websites!
There are 2 issues here. Does companion planting work? And does companion planting marigolds work? Marigolds are one species and can not be thought of as the only companion plant. They will help with some things, and not so much others. Other species I have used include basil, oregano, buckwheat, clover, purslane, borage, sunflowers, tarragon, mint, lima beans, pole beans, nasturtiums and on and on. Some of these are not appropriate for some crops and are appropriate for others. You have to think through all the combinations. For example, oregano or a short clover work well with peppers as a ground cover. Nasturtiums are good in the zucchini. The 3 sisters method certainly works and is time tested. Basil does wonders for tomatoes as well as marigolds. Do you grow in a place that tomatoes and peppers need shade cloth? Giant sunflowers can certainly provide shade…just not too many.The trick is to have multi species companions and not just rely on marigolds only. You also need to think about what is happening underground as well. The roots of purslane help corn penetrate hardpan layers. So if you have hard pan, it can help. If you don’t have hardpan, then they probably won’t be a help. Here is a couple good references. First a cutting edge companion crop/multi-species cover crop vid. youtube.com/watch?v=9yPjoh9YJMk Next basil as a companion plant orgprints.org/6614/ There is a lot more information on my youtube page.
I don’t know about harming, But by pure chance we planted an heirloom Marigold mix one of the housemates picked up and placed the pots with my potted tomatoes just to beautify things up a bit. It was only after I noticed the lack of expected pests that I stumbled onto how marigolds can be helpful in that respect. I only had to deal with one pest really, I did find a few horn-worms on my plants which I pulled off and put off the property. I harvested the seeds from the best plants of those marigolds and they’ll go right back in my garden next year, whether tey really help or not. I just like the way they look.
Stephen, I’m planting less Monoculture and more Polyculture. I don’t really think about what makes good companions, but more on orientation. What needs or will grow in the shade of others. I have noticed less disease or delayed and fewer pest with a Polyculture system. What are your thoughts or studies on polyculture.
It’s funny that you mentioned the paper with the cabbages, until this year I have always had marigolds planted with them, and haven’t had much of a problem with pests. I use the marigolds to keep the neighbourhood cats out of the bed once I have planted the rest, but this year I had built a nice frame with chicken wire covering it to go over the bed and never needed to plant marigolds in it. By the time I took the frame off, the plants were big enough, and close enough together that the cats wouldn’t go digging. For whatever reason, I’m thinking now that it was lack of marigolds, my cabbage got absolutely destroyed by caterpillars. I’m going to make sure to plant marigolds near them again next year, to see if it helps or not. Thanks for the info Stephen!
I grow marigolds as well as calendula and nasturtiums in my veggie beds. I started doing it for the companion planting reasons but I largely do it now because they’re easy to propagate & control, have minimal competition with crop plants and look pretty. I now believe in bringing in all bugs and letting them fight it out rather than trying to deter or kill specific pests. I get great pleasure from seeing predator bugs in my garden and hope that I’ll one day enjoy the herbivores as much. I think encouraging diversity of plants, insects and micro organisms is key. good luck with the trial – it will be interesting to see the results and your conclusions.
Thanks Stephan, I love the idea of companion planting and have planted Marigold in almost every garden I’ve had. I do see a difference when having them in my garden, especially with the tomatoes. I am surprised at many of the other companion plants mentioned in “Carrots love Tomatoes” that I never knew about. I’m anxious to hear about more of your findings.
I had started using Humic/Fulvic acid not only in my garden, but to start seedlings. My seeds germinated very quickly and had a positive effect on the plants. Is this something you and Patrick will be testing in the future? I’m looking for a correlation between the benefit of compost tea and the use of humates as compost tea must contain humates at a molecular level.
Does companion planting work to deter pests? Today we are going to discuss marigolds? What companion plants have you tried in your garden? #companionplanting #companion #marigolds #marigold #pestcontrol #pests #insect #insectcontrol #science #organicgardening #organic #organicfood youtu.be/nWWmSma8IvE
I think you (and some in the comments) are confused as to which marigolds are for doing which job. Calendula is known as pot marigold. This is the flower that is used for calming skin irritations and is NOT a ‘true marigold’ as it is in the daisy family. This is a VERY useful flower both medicinally and topically, but I’ve never heard of it being used specifically as a companion plant to kill pests (although it does attract beneficials). French Marigold is the superstar of the marigold family – Tagetes patula. *This* is the plant that kills nematodes in the soil and keeps other pesky pests away. If its roots are left in the soil they can deter nematodes for 2-3 years as they decompose.
I’m planning to add pepper on an elevated bed with coriander already growing on it for almost a year(in fact I’ve already gathered some seeds), are these two a good combination since I read that coriander is a good insect deterrent? Also is adding wood chips and twigs on top of the bed harmful by draining the soil of nitrogen for decomposition or is this only dangerous if the wood is mixed in with the soil? Thanks.
I find gardening interesting and fun, but sometimes overwhelming as I’m quite the perfectionist. It makes me want to do it the right way, but as you know that’s impossible as there are way to many variables. 🙂 Last year I had great and unexpected success for most of my edible crops, but this year I had almost total crop failure in everything but my rhubarb and green beans. I love perusal your and Patrick’s experiments in things that have only been sparsely researched before. 🙂
Excellent series on scientifically testing assumptions- There’s a ridiculous amount of expert advice that’s that’s not based on anything but biased opinions. I won’t bother with marigolds, but I think that next year I’m going to test out planting a row of dill weed next to my squash since I’ve heard rumors that squash bugs are repelled by the scent of the dill. It sounds too good to be true, but growing dill is so easy that I’m giving it a shot. Probably plant some ‘control’ squash in another spot to compare to the others.
Love your objective approach to growing veggies in backyard gardens! And I appreciate your efforts in posting such interesting and informative topics. I’ve been veggy gardening using raised beds for about 9 years. Seven of those years was in Ottawa, ON, Canada (en.wikipedia.org/wiki/Ottawa), where I grew (among many other things) brussel sprouts with nasturtiums nearby as well as dwarf Marigolds. The nasturtiums were always infested by aphids. Not a bad thing of course. Two seasons ago, I moved to the Okanagan valley (en.wikipedia.org/wiki/Okanagan) where I set up the same type of raised beds. My nasturtiums failed in both seasons while my sprouts (and broccoli) were infested with aphids (they also attacked my one-season experiment with artichokes). BTW, my regular treatments of insecticidal soap also failed. In Ottawa I always planted a small section of Marigolds and Nasturtiums in each of my 4′ x 4′ raised beds. I’m not sure if the marigolds do anything but they look good. I’m hoping that if I can get the damn Nasturtiums to grow, I’ll not have an aphid problem with my kale-type veggies.
Your research talks about “Pot Marigold” but I was under the impression the Calendula is pot marigold not the sweet orange and gold ones in your photos. I had accidentally excellent pumpkins last year that were volunteers that came up among the pole beans and were not bothered by squash bugs as squash in other parts of the garden.
Good information. Marigolds are also supposed to deter mosquito’s. Nasturtium flowers are edible, they taste peppery and are great in salads, they also deter aphids and some beetles but I have not seen recent studies to prove that. Onions and Garlic are also good companion crops especially in the case of growing carrots, where there stronger smell masks the smell of carrots from the carrot fly. Thanks for sharing.
Can you mention some more companion plants? It would be interesting to have all your subscribers try a series of companion plants and compare results. I planted a marigold from Burpee Seeds called Nemagone which was supposed to be specifically bred to kill nematodes. But I read you weren’t supposed to plant marigolds in the same place every year because what ever causes marigolds to work against nematodes becomes ineffective if you don’t rotate plants. Have you come across that information?
Being a professional gardener in multiple states now, I’d say yes and no. If you want to deter deer and other vermin this way you have to do waves of plants just like you’d do for visual affect. Often times its the flower or leaves that are either older or younger that deter the pests. It’s not just, put a plant in and walk away. You also might be surprised that deer and other pests like your pest controlling plants at different stages of their life cycle. Then theres always that neighbor or relative who tells you…oh my. The deer and rabbits here dont eat those plants! Well, the pests in their world might not be starving or, might hit have developed a taste for something that isnt neccesarily good for them. Its It’s all trial and error like most farming/gardening/landscaping. I would not recommend giving up though. Keep working at it and researching. I have often found it’s the amount of a pest controlling plant a customer has planted. 1 or 2 plants are not going to deter a herd of deer…..or even 1. Lol . Keep trying though. It works.
I’m planning to add pepper on an elevated bed with coriander already growing on it for almost a year(in fact I’ve already gathered some seeds), are these two a good combination since I read that coriander is a good insect deterrent? Also is adding wood chips and twigs(not burned) on top of the bed harmful by draining the soil of nitrogen for decomposition or is this only dangerous if the wood is mixed in with the soil? Thanks.
Nice livechat! Thanks..and enjoy the New Year in the garden! I have access to horsemenure with peat litter in it. I put that in my garden to mix it with my hopeless claydirt. It seemed to have worked out well…but maybe it must be composted more before using? Do you have any thoughts about that?? Answer much appreciated…because my plan was to do it all over again…Gina in Sweden🇸🇪
