How Do You Kill Beetles In Soil?

Effective insecticides for garden beetles typically contain synthetic pyrethroids like bifenthrin or cyhalothrin, and carbaryl may be used as well. To control beetles, you can hand-pick them, employ home remedy sprays, and set up beetle traps. Employing row covers, planting beetle-repelling plants, and practicing good gardening is essential to prevent beetle infestations. When planting, spray insecticides directly on the surrounding soil to minimize pests like spider mites, gnats, and aphids; however, hydrogen peroxide won't eliminate eggs. Moist potting soil is crucial for thermal pest control, as dry soil conducts heat poorly. Proper temperature and time are necessary to effectively eliminate pests.

To manage red lily beetles which overwinter in soil, loosen the top few inches of soil around lily stalks in autumn. Apply neem oil or insecticidal soap to affected plants. For lawns, treat grubs with imidacloprid or halofenozide, and maintain healthy plants while avoiding overwatering to deter beetles. To prevent indoor beetle infestations, regularly vacuum, declutter, and store food in sealed containers. Natural repellents, such as diatomaceous earth, can also help.

For beetle population control in gardens, identifying the specific beetle species is vital. Create species-specific pheromone traps to capture adult beetles and disrupt their mating cycles. Sevin Insect Killer Dust can kill flea beetles instantly upon contact.

Does Dawn Dish Soap Kill Beetles
(Image Source: Pixabay.com)

Does Dawn Dish Soap Kill Beetles?

To control Japanese beetles in your garden, mix a couple of tablespoons of standard dish soap, such as Dawn or Palmolive, with water in a small container (approximately two cups). Empty beer or soda cans can be effective as they prevent beetles from escaping. The soapy solution drowns the beetles, as they drop to the bottom before releasing pheromones. To create the solution, mix 1 teaspoon of dish soap per quart of water. Though dish soap acts as a cleaning agent and not an insecticide, it can effectively kill pests like Japanese beetles, aphids, and ants through suffocation.

Spraying any insect with the soap-water mixture can kill them. The soap's active ingredient, sodium lauryl sulfate, acts as a surfactant, breaking down the beetles' waxy coating and leading to cell breakdown. A common approach is to create a homemade spray by mixing 4 tablespoons of dish soap with a quart of water. This solution can be sprayed directly on beetles found in gardens and lawns.

For pest control, it is recommended to handpick Japanese beetles and drop them into soapy water, where they can’t escape. The soap works by preventing them from flying away, causing them to drown. In general, dish soap has minimal toxic effects on beneficial insects like ladybugs and lacewings, making it a safer option for use in gardens.

It's important to note that while soap can help in repelling and killing beetles and other pests, it does not act as a standalone solution; combining it with other methods may improve efficacy. Insects breathe through tiny openings called spiracles, and the soapy water clogs these, leading to suffocation. Overall, using a soapy water solution is an effective and natural way to manage Japanese beetle populations.

How Do I Kill Beetles Eating My Plants?

To control beetles in the garden, some gardeners utilize a mixture of soap and water, with optional additions like vegetable oil, cedar oil, garlic, or cayenne to deter beetles. Effective methods for beetle removal include hand-picking, home remedy sprays, and traps, alongside preventative measures such as row covers and beetle-repelling plants. It's crucial to identify and eliminate leaf-eating beetles promptly to protect your plants.

The University of Minnesota highlights the importance of recognizing potential infestations, particularly from cucumber beetles that harm plants by feeding directly or through infection, with larvae targeting roots and adults damaging stems, stalks, and blooms.

To spray beetles, focus on the undersides of leaves. Another method involves shaking leaves over soapy water-filled jars to catch falling beetles. Neem oil, a traditional remedy, can also aid in combating beetle populations. To manage Japanese beetles, which threaten a wide range of plants, it's helpful to cultivate plants they tend to avoid, including arborvitae and lilac. During early mornings or evenings, when beetles are less active, manually removing them into soapy water buckets is time-consuming yet effective.

Various home remedies like peppermint, diatomaceous earth, and beneficial insects can further assist in controlling beetle populations naturally. Lastly, conventional methods like batting and insect exclusion can reduce infestations.

What Attracts Ground Beetles
(Image Source: Pixabay.com)

What Attracts Ground Beetles?

Living mulches, such as red and white clover, enhance microclimates and attract ground beetles, which are vital for gardens (Blubaugh et al., 2016). These beneficial insects help control pests and contribute to soil health by decomposing organic materials. Ground beetles inhabit soil beneath mulches, compost piles, and sheltered areas, creating vertical tunnels. They play a significant role in weed management by consuming seeds from plants like common ragweed and crabgrass. To encourage ground beetles year-round, gardeners can establish a beetle bank, which aids in their residency.

Active primarily at night, ground beetles seek shelter in logs, stones, and grassy areas during the day. They are adept hunters, feeding on slugs and smaller beetles, emerging from their burrows at night to prey on soft-bodied creatures. With around 34, 000 species globally, ground beetles are prominent predators in various ecosystems, with approximately 350 species found in Britain.

To promote these insects in gardens, it is crucial to create habitats like wood piles and compost heaps. Living mulches can significantly increase their populations. Additional methods to attract ground beetles include maintaining leaf litter, utilizing log and rock piles, and employing outdoor lighting to draw them in. Lastly, an open compost heap provides access for breeding ground beetles, making it an effective strategy for increasing beetle presence in the garden ecosystem.

  • Beneficial nematodes are the greatest discovery I have ever made. Garden grubs (or curl grubs as I know them) almost made me quit gardening altogether. The thought of them being in there and me not really knowing was too terrifying. But now I legit relish when I find grub carcasses from nematodes. Also neem oil can really help too. I tend to do neem oil during the colder months and then bring in my nematodes for Spring/Summer to keep on top of them.

  • I’ve been researching nematodes. From what I’ve seen, you want wet soil during application and after. The nematodes only are viable for two weeks once you get them so timing is pretty crucial, especially if you have a larger area to spray. I’ve also seen recommendations to apply them at dusk. One user said the nematodes will feed and spread out until they no longer have a food source or the ground gets too dried out. I’m planning to apply nematodes this fall here in middle Georgia and also in the early spring to interrupt the life cycles and catch more things hopefully. We have a huge gnat and ant (Argentine ants, not fire ants) problem here where I live in addition to the usual garden suspects so I’m hoping this helps manage that.

  • So many people in the comments say they love the nematodes and have been using for years, and I’ve been perusal gardening YouTube for several years and never heard of them! I only had ever heard about the harmful type of nematode. They seem awesome. Might need to try in our So Cal yards this fall; we got termites and ants around for sure. Thanks for the excellent demo

  • Good point about aiming the nematodes at the base of plants! I just released some today in April! It’s recommended to do a couple of applications 1-2 weeks apart and make sure to remove any filter or screen in the hose end spray if you’re using one. Also apply early am, dusk, or on an overcast day. UV light kills them.

  • I applied in the cool fall weather in November. Most of the beetles in my garden were gone and I was at the height of grubs in my soil. Nematodes need a host in order to survive to move on to the next grub. More grubs in the soil, the longer most of the nematodes last in the soil reducing the population. Milky spores also benefitted my garden over the last few years.

  • This is the best demonstration of nematode application I’ve seen. I usually order them from Arbico Organics twice a year when I change over the crops. But I have gone through several sprayers trying to get them to work. They always clog my sprayers. So I just resorted to mixing in my two gallon watering can to do each bed I see now how to dilute the solutions. Thanks for the vid

  • I’ve heard of beneficial nematodes but forgot about them, thank you for the reminder! I didn’t know they also kill fingus gnat larva. I’ve been occasionally using dissolved mosquito dunks in my pots to combat indoor fungus gnats on vegetable plants I take inside before winter. The dunks don’t seem to help much and each year the gnats have overrun things and contributed to me giving up on growing veggies indoors. I use the sticky yellow paper stakes to catch adults but that doesn’t nip them at the source. Hopefully some nematodes will be a better solution!

  • Thank you for posting this! I just rewatched as I’m currently prepping my garden for spring here on the border of 9b/10a. So much good information. Have you or Kevin ever released other beneficial insects? I’m considering purchasing lacewing eggs on cards when it warms up and would love to watch a article similar to this one 😀

  • I am in zone 10a and am so glad I found you and Kevin ;), cause i am a hack gardener. I have 3 self-watering raised beds (from Costco). They are new this year and full of good soil and GRUBS. I also have watering troughs with vegetables that also have GRUBS. My husband wants to empty out all of them and get rid of the GRUBS that way and then use nematodes. What is the best wat to eliminate the GRUBS? Also, when you did this article you sprayed nematodes into a container with GRUB in it, how long before the GRUBS died?

  • I put beneficial nematodes around my yard once a year at least. Mostly to expand my control on Japanese beetle grubs. AND I use this company. Since Japanese beetles can fly in and lay eggs, I do add it every year. I have seen number reduction of Japanese beetle specifically from year to year. And I’ve seen when I don’t do it after a few summers – the beetle numbers increase.

  • I recommend if using them to use all of them once opened. I purchased them and used half and was going to use the other half a month later and had them in my fridge until I was ready to use the rest well because I put the opened container in my fridge they literally infested my fridge and freezer and got in all the small cracks. I had to get a new fridge bc they kept coming back and even got into the ice.

  • I caught 12 of the Figeater grubs, put them in a bucket with soil, put 5 million HB NemaSeek in the basket with water, only 3 were killed, after 2 weeks, so I’m wondering what, why, as I’ve tried it on 2 seasonal applications of the 3 varieties, 2 years in a row, they are out of control. My only control is hanging a watermelon rind over a bucket hung in a tree, with water in bucket, at the best day from 5 traps I collected almost a 5 gallon bucket of bettles, I’m asking for your tips.

  • Hi . Help please. I have the same sprayer. I usually use it to spray been oil. The been bottle says to dilute 1 gallon into 6 tsp, but this dilution is for the pump sprayer, I believe. Since I use the sprayer with the hose, I just pour the concentrated sprayer but I have a hard time where to set dial for the correct mix amount.

  • I tried this nematode method and bought from arbico and I still have huge larve grubs eating the roots of my plants.i kept my beds wet for a week, applied them at night and the days after application were cloudy. Any other ideas? Do I have to keep applying until they’re gone? It seems like it would get expensive quickly 😅

  • I just got my Nematodes!!! Thank you so much for this tutorial cause the grubs are hitting me hard! I built that screen sifter thing for the containers, some had 2 grubs others had 15! Ahhhhhh! I soaked my beds last night and I’m going to spray the Nems tonight. Question – I have freshly planted potatoes, should I pull them out then spray or is it okay to leave them? It’s about 15 potatoes in a raised bed so wouldn’t be too much additional work. Also, I have a huge pile of compost, should I spray the pile? I could see beetles laying eggs in there maybe. Thanks again for all the info!!!! Ayyyyyy!

  • Did you buy the nematodes from a garden shop or plant nursery? Or somewhere else? I’m having trouble finding them in Australia – we have the same grubs and they’re killing my roses 🤬🤬🤬 and all my herbs – they seem to be partial to the roots of onion family plants. Also, do you need to treat (pots and planters, not garden beds) regularly or just a one-off treatment? (I don’t know why, but I can’t comment on the long article about this).

  • I tried an application 3 weeks ago, no luck 🙁 Purchased from amazon, perhaps not a good batch. I researched further from UC Extension Service (Im in 10a) that what I have is Fig Eater Beetles not June Bugs and that they are supposed to not eat roots. So confusing. Pill bugs and Ear wigs are also an issues for me, perhaps I’ll try again. Thanks for the article Jacque !

  • Chirp is going to be so bummed you are getting rid of all of the grubs! I actually enjoyed plucking them all out of my raised bed, after the grossing out and tossing first 75 into my neighbors yard, I would just tap them, they’d curl up into a ball, I’d grab them, and toss them into a tub for the chickens.
