What Attracts Weevils In House?

Weevils are insects that live in almost all environments and are attracted to moisture, finding ways into homes when the weather is hot and dry. They often enter homes through cracks and openings along doors, windows, or the foundation. They are most common in kitchens, where they feed primarily on grains but earned the name “flour bugs” because they are often found feeding in flour.

To get rid of pantry weevils, you can grow plants that deter weevils, such as lavender and scented geraniums, and learn how to attract and kill them. Weevils are attracted to warm, moist environments and emerge in late spring and seek shelter in the hot, dry months of June and July. To tackle any weevil infestation in your pantry, you can trap them in shallow pans of water placed around the foundations or walls of the house. However, these pans do not capture enough weevils to reduce the number of weevils entering homes.

To keep adult weevils out of your food sources and prevent a weevil infestation, you can discard infested food and keep grain weevils out of your food items. Weevils can be found indoors from the end of June through August and are attracted to moisture, such as sinks, bathtubs, and water basins. Some species, like the Asiatic oak weevil, are attracted to lights and gather around the doors and windows of houses.

Weevils prefer the dark, so during the day, they will seek out dark corners of the pantry or other warm, moist areas inside the home. To clean any weevils, wipe the shelves with hot soapy water or a disinfecting spray, then wipe again with white vinegar, which is known to kill weevils.

In summary, weevils are a pest that can invade your pantry and cause damage to your food items. By using natural deterrents like bay leaves, you can help prevent future infestations and protect your home from the harmful effects of these pests.

How Do I Permanently Get Rid Of Weevils?

To effectively eliminate weevils from your pantry, start by discarding any infested food items, particularly unsealed dry goods such as oats, rice, flour, and packaged products. Next, thoroughly clean your kitchen cabinets by removing all contents and creating an organized pile on the floor. Wipe the shelves, walls, and surfaces with hot soapy water or a disinfecting spray, followed by a cleaning with white vinegar, known for its ability to kill weevils and their eggs. In more severe infestations, consider using kitchen-friendly pesticides to trap and kill weevils.

Buying grains in bulk can help you check for infestations before purchasing, decreasing the likelihood of bringing home weevils. Be mindful of their life cycle: adult weevils, which have hard exoskeletons and wings, mate and lay eggs, prompting further infestations if not addressed.

After cleaning, ensure you're proactive by maintaining sealed containers for dry goods to prevent new infestations. The cleaning process not only helps to eliminate current weevils but also prevents future outbreaks by minimizing the chances of eggs hatching. Regularly inspect pantry items, and if necessary, heat affected products to at least 140 degrees Fahrenheit for 15 minutes to kill any hidden weevils, eggs, larvae, and pupae. In summary, thorough cleaning and proper food storage are key strategies for preventing and managing weevil infestations in your pantry.

What Do Weevils Hate?

Herbs effective as weevil deterrents include bay leaves, cloves, rosemary, black peppercorns, and garlic cloves. To protect grains, flour, and cereals, place a few bay leaves inside their containers while using the other herbs on pantry shelves to avoid flavoring the food. Weevils, also known as flour bugs, thrive on various crops but do not pose threats to humans or pets, acting mainly as temporary nuisances that spoil stored food. The most common types found in kitchens are rice and granary weevils. There are over 1, 000 species of weevils in total, and they usually enter homes through groceries rather than from outside.

While they do not harm people or pets, nor damage property or infest food products, they are considered a temporary nuisance. Weevils primarily feed on plants, and some species are significant pests as they damage crops and ornamental plants, such as roses. They are predominantly herbivores, consuming various plant parts, including leaves, stems, buds, flowers, seeds, and roots.

In the UK, wood-boring weevils are responsible for less than 4% of beetle attacks. Various weevil species have specific dietary preferences; some target plants while others may infest stored products like flour and grains. For instance, certain weevils prefer fruits and nuts, while others may avoid grains entirely. The weevil’s larvae typically develop within plant structures, such as roots and stems.

Infestations can occur in homes when plant-feeding weevils seek shelter or when seed-feeding weevils are accidentally introduced through food items. The grain weevil (Sitophilus granarius) is known for damaging stored grains, including pasta, flour, cereal, and rice, by boring holes and laying eggs, which may ruin the food. The wood-boring weevil specializes in consuming wood, yet not all weevil species do.

There are over 97, 000 different weevil species, with some associated with damp environments. Although they can be a nuisance in homes, experts suggest there is no need to panic about food infested with weevils or other beetles.

What Do Weevils Turn Into?

Weevils are small beetles belonging to the family Curculionidae, known for their elongated snouts, with over 40, 000 species worldwide, approximately 97, 000 identified. The lifecycle of a weevil includes four stages: egg, larva, pupa, and adult. Upon hatching, the eggs become larvae that resemble small, white or yellowish worms, which feed voraciously on grain and other plant-based food sources. The larva develops within the grain kernel before transforming into a pupa, where it undergoes significant metamorphosis. Adult weevils, emerging with hard outer shells, are typically less than 6 mm in length.

Weevil species typically lay their eggs either in the soil near host plants or by boring holes into plant stems or seeds. Once laid, the eggs hatch into larvae, which feed on surrounding materials. Common weevil types found in Canada include the sweet potato weevil, rose weevil, and rice weevil. Their presence in homes is often due to their search for food and shelter, as they can enter through various means including packaged foods.

The larval stage may last up to two months, followed by a pupal stage of about three weeks. Infestations in stored grains can be problematic, but experts suggest that it's manageable without panic, emphasizing the importance of safeguarding food supplies against these pests.

What Do You Spray To Get Rid Of Weevils?

To effectively eliminate weevils, utilize products like Ortho® Insect, Mite and Disease 3-in-1 or Ortho® BugClear™ Insect Killer for Lawns and Landscapes, always adhering to label instructions.
