How to Get Rid of Weevils and Keep Them Out of Your Pantry

Architect Richard Neutra's private residence in Silver Lake seemed radical at the time, a glass house with rooftop and balcony gardens. It housed his office and two families on a small 60 x 70-foot lot. Here's what you need to know about the different types of weevils and how you can protect your food. After suffering these injuries, the insects will lose the protection of their carapace and slowly die from dehydration. The individual particles are extremely hard and rough, and they lacerate the exoskeletons of insects, including weevils. One of my favorite insect killers, diatomaceous earth has long been used as an effective, persistent insecticide.
Avoid purchasing dry goods in bulk
Keeping your home bug-free and spotless doesn’t always succeed despite your best efforts. Rice weevils, bean weevils and other stored food weevils feed inside food packages. Homeowners might spot adult weevils wandering on the shelves or floor of the pantry. Of the some 40,000 weevil species, the ones that threaten your pantry are rice weevils, maize weevils, and granary weevils.
How to get rid of small black bugs
The small black bugs can range in size from tiny fleas, ticks, bed bugs, and gnats to larger bugs like carpet beetles, black ants, and pantry weevils. Discover how to prevent weevils and keep this insect from wreaking havoc on your pantry. Keep food in containers with airtight seals with secure, insect-proof lids, usually made of glass or metal. Before buying dry items, look for open or ripped packaging and freeze grains or dry items for four days to kill bugs. Your whole pantry is in danger of infection if you find rice bugs in your grain products or another dry food source like pet food.

Learning how to get rid of weevils may involve using several simultaneous but simple strategies. Orkin can help identify the source of the weevil infestation. An Orkin Specialist is trained to help get rid of weevils and to help keep weevils from invading your home.
Remove the dry food from the freezer after the recommended time and separate them by type on the counter. Pour the flour, wheat, rice, and pasta into food containers, add a bay leaf, and secure them with a lid. The lifespan of a weevil—from egg to adult—can last between 5 and 8 months, depending on the type of weevil and its living environment. In that time, a female weevil can produce as many as 400 eggs. She perforates seeds or kernels, lays her eggs in the food, and then seals them with a secretion.
It’s vital to prevent infestations of small black critters in your house. Typically, common household pests get into buildings through cracks and crevices around window frames and doors. Other small black pests like ticks, pantry bugs, bed bugs, and fleas may hitch a ride on your pets, clothing, or shopping. Pantry weevils are fairly small insects, so it is easy to overlook an infestation in your food storage areas. They are tiny, blackish-brown, and they are characterized by their noticeably long snouts not found in other types of insects. The three types of weevils that make up the group of common indoor kitchen pests range in size from 1/8 to 3/16 inches long.
Even unopened cardboard containers may be suspect if they don't have sealed inner liners that are intact. When it comes to weevils, it's better to be aggressive about disposing of suspected foods. Some species of weevils, such as the rice weevil, feed on stored food products. Homeowners may find these weevils in packages of beans, popcorn, cereal or nuts. These weevils will also attack fruit, including apples, pears and grapes. The females often lay eggs in food packages and go unnoticed until the larvae turn into adult weevils, and freezing is the best way to eliminate them.
Federal and state governments, together with cotton foundations and associations, poured millions of dollars into researching boll weevil eradication. The first breakthrough was the discovery of boll weevil pheromones, which were used to lure and trap the pests. Scientists also found out that boll weevil development and reproduction slowed during low temperatures. By applying insecticide multiple times at short intervals, they found they could reduce and limit the ability of boll weevils to survive through the winter. The lifespan of a weevil can vary based on environmental factors such as temperature and availability of food. Since 2003, she has covered home design, gardening, parenting, houseplants, even youth sports.
Household insects
Now that you've cleared up the infestation, the last thing you want is to find yourself facing more weevils in the coming days, weeks, or months. Fortunately, you don't have to use harsh chemicals to deter them. There are several natural ingredients that they are known to dislike, so placing them in and around your pantry can help keep a new crop of weevils from settling in. You see, weevils can get into your home through entry points the same way as most other common household pests, but that’s actually not the most common way. Weevils typically look like little black bugs and are members of the superfamily Curculionoidea with an estimated 97,000 known species. Of these, 83,000 species across 6,800 genera belong to the Curculionidae family and are known as the true weevils.
Shake in a spray bottle, spritz on all interior pantry surfaces, and let dry. Before putting food back in your cabinets, wipe them off with a moist cloth to get rid of any leftover insecticide.

(Heavy chemicals like bleach or ammonia won’t have any effect on the pests.) Again, concentrate on corners and cracks where weevils might hide. Granary weevils are the largest of these three, usually around ¼ inch long, but unlike maize and rice weevils, granary weevils can’t fly, so they’re easier to contain. Also known as Sitophilus granarius, granary weevils love to feed on whole grains, like cereal and oats. They’re usually black-brown or red-brown in color and lay around 200 eggs in their 8-week life cycle. Weevils won't be able to infest the food items in your pantry if they can't actually get at the grains themselves.

These tiny beetles like dry foods, such as cereals, grains, seeds, and nuts.. Keep in mind that rice weevils, which are common pantry invaders, enjoy lots of grains beyond rice, including barley, wheat, corn, oats, and rye. Weevils thrive in warm—even hot—conditions, and these high temperatures can speed up their life cycle and cause their numbers to multiply rapidly. By the time you spot those dark little bugs in your rice, odds are they’ve infested other nearby food items. Rice weevils often hatch from larvae in sealed bags of rice, so examine all pantry items—even the sealed packages—thoroughly.
Make sure to choose a product designed specifically for weevils. Use a sponge or rag to clean the surface and wipe it dry with paper towels. Spray the back and side of the pantry and the doorway as well. Replace the food items in their proper places after the shelves dry. The first step in getting rid of the weevil beetle is to clean house.
Remember to fully clean the containers by washing them with soap and hot water and then completely drying them to ensure that no moisture remains in the containers. Additionally, if you discover small bugs in your stored food or small moths fluttering around the kitchen, you will most likely need to stop the infestation and eliminate it. There are a few simple ways to get rid of weevils such as using a vacuum cleaner or a broom, or wipe the pantry shelves and cabinets with soapy water. Wash all shelves and cabinet interiors with a sponge dipped in hot soapy water, white vinegar, or a nontoxic household cleaner, and let dry thoroughly.
In her free time she enjoys cooking, traveling, and working out. These beetles are round to oval and have a long, narrow snout that seems reminiscent of an anteater’s snout or elephant’s trunk. Even more bizarre, their antennae are located partway down this snout (known as a rostrum) instead of on the head itself.
