Weevil is a small beetle that seriously creates tremendous destruction to growing plants and stored grains. There are over 40,000 identified species of weevils. The mouthparts of a typical weevil are shaped into a long snout. It comes with an antenna on both sides. In several species, the snout is longer when compared to the body; which rarely develops to one-half inch (13 mm) long.


The snout is used not alone for eating, but as well, for creating cavities where the eggs are laid in sprouts, fruits, seeds, stalks, and roots of plants. In the event the grubs (larvae) emerge, they feed inside the plant segments. Infested fruits drop from the trees, or turn out to be stunted, damaged, or wormy, and tend to be not fit to eat. Buds and seeds are damaged by weevils and their larvae, and vegetation is destabilized by their attacks.

Weevils are nasty beetles – with regards to gardening and farming. The weevil inflicts damage by eating plants. It is likely that at least one kind of weevil enjoys eating nearly every grain, fruit, or vegetable. The boll weevil stands out as the major insect pest of cotton. The alfalfa weevil is really a harmful pest of alfalfa. The plum curculio attacks apples, cherries, peaches, as well as plums. The acorn weevil eats acorns. The rice weevil along with the grain weevil feast upon stored tiny grains and lay their eggs inside the grains. Once the eggs hatch, the larvae eat throughout the plants from the inside out.

Weevils Possess Big Snouts.

A weevils snout is curved downwards so they can bore into plants. At the tip of the long snout are the weevils mouth parts that munch fruits, seeds, and other plant parts. Different species of weevils have different types of snout forms. Every single form is adapted to eating particular plants or parts of plants. For instance, the female nut weevils snout is usually longer than its body. It requires a long snout to bore through the hard shell of a nut in order to lay its eggs inside.

The two most popular types of pantry weevils are the granary weevil and the rice weevil. Generally known as snout weevils. These tiny kitchen pests are actually beetles; very tiny beetles that seldom grow any bigger than ¼ inch. Female weevils use their small snouts to drill holes in the casings of grains, just like barley, beans, corn, oats, rice, rye and a variety of seeds. As soon as the hole is drilled, she deposits an egg and seals the hole back up using a gelatinous glue-like material she produces herself. The egg hatches after a couple of days, and the larvae make use of its environment for nourishment for about the following month.

Because of this, it can be hard to identify an infestation. It is not only sluggish to begin but the larvae are in hiding. The moment grain weevils or rice weevils present themselves, you then have a problem.

Just one female can lay as many as 400 eggs, meaning as many as 400 more hungry bugs hunting for food. If you have encountered something such as this, it is important to learn how to control and eliminate weevils.

Weevil Control

Remove all contaminated foods. This might be the best step in doing away with weevils. Examine throughout the kitchen, including every single cabinet, for any food items that may be contaminated. If you find something you are not certain of, discard it. There is absolutely no reason for jeopardizing reinfestation. It could actually empty your pockets over time. Upon collecting them up, take outside to the garbage container right away, and transfer the can as far off from your house as you possibly can.

Perform the most thorough cleaning of your kitchen and cabinets that you have ever achieved. Begin with taking completely anything off the shelves and vacuum-cleaning them. Ensure that you get all the cracks in which flour or other food bits could possibly be hiding. In case you have contact paper lining the shelves, take it off. Work with a rag and some hot sudsy water to complete all of those other cleanings.

Weevil Elimination

Destroy weevils using cold. To protect yourself from future difficulties with weevils, you need to freeze your food. Freeze cookies, cornmeal, flour, grits, oats, anything of this kind. If you have the room in your freezer, you ought to just maintain the stuff in their full time. Should you have a small freezer and can’t afford the space, set the freezer as cold as it gets and then leaves the food in there not less than four days. That will destroy any eggs, larvae, or weevils.

Destroy weevils using heat. If you do not feel like freezing everything, just a little heat exposure will achieve the same thing. Spread your food or seeds very finely on a baking sheet, preheat the oven to 120°F, and then leave it in there for an hour. Should you be impatient, you can try 130°F for half an hour. If you’d like to use the microwave, spread the stuff on a plate or glass dish, and run it for 5 minutes.

Remember that if you are heating seeds for gardening, the heat could possibly damage the seed’s possibilities for germination. Furthermore, never heat fine-grained stuff, such as flour, in the event of combustion.

More weevil elimination. Begin with cleaning the cabinets and kitchen on a regular basis. If you happen to spill something, clean it up right away and thoroughly. In the kitchen and cabinets, you really should consider sealing any shelving cracks with caulk to keep food from becoming trapped in that area later on. Purchase goods in smaller amounts that can be used instantly. Rotate your supply and do not mix fresh food with old. Last but not least, keep all of your perishables in tight-lidded plastic, glass, steel, tin storage containers.

Natural Ways to Handle Weevil Infestation

Bay leaves. Bay leaves are in fact a natural weevil deterrent. Following freezing or heating your grains, put a bay leaf or two inside the storage container atop the food item you wish to protect. You may as well randomly spread some leaves throughout the cabinet or kitchen.

Cloves. Cloves are also a natural deterrent for weevils. Treat your grains using cloves exactly the same way you would using bay leaves. Soon after treating your food with hot or cold, place a clove on top of it prior to storing. Spread a couple throughout the cabinets and kitchen as well.

Chemical Control

With as prevalent a kitchen pest as weevils are, you would think that there could be quite a lot of pesticides that particularly target them. Sad to say, this is not even close to the situation. The reason being is simple: weevils stay and reproduce in your food. Because you wish to eat that food, contaminating it with insecticides probably just isn’t the most effective idea. That is why, you’ll want to just continue with pyrethrins. There are a number of various pyrethrin aerosols and sprays available to use indoors, as well as in food handling locations. You must still avoid spraying the food directly. When your kitchen and cabinets are totally empty, spray them down. It is best you then leave the cabinets empty and open for not less than a few hours prior to filling them back up.
