The weevil is a small insect belonging to the family of beetles. It does not exceed 4 mm and their color varies depending on the type of weevil. It can be recognized by its flat back and is an invader of closets, silos and pantries.
There are several species of weevils: there are about 200,000 in the world and they can be troublesome because they feed on grains and cereals such as wheat or rice. They can also attack gardens and plants.
There are weevils that can also lodge in wooden beams, so it is important to keep them under control.
At first glance, weevils can be mistaken for moths because they are almost the same color and size. Their larvae look like tiny worms, but because they are whitish, they can go unnoticed if you don’t inspect them carefully.
The general facts about this insect will help you detect it: a female weevil can lay about 400 eggs between its four and five months of life. And they thrive in environments with temperatures between 25° and 35°C, with a humidity percentage of about 70%.
In domestic spaces, you will notice the presence of weevils when you find larvae in cereals and dry grains or when food packaging is pierced, you can even find remains of feces.
In the garden or in crops, they may emerge mainly in the spring, attacking shoots and flowers. They are active at night and if you catch them, they can play dead in a very convincing way. In this sense, it is important to fight them before they deteriorate the plants.
How to protect supplies from weevils?
When it comes to protecting your household supplies from weevils, simple measures such as storing cereals, flours and pasta in airtight containers are sufficient.
Preferably, wash the jars every time you go to fill them, taking care not to damage the wire or the edges, where eggs can be hidden.
Also try to ventilate the cabinet at least once a month, replace the paper you use to protect it as there may be eggs there. If you want a deeper cleaning, vacuum the cracks and that’s it.
If you prefer, place the cabinet in a cool but moisture-free area. Weevils are afraid of temperature changes, so ventilation will be effective.
You can also take other steps, such as finding cracks or baseboards near the cabinet and sealing them. Also try to correct any signs of moisture.
When weevils reproduce, the female puts her eggs in a grain, such as rice or beans. The larva develops by eating this grain and emerges as an adult to continue the reproductive cycle.
Since weevils can live on crumbs, try to clean up debris. Keeping your food safe is crucial because once it is infested, you can simply replace it with new food.
Do you need to exterminate weevils?
A very good technique to help you detect the presence of these insects is to put the bag of grain you think is infected on ice: when it reaches 10°C, the weevils will come out.
If it’s summer, just put the food in the sun for about 10 minutes and it will come out. We have already told you that weevils are very sensitive to temperature changes.
To fight them, you can use Onguard Pro-Perm for all types of insects. Continuing its action for two months will allow you to control weevils, while also controlling other insects. Simply apply it to cracks and crevices with the spray bottle.
