- At the site of the appearance of weevil beetles, in addition to their direct appearance, one can determine according to the state of the plant.

- A well-known stock pest, the granary is about 4 mm in size and has a brown color that is easy to spot. But in the total amount of reserves, they are quite inconspicuous. Therefore, it is advised not to prepare a lot of products.
- Plants brought from the street, especially if the soil in which they grew is not credible or unknown, it is better to leave it in quarantine.
How to deal with weevils
Methods of struggle will directly depend on which weevil wound up. There are also features depending on which plant the beetle is on. But there are a few general rules.
Chemicals

The use of chemistry is justified in the case when pests have already spread in large numbers. You need to be careful with them, because these products cannot be used on plants from which the harvest will soon begin, in a house where small children live and with food. However, chemical preparations will certainly show an effective result.
Use biopreparations to control insects if it is necessary to treat the soil. From chemical potent drugs apply Karbofos and Metafos. They are sprayed on an infected plant or products.
Folk methods
These drugs and methods will be effective at an early stage of infection. They are safe, but will require constant repetition.
- Mechanical method collecting or shaking off weevils. It is used on plants and shrubs.Do you use chemicals?
- Mustard powder. Weevil beetles do not tolerate it. A solution is made for 3 liters of water 100 g of dry preparation and plants are sprayed with it.
- Wood Ash. 40 g of laundry soap and 3 kg of ash are dissolved in water and used on plants.
- The use of herbs indoors, in places where a small amount of food is stored, odorous herbs can be used: capsicum, tansy, wormwood or mint.

| Weevil on raspberries and strawberries | This pest also infects rosaceous crops, the larvae are especially voracious as well as adults. You can fight them by mechanical shaking, as well as by putting on gauze shields or chemical compounds. |
| beet weevil | This is a beetle beetle that affects only sugar beets. This species cuts the edges of the leaves, and also affects the fruits themselves. They use their natural enemies for protection, attract birds and shrews to hedgehogs. With mass distribution, insecticide treatment is undertaken. |
| nodule weevil | A beetle that infects peas and other leguminous plants, voracious larvae harm plants by infecting the roots, and beetles gnaw out leaves, which spoils seedlings and introduce infections. They use agrotechnical methods of protecting peas and liming acidic soils to prevent the beetle from developing. |
| pine weevil | Polyphagous beetles that attack not only conifers, but also deciduous ones, but the larvae prefer exclusively coniferous. These beetles, during mass distribution, infect a huge number of hectares of plantations. Even mass spraying with insecticides from the air was used to protect coniferous forests. |
| house weevil | Weevil in the apartment and house weevil can appear in food stocks. Often it is brought in when buying poor quality goods.
