- Soda from wasps is used during the ripening period of the berries, when chemical protection is prohibited. Soda solution increases the sugar content of the berries, prevents the formation of rot, promotes healing of the berries after punctures with insect proboscis, helps to discard wasps. At 10 liters of cold water will need 5 tbsp. tablespoons of baking soda, 20 ml of liquid soap. To process the grapes from wasps should be in the evening or early in the morning.

It is allowed to apply chemistry directly to the processing of berries if there is more than 20 days left before the harvest. Before eating you need to thoroughly wash the clusters. Poison mixed with bait, placed in the vineyard not on the berries, can be used during any period of the growing season of the plant.
Boric acid
One of the proven means of folk "medicine" is the use of boric acid. The product is sold in a pharmacy in the form of a white crystalline powder. It has intestinal effects. The action begins after getting into the stomach. Causes muscle paralysis, death.The proportions of boric acid from wasps should be such as not to interrupt the taste of the bait.

The solution is prepared immediately before use. The maximum effect lasts 4 hours, the residual effect is from 14 to 30 days. Initially, the poison acts by contact. Insects die within 5-15 minutes from muscle paralysis. Then the poison is absorbed by the tissues, killing pests in the process of feeding.
If wasps eat grapes, the culture should be treated with modern, effective, odorless insecticidal drugs - Lambda Zone, Geth, Delta Zone. Sold in the form of a concentrate. When working with drugs, rubber gloves, a protective suit, a respirator should be used.

- The solution of baking soda with soap and water can protect against the attack of a berry. The tool enters the body with a bite, repels bitter aftertaste. In the stomach, soda causes increased gas formation, which is dangerous for insects to die. Spraying is carried out at any stage of the growing season. You can spray the solution using a household spray bottle, spray bottle.
