After entering the winter, most pests entered dormancy. This is the best time for the annihilation of storage grain and fruit trees and field pests. The main methods of extermination in winter are: 1. Killing. For winter pests hiding in grain, cotton warehouses and seed warehouses, the doors and windows of the warehouse can be opened in cold weather, so that the temperature of the warehouse falls below 5°C. In this way, even if it is frozen several times, the pests can be frozen to death or their reproduction can be inhibited. 2. Spawn eggs. If you find pests on the trunk or branches of eggs, you can use Burlap or loofah to wrap up the branches in the trunk, and forcefully move back and forth to kill the eggs. 3, scraping skin. There are many kinds of pests hidden in the bark, tree joints wintering. Knife can be used to scrape the tree's rough skin, warp skin and scratch the insects. Spraying 3-5 times of lime sulfur on the fruit trees after scraping will have better control effect on insects such as scale insects and red spiders.
