1. Prevention and control of fleas on sheep's body surface

Removing fleas from animals is one of the goals of prevention and control, and the other goal is to inhibit flea reproduction. Persistence is the primary index for selecting pesticides, and it is also an effective method to kill fleas or use compounds that can inhibit their reproduction before they breed. Avermectin and thiophanate-methyl tablets are commonly used to repel insects in spring and autumn.

2. Governance of fences and surrounding areas

In Liaoning, April is the best time to control fleas, when fleas just entered the breeding season. Clean up the sheep manure in the pen as soon as possible, store it in a unified way, water it, and then cover it with plastic sheets for compaction. After a year of fermentation, sheep manure can be used as farm fertilizer in the following spring.

Smoke-carrying medicine technology can be used for outdoor prevention and control, with good smoke diffusion, and can reach places where other methods are difficult to prevent and control. Smoke emitted by a cleaning machine or a hot fogger can penetrate into the gaps between articles and cracks in walls and floors, thus killing pests.

3. Indoor governance

The indoor sealing control effect is obvious. Flea adults can be killed by fly-killing drugs, and the window should be opened for ventilation after spraying for 3 hours to prevent poisoning, and the toxicity of drugs to the environment and people, especially to children, should be fully considered.

In aquaculture areas, it is best for the local government to come forward and organize all households to spray drugs at a unified time, so that fleas have nowhere to hide, and ensure that the source of fleas is cut off and fleas are completely eliminated.

4. Governance of feed warehouse

You can use a grain worm net to spread it in the feed bin. This medicine has no toxic side effects and is harmless to sheep.
