The bite of the gadfly has certain toxic toxin, but it is not life-threatening. Being bitten by a gadfly is painful, accompanied by bleeding, and at the same time it will produce erythema papules and wheal. Because the bitten wound is stimulated by the gadfly's saliva, it often forms painful swelling, which causes great trouble to domestic animals.
After being bitten by a gadfly, you can apply refreshing antipruritic agent, corticosteroid preparation and other drugs. If the situation is serious, even if there is erosion and exudation, you can go to the hospital to do local cold compress and wet compress and take some medicine.
Driving method of gadfly
1, coumaphos powder
25% coumaphos powder is diluted into aqueous solution (concentration is 0.5%-0.7%) and sprayed on cattle. This method has obvious effect and will not produce great side effects.
2, wind oil essence
Prepare a bowl of clear water and add a few drops of essential oil. Stir well, then pour it into a small sprayer and spray it on the cows (each cow sprays 1 bowl). If there are too many gadflies or the aqueous solution is too weak, it can be sprayed again at noon 1 time.
Step 3 tap
In places where livestock gather, once the gadfly is found feeding on livestock, it can be patted off gently with a fly swatter (be careful not to use too much force to avoid the insect body being smashed).
