How can I protect pets and livestock from West Nile virus infection?
The best way to protect them is to reduce the amount of mosquito activity in the area. The most effective means of doing this is to reduce or eliminate all standing water. If standing water, such as in a fish pond or stock tank, is permanent then it can be treated with floating Bti briquets or similar larvicides. The use of insecticides to control adults also may be warranted in certain high risk situations. If possible, animals should be kept indoors at night.
