Q: Can any products prevent the transmission of heartworm from infected mosquitoes to non-infected dogs?


According to the new CAPC Mosquito Control Guidelines, there are several products available for use on dogs to repel and kill mosquitoes for an entire month.

These spot-on products are not labeled for use in cats, nor should they be used in cats. Long-lasting permethrin-impregnated clothing and bedding is also available for dogs (not cats) to repel mosquitoes. Mosquito control products approved for use on dogs should not be used on humans.”

A complete list of available ectoparasiticidal products is available at capcvet.org.
