The dogs are suddenly infested with fleas and they(the fleas) seem uncontrollable. I would like to spray Demon WP to control the fleas but I would also like to use the best IGR to be mixed with it. It is a BIG yard.
The best IGR to mix with Demon Wp for flea control would be Nyguard. Nyguard will actually stand up to the suns rays and will remain effective for up to seven months.
