I've known that my yard has a flea problem, and I treated / sprayed the yard with permethrin with one of those spray bottle thingies where you attach a water hose to it. I did that last week.
It helped, except now the fleas are having a party in the pool. I guess they're trying to avoid the treated areas, so the pool was their only option. Now, how do I get rid of fleas in the pool? There are thousands, even MILLIONS of them in there! I'm not kidding.
I'm assuming it's a bad idea to spray permethrin in the pool?
