Our home is in a forested area and we were invaded by literally hundreds of spiders every year. After using this product according to directions, on the exterior only, our spider invasion has been cut by a minimum of 90%. And it is very easy to use. No pumping; it has a battery powered mechanical pump.

I am unsure as to whether it works or not. I am still have flea issues on my back patio and steps due to neighborhood animals.
