We found Demon WP highly effective at killing bugs both indoors and outdoors. The powder dissolved quickly in the water. The gallon size allowed us to treat a large area in the yard and our home. One treatment went a long way. We were especially pleased that it eliminated box elder bugs too. It even controlled mosquitoes.
As we later learned, this particular class of insecticides is an alternative for controlling these pests to the now-banned DDT. One application handled the job completely. We are confident that it will do the same for you.
The residue is noticeable. We strongly advise you to follow the manufacturer’s recommendations regarding where to spray it. Clean-up was simple with no long-lasting effects. The fact that it is an EPA-approved product is also reassuring, especially given how well it performed.
Its low price tag and impressive residual effects are an excellent value that makes it a worthwhile purchase. The label spells out the correct usage clearly and straightforward, making it safe to use as directed. We also liked it that Demon WP works against many kinds of insects which adds another point in its favor.
