Demon WP Insecticide - Questions & Answers

You can spray all of your interior and exterior door frames, window frames and places where cables, pipes and wires enter through your walls with a good residual product such as Demon WP to help stop this pest from  entering your apartment.

Demon Wp is one of the strongest products still left on the market.  That being said it will not kill immediately once dry after a spider walks over it.  Spiders are especially hard to kill because their main bodies are up off of the ground and they do not groom their legs like other insects.  There is no product that will kill very quickly, within minutes, after it is dry.  Only contact kill products, aerosols mainly that are sprayed directly on a spider, like Raid, will kill it that fast.  Demon is still considered the best residual product for spiders.

You should thoroughly spray your lawn and water in the application with about a .25 in of water to help the bifenthrin get past the thatch layer and into the soil where grass hoppers actually develop. If you already have grasshoppers you can use Talstar P at the highest usage rate of 1 oz of product per 1 gallon of water for the quickest knockdown.
