Product Q&A

Answer:

Demon WP and Onslaught FastCap are both labeled for spiders. Demon WP does leave a white residue and once it gets washed off, it is no longer working. Onslaught FastCap will dry clear and leave a longer residual since once it is dry, it stays. The only problem with using any type of insecticide with spiders, is that they need to actually walk through it in order for it to kill them. You will need to spray the areas where they frequent, around doorways, corners of walls, etc.
