What is the difference between powder based and oil based insecticide?
I need to get rid of spiders in my house. I have tried burning lemon and lavender candles but they have gotten rid of all of them. I live in Albuquerque, NM
Folks tend to choose wettable powder formulations for spider control because they stay up on the surface of porous areas a bit better, they stick to the spider better and they are low to no odor. Wettable powder formulations such as Demon WP can leave a white powdery residue that can be noticeable on dark surfaces but it can be wiped away if needed. Oil formulations are not preferred for indoor use because they usually have high odor and can leave permanent oil stains on surfaces.
