We would recommend Bifen IT as a great general insecticide. It is labeled for spiders, roaches, and over 75 other pests. It can be used indoors and outdoors. The residual is up to 90 days indoors and 30 days outdoors. Bifen IT can also be broadcast across your lawn, sprayed on trees, shrubs, flowers, etc with a hand pump sprayer. It cannot be sprayed on any type of edibles. You will mix 1 fl. oz. of Bifen IT per gallon of water.
