Alecia from Casper, Wy writes

Approximately how long will it take to kill spiders with Suspend SC?

I sprayed it directly on 2 hobo spiders and they seem unaffected by it


While Suspend SC offers a long lasting residual to keep killing insects even after it has dried it is not an immediate knockdown product. Suspend SC will take a few hours to kill spiders even if they are sprayed directly with the product. If you need something with an immediate knockdown you will need to use an aerosol pyrethrin spray such as 565 Plus XLO or Microcare.
