If I could rate it a ZERO I most definitely would have. It didn't even faze the spider. I sprayed so much it was completely white and only died by me stepping on it.

Terro products is good good decision for any insect problems in or around my home
I love this spray. My screen porch has spiders and ants and this stuff works great I use it regularly. I tried it on my carpenter ants. It slows them down but could use something more.

Can the spider spray be used on outdoor vinyl siding?
Question by: Charlene LeBeau on Oct 7, 2025, 11:57 AM
Yes, the water-based formula of our Spider Killer Spray is ideal for both indoor and outdoor use, including vinyl siding. We recommend testing the product in an inconspicuous area before full application. Spray until the surface is slightly wet, but avoid over-application to prevent potential damage. The product will not stain surfaces or fabrics where water alone causes no damage.
