Hello,
I’m wondering if I can spray the foundation & perimeter of my house for Spiders – using Deltamethrin or LAMDA-CYHALOTHRIN and spray the same areas with Conquer EC.

Is it OK to spray over one insecticide with another? I have problems with Spiders and Camelback Crickets and I’d like to know if I can use both before I buy the products.
Thank you.
