Query: Fantastic Stuff

I sprayed this spider killer around the perimiter of all three entrance doors to my home in the late afternoon. The following morning there were dead spiders of all sizes plus various other dead bugs scattered around my porches.I live way out in the country with thousands of irritating insects all summer.I really love this stuff, although, I do wish they made it in a concentrated style. It would be much cheaper to mix it with water & use my garden sprayer to apply it.
