Fast and effective!
I have been bitten by spiders a few times my life. I am not a person to mess with them. Knowing I have this spray to instantly kill the spiders puts me at ease, especially the jumping spiders which are hard to reach. The stream from the sprayer is wonderful and reaches far. This formula is not a strong scent. I do recommend this.

I sprayed on spiders around the outside of my house because they were weaving webs around my front porch. It killed them right away.

This was a straight shot. The spiders couldn't escape. Although I hated to get rid of them, I had to. This was a great help
