    No GOOD!

    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.

    When cold weather sets in the insect invasion skyrockets; not so this year. In the days following our use of this product we found many dead spiders and other insects near the front stoop and side door patio. Not sure how long it remains effective so we are spraying weekly until we get a severe frost.

    Outside porch area was always covered with spiders. Regular pest sprays only stunned them for a short time. While spraying with this they started falling and dying immediately. The really large ones crawled away but died within 15 minutes. Two weeks later I am still able to enjoy being outside. The spiders haven't recovered.
