Do you have to spray Cyper WP directly on black widows or will this kill them by residual contact?
Last summer in NM, I had TONS of black widows appearing in my yard. When I say tons, I mean every 3 to 4 feet along the fence/flower beds there would be another BW. All the "over the counter" stuff found in stores said it would only work with direct contact of the spider, so I would spend many summer nights spotlighting and spraying these spiders. Will Cyper WP allow me to just spray the fence and flowerbeds without having to hunt these critters down at night or am I just destined to stalk these things forever.
Cyper WP will kill spiders and all other insects with its residual properties in addition to of course killing the spiders when applied on them as well. The spiders will die quicker if you happen to spray directly on them when applying the product, but the residual the spiders pick up after the product is dry will also kill them, it just may take a little longer.
