Question on egg sacs, not so much species. Have Southern black widows and wolfies in my garage. Have egg sacs I can't reach with vacuum - how long do I have before they hatch? Is Isoropyl alcohol the same thing as Web-out (if so 70% or 91%) or should I go straight to Talstar for egg-sacs? What's the best option short of exterminator or flame thrower? I had a lizard keeping them under control but he hitched a ride on my car and flew off at 60.
