How about bringing in snakes to eat the spiders? Or bats?Keep moving up the food chain until things even out!!!!!!!!!!!! Marc
Ann, I am wondering if your low voltage lights might actually be attracting the spiders. They love to build webs in good locations to catch flying insects. I know I have webs near my low voltage lights and there are also two huge toads that live around the lights for the same reason. I'll never forget the huge web that a spider made covering the top half of the opening of my sliding patio doors...My son was just a little guy and I would show him how the itsy bitsy spider went up the water spout...I wouldn't let my husband remove the web and we all walked carefully under it when we went outside...until the day I was in such a rush that I forgot all about itsy bitsy and ran right through the web....By the time I realized what I did...that huge spider was on my cheek crawling up my face! My husband still laughs about that! So far I haven't noticed any around my tub, but I don't have lights near the tub itself. Maybe if you turned off the lights, or blocked the solar collectors for a couple of days, you can tell if that is what is happening. Good luck and I would pick birds over pesticide any day!..Maybe you need a couple of chickens!
