I had zillions of spiders and webs all around my back porch, it was awful trying to clean them up without killing them. Spiders are good guys, I did not want to kill them but their habitats looked god-awful all around my sliding glass patio door. I read that bugs cannot see red light so, even though I did not want my porch in a red glow, I did not want it lightless either so I decided to try these. After a couple of weeks the spiders had moved on to better hunting grounds because no bugs or moths visited my porch anymore. Incidentally, I tried a yellow light recently but am so used to my porch cast in a warm glow the bright yellow glare was jarring - I've gone back to red. After more study I discovered that, yes, fewer bugs are drawn to yellow but some are - but none can even see red!
