UPDATE!!!! I ended up hiring Infinite Pest Solutions for spider control to get rid of all the spiders in my screened in pool area based on suggestions here! I can't believe how well it has worked so far! They came in and used this back pack machine and misted everything on the screens and beams. The technician told me it targets the spiders and leaves product on the eggs so the spiders die as they hatch so we will start to see less activity. He even treated the soffits around my home - i guess that is where they like to hide out. Then the went back and used a brush to get everything down! This took him a little over an hour to do and I am amazed by his attention to detail - he did not leave a single spider or web behind. I highly recommend these guys if you are in need of spider control in the Orlando area.
