So Florida has lots of frogs and toads that eat insects, and consequently, lots of snakes that eat frogs and toads. Because the snakes are so good at their job, there are plenty of insects left over for spiders, and Florida is loaded with them.
Spiders who build webs follow the common rule of Real Estate: location, location, location. Everybody wants a web that’s high enough that it won’t get torn up by passing animals, located right in the flight paths of big, juicy bugs, and has a high resale value, which means a view of the water.
This is why I have lots of spiders in my pool enclosure. In Florida, it’s best to enclose your pool in a screen house, to keep out the leaves, pine needles, frogs, toads, opossums and bugs. Pool enclosures are pretty effective at keeping everything out, but somehow, bugs still get in. They squeeze under the screen frame, they fly in when the door is open, they locate any small tears in the screens, and before you know it, they’re breeding in an enclosed environment that keeps out every natural predator except for two: spiders and me. I spray or swat at them with a broom, but they just laugh and fly away, right into the spider webs.
The corners of my screen enclosure are ideal sites for spiders to build webs to trap stray moths, dragonflies, mosquitoes and even other spiders. Some of them are beautiful, almost jewel-like.
I leave the spiders alone for the most part, until there are so many of them that the choice web sites are taken. The latecomers have to build their webs lower down, where I walk into them while vacuuming the pool. A few swipes with the broom and they’re gone for a month or so. If only I could get rid of my relatives that easily. I need bigger spiders.
