We have an 16' pool with an inflatable ring around edges. My bees are stinging the ring which is made of thin rubber. When my wife first told me this, I didn't think that the bees were capable of stinging through the ring. Every day or so we have to patch a hole in the ring and it has a bee stinger in it. We have found several dead bees in pool(one or two a day). I am working out of town now, so my wife is considering taking down pool, because she is getting tired of patching holes. Any suggestions????
