I know them well. Realize that those swarms of little water bugs that are all over the surface near your dock are actually spiders. Get them under a microscope and you'll see! That is the best time to get them. Buy a pool cleaning net and scoop them up and crush them. It's amazing what this does to the population. I will also try the spider product mentioned earlier in this thread. But to answer the original question, never ever had a bite from them and, come to think of it, we have no mosquitoes!
