Mrmrezg, you are super fortunate that Major in Ms is around for tips because I just learned new tricks here to try and I've been battling the bees for a good few years!
The beekeeper across the road from me does not take the issue seriously at all - I did approach him about it this year and mentioned they seem to need a better water source. His theory is there "must be something they need in your pool." Then he gave me some honey to shut me up
Chlorine is like alcohol to them and salt is irresistible. Once they find you and communicate, you have a problem. Nonetheless, here are some tips I've used with varying degrees of minor success.
1. Hide pool noodles when not in use. This is their fav...color plus wet, chlorinated sponginess equals daiquiri to honeybees. I actually erected a tall cabinet to keep the noodles in. It helped forestall the "discovery" this year.
2. If you try the fountain/birdbath idea, place a sponge in it for them to and on...they don't like open water. And make sure you use the pool water...otherwise they'll bypass it and find the pool...which usually a few scouts will anyway.
3. Once a scout has found you, as sad as I am to say it, spray it with a mix of Dawn and water to kill it before it can share the news. Its the difference between killing one or having four dozen by the end of the day when there's a hive nearby. Early and consistent vigilance sounds cruel but is kinder in the long run.
4. An entomologist actually told me last year to beat the scouts to death violently, eg with a pool noodle, and that word would get back that we're hostile. We did give that a go, hated it, not entirely sure it worked but volume did reduce thereafter.
Avoid treating with Tempo as tough as it can be if you have folks with bee allergies around...the bees exposed could contaminate the hive.
They don't mean to sting but they can't really help it when they're trying to hang on to a noodle or raft and you move to purchase the same area. Odds of this spending increase with numbers.
I'm thinking about putting a water feature at front of house to waylay them next year, but have had a bee expert warn me that this may just draw more of them closer.
