Good afternoon,
I suspect my bees have a european wasp problem. I noticed a fair number of dead or dying bees near the entrance today, and a wasp in amongst the carnage.
The wasps aren't coming from my property, so I have no idea how to eradicate them, but I can install an entrance reducer.
I bought one to use, but it requires pieces to be screwed into the box. Is it possible to do this on a box that already has bees in it? It seems like it would be very upsetting to the colony to be drilling holes into their box, but I don't know how else to attach the reducer. I briefly tried duct taping it on, but it fell off less than a week later. Any advice?
Thank you in advance once again.
