I've been doing a lot of trap-outs on trees and structures lately.
I have 14 working now and have taken 2 down in the last 3 days.
What I've noticed is I get a lot of bees but when I take the trap down and remove the plywood that sealed the entrance off, I'm seeing a lot of small hive beetle larva outside the hole but behind where the plywood was.
I've noticed a lot of small hive beetles in trees this year.
I believe what is happening is I trap the bees, the population drops and the hive beetle go rampant laying eggs.
They are so bad I won't release the bees in the hive to go back into the tree.
I'm just sealing it off.
Here is a picture of a tree that I took the trap down just yesterday.
All of the white is small hive beetle larva.
