How many Small Hive Beetles (SHB) before I should be worried?
The other day I counted 22 small hive beetles (mostly dead, stuck in oil on a screened bottom board), after only 4 days.
I found 5 in a trap in my bottom deep box, none in a trap in my top medium box.
I had been seeing around 8 on average after a week or so – but 22 is a huge increase. At what point should I be worried, and what can I do besides traps and nematodes / diatomaceous earth around the hive?
