Just for the record, August in earwig month in Newfoundland. More and more of them are showing up under the top covers of my hives.
February 2019 Postscript: Earwigs are creepy and gross and I flick them out the hives when I see them, but they don’t hurt the bees.
We in central Utah, USA, get earwigs all over during the summer, especially coming into the house at sunset. We spray around the doors with slightly diluted white vinegar, nightly, to prevent it, and it seems to work fairly well. The vinegar would probably bother the bees as much as it does the earwigs, so perhaps that’s no help.
I’ve been seeing a ton of earwigs lately too, right on top of the inner cover. I always figured they were fairly harmless; I didn’t know that some of them eat larvae! The wasps are hanging around more lately too…
