We have bats (serotine) in the loft, and while I was out at dusk watching for them to appear from the eaves, I noticed a few hornets buzzing around up there. Same again tonight, so I’m wondering if there’s a nest. Google just comes up with pest control companies telling me to kill anything that moves, but I’m generally okay with sharing my space! I find hornets quite fascinating and I spotted one buzzing around the pond yesterday. Just wondering if they might be causing any kind of damage to either the loft or the bats?
