I have two questions. I recently went out to just check on how my hives were doing by visually looking on the outside. I noticed two things! One was I noticed a lot of flies around one hive. I don't know if this is normal or not. Second, I also saw a lot of hive beetles actually flying around my hives. I have beetle blasters, as well as tarp that is underneath my hives (which I'm thinking about removing because no matter now tight I try to make it, water seems to collect under there) I spread lime around the hives on the ground (since it has rained it seemed to make it more compact to where bugs can walk freely over it) as well as salt and some salt in the grooves of the hive bodies. What else can be done besides an outside trap? Any suggestions would be great!
