Very high number of Bumbles Bees this year

I agree (but we are close neighbors). Will be interesting to hear if this is widespread and explanation.

That sounds like Carpenter Bees - we have hundreds on my property. The males stake out territories and go after any other bee invading its space. They look almost identical to the Eastern bumblebee, but have larger heads (they tend to burrow in wood). Carpenter bees tend to be solitary. Bumblebees will build a nest (sometimes in the ground) and can get quite defensive, they form small hives similar to honey bees.

Carpenter bees were up at our cabin last weekend (NE panhandle of WV). They do a lot of damage to the wood trim, and occasionally the logs. I tend to control them with a badminton racquet. Not efficient, but satisfying.

We here in western WV have both of them as well. Mostly the carpenter bees, but have seen the queen bumbles out as well. The carpenter bees don't know what to think about all the honey bees in my yard though. They get near a hive and they defend it well. I'm thinking about either a tennis racket for this season's carpenter bees as the badminton just isn't strong enough at times. lol

I have seen several around the hive in the backyard, but when they get near the front they don't stay very long! I had a hive last year though that I saw a Bumble bee fly in and back out of.

I have millions of carpenter bees at my place (well, maybe hundreds!), but very few bumble bees. I have always had an interest in the native pollinators, and came to the honeybees last! Apparently, the bumblebee population has struggled recently, and I just found a place that will sell a hive of bumblebees (including queen, etc.). Previously, you could buy a box of bumblebees for a single pollination season, but it was only workers and no queen.

I'm pretty sure the bees we are seeing are bumbles, we have a decent number of bumblebees around here in the summer, it was just a super high number of queens last weekend. I haven't seen any during this week though.

I did not know you could buy bumble bees! That's neat!

Any problem with Carpenter bees interfering in any way with honeybees? like will swarms avoid the area or anything like that.
