I asked this question once

Hello

  Ok i asked this once before about bumblebees entering my hives today i saw them going in the hives and the bees let them right in i did not thou see them come back out. The biggest hive let one in and it did not come out did the bees kill it inside or did they just let them comein and rob them the second hive did the same. Way are the guards leting them enter and not fighting them off the first hive is so busy working and the same with the second but they will not try the third hive.

Letting a bumble bee into the hive makes it easier for the bees to take care of the problem, it's harder for the bumble bee to get back out of the hive quickly and the bees in the hive can gang up on it, insuring the bumble bee is killed.

  I am glad to hear that but i don't know why they keep coming to my hives they are starting to be a pest they have alot of flowers to work just like my bees and it seems they are all coming from the same nest i have looked for it but have not found it yet.But when i do i am going to move them from around here i watch them and they come from the same direction every time.

use a entrance reducer, you don't have to use the small one just use one that block half the entrance and see if you still have this problem...

I found one of those giant bumble bees dead in one of my hives Sunday.

I like bumble bees.  It's hard not to like a bee...
