AGHHH! I think I have a similar problem... earlier this spring I moved a large garbage can and got swarmed by "bumble" bees... believe me they havd stingers... they stuck to my clothes biying me severaldozen times... I think we counted at least 50 bites from head to toe... found out I'm not allergic!! LOL... but it hurt for about a week... now they moved to a corner of the house... in a crack in the bricks... again.. I was cutting grass last evening about 3 pm... (I didn't know they were there)... and got swarmed... this times the tangled in my hair... I ended up at the ER... AGHHH! I heard you should wait until later in the day to try to get rid of them... as that's when the all go back to the nest... but... I will be doing my home work.. getting bitten is NO fun... and I have to get rid of them.. I don't want them to get inside... good luck...
