Who knows what this thingy is.

Winner/Winner Chicken Dinner. It is a wood boring bumble bee trap. And it works. Anyone ever been around a old barn has seen these Bumble Bees flying around. But they are so lazy they look for a hole that has already been drilled.

I will be filing a grievance, because technically a Bee is an "insect"....I think I should have the illusive "chicken dinner"

Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the European honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea and are presently considered a clade, called Anthophila.

OK everyone gets a trophy  and a chicken dinner,

Those darn bees are always digging holes in my soffits.

These traps really work, you should get one, I did see a version of this at Lowes.

What is on the inside?  How does it keep the bee from just going back outside?

Don't think of it as a "trap" as much as an "easy" nest for the queen to start off in.  Catch her and you will have a fantastic tomato harvest that year!

Apparently they are not too bright, once they fall into the jar they cannot find their way back out. I have caught around 10 this year. The rascals were drilling into the wood on my small shop. Looks like you drilled 1/2" holes all in it.

Looks like a birdhouse with a septic system attached...

I have a sh!t load of those m'er f'ers around our pool - the deck is slowly rotting away and, while those bees typically don't prefer treated woods, I believe the "treated" aspect of the decking has expired, and it must now be delicious or something...  Anyways, I have 2 of these traps hanging near their nests and while I have dozens of them captured, I still keep getting more.

Sidebar, while you can get some fancy smoke to pump into the existing nests to kill them, I've found that a little brake cleaner does a helluva job as well... 

(Oh and also sidebar, it's a rental property, thus why I haven't replaced the deck...)

I have done the same thing, WD-40 works good as well, spray it in the hole and it sounds like a Mopar cranking up. Also they dont like painted wood.
