Q: What keeps the bees from going back out of the same hole they came in?

 

A: The holes on the side are drilled upwards at an angle and makes it more difficult for the bee to see the light from those once he is inside the wood looking to make a new nest. This is why the large hole is drilled leading to the jar. It allows more light in and the bee goes with instinct and takes the path of less resistance to escape.

 

Q: Where should I hang them?

 

A: At each corner of the structure that they have a presence in and at each corner of a wooden deck as well as at the eaves of a house.

 

Q: Do I need to put anything inside the jar to attract them?

 

A: Not necessarily. The bee is lazy. If they can find a hole that is already bored out, they will go for that hole. I use untreated pine to make my traps out of. Once one bee has gotten in and died, it puts off a pheromone that attracts other bees. If you put any attractant in the trap, it will attract other insects such as honey bees and mason bees which are great pollinators.
