Q. How do bees find the nesting holes?

Hole-nesting bees are naturally in search of nesting holes and as opportunists they nest in broken hollow branch ends, grub holes in dead trees and tree stumps, house sidings, and even the end of wind chimes.

Don’t worry, our spring mason bees and summer leafcutter bees are unable to create their own nesting holes and are simply finding existing nesting holes or spaces that are just the right size for them. Hole-nesting bees navigate by using their three simple eyes (called ocelli) on the top of their head to polarize sunlight. The polarized light can tell the bees their direction and time of day!

Hole-nesting bees approach the bee house and use their memory and sight first to hone in on their nesting hole. Inside the nesting hole, they use their sense of smell to verify it’s their nesting hole. You may find a bee go in and out of several nesting holes to see which is theirs!
