Masonry Bees - Are They Dangerous?

Masnry Bee Control
Masonry Bees Are Often Confused With Wasps
Masonry Bees are reportedly responsible for many stings in Bristol and Bath each year, and we hear from our customers how these bees have stung them.

Yes it is true that stings from solitary bees are rare, but they do happen.

Casualties stung, reported that the stings were not left embedded in the skin like those of Honey Bees or that severe reactions to those bee stings had occurred.

It's because they sometimes nest close to the ground, in air-bricks and door frames that make them such a concern to property owners and parents of young children.

What Damage Do Masonry Bees Cause?

Masonry bees enter our homes through air-bricks, window vents, window frames, extractor vents, poor rendering and crumbling mortar between bricks and stone. You will also see them buzzing into the gaps between tiles.

Once embedded in a property they can create large tunnel systems or galleries in the fabric of the building, into which they lay eggs and prepare the next generation of bees.

These holes can then reduce the weather resistance of your home, leading to further weaknesses in the fabric of the building and more nesting opportunities for the bees next year.

How Are Masonry Bees Controlled?

For the most part, they can be controlled without pesticides, by filling and repairing any damage in late summer. The other method is pesticides that are injected into the brood chambers and entrances. This provides a very swift level of control.

Do Masonry Bees Need Controlling? 

If you have sting allergies, large populations damaging your building or have a fear of bees, then control is likely to be the only option available to you.

If the Masonry bees are in an outbuilding or in a place where they are not bothering you, then you could just as easily leave them to get on with things. The choice is yours.
