If you’re hearing a persistent buzzing around your property, you might be dealing with masonry bees. Known for their ability to burrow into mortar and other weak masonry, these bees can cause significant damage if left unattended. But fear notthere are effective and humane ways to address this issue. Lets explore some terrific solutions and dive into the problem in depth with tremendous technology at your disposal.

What Are Masonry Bees?
Masonry bees, also known as solitary bees, do not form hives like their honeybee counterparts. Instead, they excavate small tunnels in soft brick or mortar joints to lay their eggs. These bees are an important part of the ecosystem as pollinators but can become problematic when they damage your home.
Signs of Masonry Bee Infestation
Some signs include:
- Small holes in mortar or brick walls.
- Light powdery deposit near these holes.
- Increased bee activity around your walls, especially in spring.
Why Its Important to Address the Problem
Although masonry bees mean no harm to humans, their burrowing can weaken the structural integrity of your walls. Over time, these holes can expand and lead to expensive repairs. Its crucial to take proactive steps to protect your masonry.
Safe and Humane Methods to Get Rid of Masonry Bees
1. Locate the Source
Inspect your property to locate the holes where masonry bees are burrowing. These are typically small circular holes about the size of a pencil.
2. Block the Holes
Once youre sure the bees have left (usually in late fall), use a filler or mortar to seal the holes. This prevents future infestations.
3. Use a Bee Deterrent Spray
Natural bee deterrent sprays can be applied around the affected areas. These sprays are safe for the environment and discourage bees from returning.
4. Maintain Masonry with Regular Repairs
Cracked or weakened mortar is an open invitation for masonry bees. Regularly maintain your walls and fill any cracks you see. Learn more about the importance of maintaining your masonry walls by reading this guide on heat affecting masonry.
