If you have found wasps nesting in the wooden furniture in your yard, you might want to get rid of them. Here’s how to get rid of mason wasps and whether you need to do it at all!
Mason wasps are fascinating creatures that are known to build nests in tiny deep holes in wood and concrete using mud to create chambers.
These white and black wasps are extremely useful in controlling pests in your gardens and are considered good pollinators.
But unfortunately, people think that these wasps are responsible for destroying wooden furniture by carving holes to build a nest.
What if we tell you that it is totally wrong? Yes, mason wasps do not carve holes in furniture. This article will help you understand these wasps better:
Do Mason Wasps Eat Wood?
Sometimes you will come across several holes in your outdoor wooden furniture; these holes are the ideal spots for mason wasps to build their nest.
But you should know that these wasps don’t create these holes. Instead, they tend to occupy the pre-existing holes made carved by yellow jacket wasps, wood-boring beetles, etc.
This wasp species don’t chew wood to make paper nests. Instead, they are known to use mud to build their nest cells.
Mason wasps usually prefer to nest in holes that are about 1/8 inch in diameter. The holes are actually smaller than the wasp itself, and most of the time, they have to back out like a car reversing out of a parking spot.
The female wasps like to go deep into abandoned beetle holes to lay eggs. They hunt caterpillars or other insects to feed the larvae.
Do They Sting?
Mason wasps are capable of stinging but are usually less aggressive toward humans. These wasps are docile compared to other wasps, like a yellow jacket.
A mason wasp will only sting a human if they are provoked by one.
You should remember that a mason wasp is capable of delivering painful stings. Therefore you should be extremely cautious around them.
Are They Social? Do They Live in Colonies?
They are solitary wasps and use pre-existing wooden holes made by beetles and other wasps to make unique nests using mud. These nests look like pots in shape.
The females nest alone in deep old beetle holes where they construct a network of chambers with mud.
They lay the eggs in these chambers and later fill them with prey like leaf beetle larvae and caterpillars.
Once she has filled enough sections with eggs and food, she will cap off the nest’s entrance with mud.
Can They Get in Your House?
Mason wasps will not build a nest inside your house. They prefer to build nests outside, preferably in spaces like your garden or yards.
Also, since they don’t live in colonies, the nests are relatively small compared to other social wasps like the yellow jacket. Therefore it can be hard to track down these nests.
If you are looking to track a mason wasp nest, search in higher corners or edges of your house.
Are They Beneficial?
Adult mason wasps primarily depend on hunting and consuming other insects like caterpillars, cutworms, and more.
They are also known to feed on nectar. This indicates that mason wasps are good pest controllers and decent pollinators. Having them in your yard will keep unwanted pests away.
Can They Be Dangerous?
Though the chances of a mason wasp attacking a human are less, but you approach them with caution as they will sting if they feel highly threatened. The sting delivers a great of pain and causes swelling.
However, if large numbers of mason wasps build nests in the brick walls of your house, it could weaken the structural support of the building.
The nest-building process compromises the mortar in between the bricks. The nest-building process in wooden furniture also weakens the strength of the furniture.
How To Remove Them?
Since these wasps are beneficial insects, there is no need to remove them.
But if there are too many mason wasps flying around your house, you can drive them away by removing any wooden furniture in your yards.
If they are any wooden outdoor furniture, clean them and try to seal all existing holes using polyurethane or wood putty.
Wasp sprays can be used to kill these wasps, but since they are harmless, there is no need to use pesticides to kill them.
Simply seal the nests with wood putty to get rid of these wasps. If you face difficulties in spotting their nest, you can call pest management professionals to help you out.

You can also use polyurethane to cover these holes. The use of wasp spray will directly kill these wasps, which is unnecessary as they are harmless until highly provoked.
Are mason bees aggressive?
Masonry bees are non-aggressive compared to the other bee species.
They rarely sting and are known to lay their eggs inside existing tunnels or holes made by wood-boring beetles or yellow jacket wasps.
These bees won’t sting until and unless a human tries to manhandle them.

Mason wasps are beneficial insects and great pest controllers and pollinators.
Many people have the misunderstanding that they carve holes in wooden furniture, but they simply occupy the pre-existing holes and are known not to consume wood.
