Not sure what kind of bees you have that can tunnel through brick, but I'm not sure I would mess with them. Ha ha.
Here in TN, Dad used to fight the carpenter bees at our house by cutting strips of old rubber tire inner tube about 3/8" wide and about 6 inches long. Then he would sneak up on the holes at night and double the inner tube strip and stuff it in the hole. The idea was that the adults couldn't chew through rubber to get in and cut more channel or lay more eggs and the new bees who hatched couldn't get out by chewing through the rubber. He waged the war for several years.
Maybe that would work with your "mason" bees.
These bees apparently chew into rafters and other exposed pine wood on the house and lay their eggs, then fill the channel with mud or "something brown." They resemble a bumble bee in size and shape and coloring, but Dad always said "They won't sting you, son!" I never put it to the test.
My method of dealing with carpenter bees was to take a tennis racket and swat them while they were flying by. They usually don't die, so you have to chase them down on the ground and stomp them.
Dad used to also tell me that there was "nothing under the house that would hurt me" when he sent me under there to pull a wire or adjust something. So far he was right about that.
holes in the ground
Carpenter bees do have venom. The only thing that distinguishes them from other bees is their habit of boring holes in wood to live.
Bumble bees live in small nests.
Bees can hide in several places. They hide in walls, on top of roofs, under houses and porches, sheds, and even in holes in the ground.
Bees collect four things:* Nectar, which they eat, also turn into honey. * Pollen, which is eaten, and fed to the larvae * Propolis, a resinous substance from trees, which they use to fill small holes in the hive. * Water. Bees, like all animals, need to drink. In hot weather they will regurgitate water and fan it with their wings to cool the hive.
Masonry bees are bees that build their homes in the cracks or holes in Brick,block, or stone buildings
it erodes the brick leaving small holes in the brick how does water cause weathering of a brick?
Does it absorb water? Does it have small holes in it? THINK!
Wasps, bumble bees and feral bees will often build their nests underground, sometimes utilising small holes that have been abandoned by small rodents
Plug the small holes with duct seal or if knockouts are missing fill the holes with knockout fillers.
No, but carpenter bees do.
the tiny holes on the bees abdomen for respiration
Most bumble bees live in suitable holes, such as abandoned mouse holes in the ground or in soil banks.
drainage
Bumble bees don't live in a hive. A hive is an artificial home for honey bees provided for them by a beekeeper. Bumble bees tend to live in small holes in the ground that have been vacated by rodents and adapted for their own use.
An air brick is a brick-sized block with holes embedded in a wall to allow ventilation through it.
Dirt Dobbers? These bees can be carpenter bees if they are making holes in the wood on your house. Mason bees use holes in trees usually made by woodpeckers, etc. You can make a mason bee house by drilling 1/4-3/8" holes in a thick board and placing on a tree or other structure. These bees are about half the size of a bumble bee. They are gentle.
