Getting rid of bees in a brick wall involves either luring them out with a "trap out" method (using lemongrass or a one-way door) or physically removing the hive by carefully removing bricks to access and relocate or destroy the nest, often requiring a professional beekeeper or exterminator; never just seal the hole, as they will find another way out, potentially into your home. For small numbers, repellents like clove or vinegar might deter them, but a full hive needs more drastic action.
You can get wasp spray that is a thick foam almost like shaving cream. It coats the exit so that when they come out they get covered in which works better for enclosed nests. Spray it into the hole in the early morning or evening when most of the hive is in the next and less active due to the cooler temps.
Bees and wasps are repelled by the following plants, most of which have strong herb or mint smells:
You look for local bee removal services in your area. It's either going to be a beekeeper who will relocate them, or an exterminator who will kill them. Either way, it's probably going to involve cutting a chunk out of the wall from the outside.
Bees can survive for varying lengths of time when trapped in a wall, depending on the food supply, oxygen level, and temperature within the wall cavity. If they have stored enough food, a bee colony can live for months or even through the colder months.
In situations where bees get inside a wall or roof void however, smoking or trying to lure the bees out rarely works. Smoking bees in a structure usually makes it worse because it pushes the bees further into the structure, instead of driving them out.
To encourage the bees to leave, create a small smoky fire under the beehive. The bees will move once they smell smoke and likely never come back. Move away when you start the fire.
The "3 feet, 3 miles rule" is a beekeeping guideline for moving hives: move them less than 3 feet (so they find the new spot easily using landmarks and scent) or more than 3 miles (so they're forced to reorient to a completely new landscape). Moving them an intermediate distance (e.g., 50 feet to 2 miles) confuses forager bees, causing them to return to the old, empty location and get lost.
Bees nesting in chimneys, roofs, and walls can leave behind visible damage. Honey stains, crumbling plaster, and damaged paint are common aesthetic problems caused by honeybee colonies. Exposed brickwork in chimneys can also be compromised, leading to crumbling mortar and brick deterioration.
Neem, Mint, Citronella, Eucalyptus, and Cloves are some of the most common and effective ways to repel bees. They are easy to grow in pots and don't require a lot of maintenance. Bee repellents such as marigold and germanium can also be a very effective way to keep them at bay.

Signs of bees in the attic mirror those found in walls, such as noticeable buzzing, heightened bee activity, visible entry points, and stains or residue near entry areas. Unexplained dark stains or markings on your ceiling can also be signs of bees in the attic.
Sealing a hive inside the wall
The bees won't just disappear; they'll become trapped and desperate. This can lead to them finding new, unwelcome entry points into your home or even dying inside the structure, potentially causing foul odours and attracting other pests, creating new problems.
Some bees who were separated from the original colony might search for a new queen to start another colony. But, straggler bees can only survive for a week or two without the hive, and often they are not successful in starting a new colony.
Varroa Mites are the #1 enemy of honey bee and beekeepers around the world. These external parasites feed on the blood of adult honey bees, and reproduce on honey bee pupae. They can considerably weaken individual bees, and often vector viruses and other pathogens between bees.
Follow these October beekeeping tips to keep your bees safe and healthy and make the most of the fall season.
If you can't find a beekeeper to help, call a pest control company with experience with bee removal. Be aware that pest control companies generally will kill the bees before removing them. Don't try to remove the colony yourself unless you have experience and proper equipment.
"Do you know that...? - Old bees don't return to the hive in the evening? They spend the night on flowers, and if they have the chance to see another sunrise, they resume their activity by bringing pollen or nectar to the colony. They do this sensing that the end is near.
To remove the bees properly, the beekeeper must open the wall to remove the entire colony. If the outside wall is brick, it will require opening the wall from the inside. The bees may be vacuumed up and put in a hive body, or sections of comb may be placed in frames and then placed in a hive.
The strong odor of vinegar may help deter bees from returning to certain areas, encouraging them to relocate elsewhere. This is not really effective for larger, more established colonies.
Will honey bees leave on their own? The answer to this is usually NO. An established honey bee colony may swarm from a wall space, but this is their form of reproduction. Basically half the colony swarm off with the old queen leaving the other 50% of bees with a new untested queen.
A combination of garlic and white vinegar is also an excellent natural bee repellent. To make the garlic spray, place a couple of fresh garlic cloves in cooking oil and let them soak for a few days. The cheaper the quality of the vinegar, the more acidic it will be.
Beekeepers use smoke to keep bees calm during hive inspections or relocation. When bees sense danger, they release an alarm pheromone that alerts them to protect the hive. Smoking the hive masks that alarm pheromone and enables the safe removal of the colony.
Some suggest hanging dryer sheets around picnic areas or patios to keep these stinging insects away. While the scent might mask food odors and deter bees and wasps to some extent, it's not foolproof.
