Ants in Specific Walls

Ants in the Brick Wall
Ants infestation is a common problem under pavements and inside brick walls. They make their nests in the spaces between bricks. If you notice ant trails on the brick wall, take preventive measures before they establish their colonies. The best course of action is to seal all the potential cracks in your brick wall.
Ants in the Shower Wall | Bathroom Walls
As ants prefer to live near warm and moist surroundings such as bathrooms, near leaky showers, inside cracks near water pipelines, sinks, or under bathtubs. This is the best place for the ants to establish their colonies. Ants are attracted to shower walls due to moisture and warmth.
If you see ant trails in your bathroom you should first fix any leaky pipes, seal wall cracks, and keep your bathrooms dry and clean to prevent further ant colonization. After that use insecticide spray, dust or baits to exterminate ants from bathroom walls.

How to Get Rid of Ants in Walls: Step by Step Instructions
Ants are considered to be one of the most notorious pests. Small colonies of ants may go unnoticed but larger infestations of ants can lead to serious damage. Timely inspection and treatment can save you a lot of time and money. The eradication of larger ant infestation needs strict measures and an integrated pest management plan.
Step 1: Slowing Down the Ants
Ants are mostly attracted to your house due to the poor hygienic conditions, by following the food trails or in search of a safe shelter to avoid harsh weather outside.
Do not leave food leftovers overnight and take care of the cleanliness. Keep your bathrooms and kitchen area clean and dry. Fix all the broken pipes and seal the cracks and holes in the walls. As the wall voids and cracks are the most common nesting sites of ants. You can minimize the chances of ant infestation by applying these simple prevention tips.
However, if the infestation goes unnoticed at earlier stages then you may have to take strict measures to get rid of ants in the wall. Ants multiply rapidly and can develop their colonies in only a few days. The presence of ant trails or the piles of dust is the indication of an ant invasion in your walls.
Step 2: Inspection of the Infested Site
To effectively eradicate the ant colonies in the infested area or in wall voids you should identify what type of ant has infested your wall. There are thousands of ants species and each of them has different behavior and requires different chemicals.
Identify the ant species and investigate the level of infestation to devise an eradication plan. The next step is to select the best eradication method according to the ant type.
Step 3: Pest Control Methods
Liquid Sprays
The most common method to get rid of ants in the wall is with the use of liquid insecticide sprays. This is one of the most effective and efficient methods to eliminate ant invasion. There are multiple ant killer sprays are available commercially. You can buy the best one according to the type of ant species. The ant killer sprays usually common in two different varieties i.e. contact ant killer and non-repellent insecticide sprays (or residual ant killer).
The contact insecticide sprays instantly kill the ants when they come in contact with ants. This method may not be effective because it will only kill the ants present at the site and causes the remaining ants to move away.
Non-repellent ant killers do not repel the ants and act as an invisible deadly killer. It does not instantly kill the ants and allow them to travel back and to spread the insecticide in their nests.
Treat all the entry points, trails, and nesting sites with spray and follow the prevention tips to avoid the re-establishment of ant colonies. The following are some of the ant sprays that we recommend:

Insecticide Dusts
Insecticide powders or dust are in our opinion a lot more effective and versatile options than ant sprays. The spray can in some cases leave a stain on the wall and it is hard to apply it inside the cracks. On the other hand, with the use of the duster, insecticide dust can really reach deep inside the cracks and destroy the ants. The following are the best insecticide dusts that you can buy:

Ant Baits or Ant Traps
Ant baits or traps show the best results in comparison to other pest control methods. Baits are slow-acting but eventually are able to kill the entire colony (including the queen). There are different varieties of bait available commercially i.e. liquid baits, gel baits, and granular ant baits. They can either be protein-based or sugar-based baits, and you can buy them according to the eating behavior of the ant species that has infested your walls.
Some ants prefer sugar-based food whereas others like their food to be protein-based (greasy). Liquid baits are mostly sugar-based, less poisonous, and come in containers. Gel baits (mostly sugar-based) are sold in tubes or syringes, you can apply them on the surface near nesting sites. Granular ant baits on the other hand are mostly solid protein-based baits.
Put these baits near the wall voids, entry point, and at the ant trails. The ants will take the bait back to their colony and this whole process will eventually cause their death. You can also do a test with sample bait before application to check the effectiveness of the bait for the specific ant species. Do this in cases when you are not sure about the type of ant you are dealing with. The following are some of the best ant baits that we recommend:
Syngenta – Optigard Ant Bait Gel Box
Advance Select Granular Ant Bait
Homeplus Ant Killer Metal Bait Stations
How to Get Rid of Carpenter Ants in Your Walls?

The characteristics that distinguish pavement ants from odorous house ants are the presence of two frontal nodes at the abdomen with a cluster of hairs and two spines at the back.
Pavement ants prefer to build shelters in sidewalks, underfloor, in the wall voids or cracks, etc. You can apply sugar-based ant baits, ant traps, bait station, or liquid spray to get rid of pavement ants in walls or cracks.
Follow the trail of ants and inspect their entry points and shelters. After inspection, apply sprays or baits at the infested wall voids and pavements. Gel baits come with ready to use syringe or injection that you can squeeze directly inside wall voids or cracks. Seal the cracks after the treatment of infested sites to avoid their re-establishment.

How to Get Rid of Ants in the Walls Naturally?

Vinegar Spray
Prepare homemade liquid insecticide spray by mixing vinegar and water in equal parts (1:1). Pour the solution in a spray bottle and treat the trails, doorways, cracks and wall voids with the spray directly.
Peppermint Spray
Add a few drops of peppermint essential oil in water to prepare your insecticide spray. Apply the solution directly in the wall void, holes, and other nesting sites to get rid of ants.
Sugar and Borax Bait
You can prepare homemade sugar bait by mixing an equal amount of sugar and borax. Put the bait near the infested areas and on trails to eradicate ant colonies. You can also add honey or peanut butter in borax to prepare honey or peanut butter bait.
Soap Water Spray
To prepare soap water spray, add 1 part of dishwashing liquid soap in 2 parts of water and mix them. You can directly apply this insecticide spray on the walls and other infested sites.
How Can Ants Walk on Walls?
Ants are excellent climbers, they walk on the walls using tiny hooked claws which are located at the ends of their feet. The hooked claws help ants to cling to the wall. Ant can easily climb on smooth vertical or round surfaces.
However, they cannot walk on Fluon, a product similar to Teflon. This substance is too slippery for the ants to climb. Fluon can be applied on the wall or the pet feeders to keep the ants away.
Summary
Ants are easily attracted to the moist and warm environment and will build their shelters in narrow and dark spaces such as wall voids or cracks. Most of the ants do not cause structural damage in the walls but some species of ants (such as carpenter ants or moisture ants) can be extremely destructive for your wooden walls and other wooden structures. They excavate wood to build their shelter, but they do not eat or feed on the wood.
Keep your house dry, clean, and remove any excess water and damp wood that can lure ants. Mishandled ant invasion can lead to a larger infestation in only a few days. Carefully identify and inspect the infested sites to select the best insecticide for your specific type of ant that is causing you problems.
Several liquid ant killer sprays, ant baits, insecticide dusts, or sticky traps are available commercially which can help to eradicate any ant infestation. Natural insecticides also work similarly to synthetic ant killers but are not that effective.
