Ants take advantage of their tiny bodies and sneak through small spaces in the electrical devices without problems. They usually cross barriers to reach a food source and can reach air conditioners when looking for a slightly cold environment.
Why Are There Ants In My Air Conditioner? Ants can get inside an air conditioner due to hot weather, electrical circuits, small holes or spaces, dirt and debris, and water sources. You can get rid of them by putting liquid ant baits, spreading chalk powder and peppermint flakes, and removing their nests. Avoid dumping leaf litter close to the AC unit and clean the unit with soapy water to remove their odor trails.
Ants can damage their internal components by chewing the wires. Interference with the electric wires can be deadly for them, leading to the accumulation of dead insects in the unit that can cause a short circuit.
Why do ants get inside an air conditioner?
Ants can get inside small holes present in walls and other objects if they are looking for something inside it. Their purpose is to reach a safe place with food sources and water.
Due to the hot weather
You can see ants around the AC unit when the external temperature is too high for their small bodies to tolerate. These cold-blooded insects face problems related to survival.
A significant increase in their body temperature is deadly for them because their foraging patterns change. Similarly, their activity rate decreases when it is too hot for them to perform any activity.
Accordingly, they look for cool places to lower their body temperature and get closer to the air conditioner. The cool air of AC keeps them cool in summer when it is hot outside.
They find cool places inside the house and begin to move toward it because such places can provide a temporary shelter to survive the summer season.
Electrical circuits
They are attracted to electric current sources because they can detect electrical fields. They detect warmth in electrical outlets and sense the field that can potentially allure them.
The tawny crazy ants are usually drawn to the electrical outlets and other electrical devices. They can detect the electric field and relate it to the presence of food sources.
They begin to move toward an electrical field that can be deadly, but they are unaware of the possible danger. It can lead to the death of ants after a severe shock.
However, the presence of dead ants in the electrical circuit of AC attracts more of these insects because dead ones release chemicals to attract other fellows.
Small holes or spaces
Ants are small enough to get inside the small spaces within an AC unit and live inside it. They find it safe to live within narrow and dark spots where other larger predators cannot reach.
Accordingly, they get attracted to AC units due to the presence of small holes within these units, which provide a safe place to live. Commonly, people shut down air conditioners when the winter season approaches.
These insects spend winter in warm places, so they get inside this device to avoid exposure to cold air. It provides an ideal environment and a warm or dark place for these insects.
One of my friends told me about an ants infestation in the air conditioner at his home, which happens every year in winter. So, he figured out the possible reasons for their entries.
Now, he makes sure to clean, dry, and cover the small spaces within the unit before winter to help avoid entries of undesired creatures.
Dirt and debris
Lack of maintenance can make AC units attractive to small insects because dirt and debris make them feel at home. Similarly, ants reach inside if they find it dirty due to less frequent cleaning.
Poor cleaning practices and lack of attention to accumulated dirt attract ants because they like to live in soil and debris.
You have to deal with severe ant problems if you do not clean the unit frequently. The filters get dusty or dirty, and mold grows on the vents over time.
In addition, these devices give off a pungent smell when the mold grows in an uncontrollable manner and dust accumulates on the filters.
So, you should keep them clean and regularly maintain the internal components to avoid the smell that can be enticing for these insects.
Seek water
These are moisture-loving creatures and get attracted to humid and moist places. They also reach an AC unit, or particularly the drain pan, which provides a source of moisture to them.
A leakage in the condensation drainage system provides a water source for these tiny insects. An outdoor AC unit can draw ants if raindrops are present on it.
I have observed the presence of tiny black-colored ants on my outdoor unit of AC after rain that are probably finding it attractive due to the presence of raindrops.
How do I get rid of ants in my air conditioner?
Some chemical and natural methods are available to deter ants from your property, and electrical devices are present inside the house with excellent efficiency.
Put liquid ant baits
The use of liquid ant baits to remove ants is common among people because it helps avoid the mess of spreading powdery substances and the use of toxic chemical sprays.
You can put a few sugar bait stations close to the infestation and wait for them to come out of the air conditioner. They leave the AC unit and begin to move toward the food source.
At this time, you can kill them by drowning in water and vinegar solution. This method takes time to kill these insects but provides a long-term benefit regarding their removal.
Sprinkle chalk powder
Using chalk powder is an effective solution to an ant problem because it helps deter these insects. Make a boundary of chalk powder around the AC unit by spreading it around the unit.
They do not like the odor of chalk and try to remain away to avoid disruption of pheromone trails. The powder covers bodies when they try to cross the chalk line, resulting in a loss of direction.
Sprinkle peppermint flakes
They do not like the odor of peppermint, so you can use it to repel these insects from the desired spot. Spread dry peppermint flakes close to the air conditioner unit.
It creates a field of aroma in the periphery and deters the insects from trying to get closer or inside by sneaking through small spaces.
Clean with soapy water
It is good to keep the air conditioner clean by washing its filter and cleaning the outdoor unit. You can use soapy water to remove the dead ants and their trails from the AC.
Dead ants are usually responsible for attracting more fellows because they can detect oleic acid secretions from dead insects. It helps prevent future infestations when their trails are wiped out.
Do not pour soapy solution directly over the unit to avoid damage to its internal components. It is better to spray or sprinkle the solution on the outer surface of the unit.
Avoid dumping waste close to the AC unit
Many people do not bother dumping waste material like leaf litter close to the AC unit outdoors. This organic waste invites many decomposing insects due to its stinking odor.
Accordingly, ants can also reach there and move inside the unit if it is present at a close distance. The carpenter ants, harvester ants, and leafcutter ants reach the organic waste for decomposition.
They obtain nutrition from the decaying organic matter and nourish themselves. So, you have to avoid dumping waste close to the unit to prevent their infestation within it.
