Here’s Why Ants Suddenly Appear – 6 Reasons

Why Ants Suddenly Appear

If you know the behavior of ants and when they’re active, you won’t be surprised to see ants in your home suddenly.

Ants are nuisance bugs that carry pathogens, and some of the house ants bite too

When they transfer these pathogens to your food, you’re at the risk of catching salmonella, severe food poisoning. 

You’ll find out how to stop ants from entering your home in a minute, but for now, let’s find out why do ants suddenly appear in your home.

#1 – Ants Are Out Of Hibernation

It’s the most common, yet lesser-known, reason for the sudden appearance of ants in homes that many people don’t know about.

Have you ever wondered why ants suddenly disappear during winter? It’s because they hibernate. 

And they hibernate inside your home in the nests and colonies they’ve built when they’re active.

So, when ants come out of hibernation during the early spring, you see them everywhere in your home.

That’s a sign that there are active ant colonies inside your home, which you didn’t eliminate. 

And if you don’t destroy ant nests, then the sudden appearance of ants in your home will continue, year in and year out.

So, it’s critical to eliminate the ants’ nests while getting rid of ants in your home.

#2 – Your Yard Has A Massive Ant Infestation

Ants In Yard

Ants invade homes from the outdoors, especially when you’ve got a yard full of ants. 

It all begins with random ants with no ant trails scouting your home for food and moisture sources.

No matter what the species of ants is, be it pavement ants, fire ants, or sugar ants, ants will invade your yard first before they make a move towards your home. 

Your yard has a good enough habitat to harbor ants. Foliage, rotting pieces of wood, wastes in trash bins, and other bugs living in your yard are all there to sustain ants.

Things get worse when ants’ numbers increase. That’s when ants lookout for new places to hide and different food sources.

End result?

Ants invade your home. And there’s a sudden influx of ants in the form of ant trails inside your home.

And ants’ favorite place to invade in your home is your kitchen because that’s where food and moisture are. 

Hence, you see tiny black ants, and in worst cases, tiny red fire ants, in your kitchen scavenging for food. 

Chances are, ants have already built their nests in your kitchen because ants don’t stay far away from their food source. 

#3 – Weather Outdoors Becomes Too Hot

Like most living beings, ants, too, can’t handle extreme hot weather. When the temperature outdoors increases, sources of moisture and food run out at times.

That makes ants look for a milder place to live. 

And that’s why ants will sneak inside your home, looking for damp places where there’s enough moisture.

So, why do ants come into the house in summer? It’s because they’re looking for a damper and milder place to live. 

#4 – Ants Spillover From Your Neighbors

Like hibernation, this is also an underrated reason for the sudden appearance of ants in your home.

And that’s quite common in apartment blocks where pests like ants, bed bugs, and fleas spread to other apartments if one apartment has them.

In a neighborhood with an ant infestation problem, it’s normal to have many homes in the area to have an ant problem.

Ants will swiftly spread to other homes looking for new sources of food. And ants become quite widespread if homeowners in the neighborhood don’t get rid of ants in their homes.

#5 – Poor Garbage Disposal Systems

Pests and filth go hand in hand. One can’t exist without the other. 

Homes and neighborhoods with poor garbage disposal systems invite bugs like ants, roaches, flies, and mosquitoes.

Trash bins full of decaying food wastes, rotting pieces of wood and tree stumps, damp mulch beds, and decaying leaves are all responsible for drawing ants to your property.

Additionally, poor drainage systems with leaky pipes dampen the home’s floor and wall. 

That leads to damage to the walls and floors because of excessive moisture. 

Cracks develop, and those cracks become the entry points for ants in your home, and even worse, nesting places for ants.

So, shabby waste disposal systems and leaking pipes draw ants to your home. They also play a significant role for ants to suddenly appear in your home and property.

#6 – Ants Have Discovered Food Sources In Your Home

Random Ants In The House No Trail

Like most bugs, ants invade human homes for food and shelter. 

An abundant food supply in your home, especially in your kitchen, draws ants to your home.

The presence of ants in the kitchen, and home, also indicates that your kitchen is dirty and the food storage in your kitchen pantry is shabby.

Food spillovers food stains on kitchen countertops, stoves, ovens, and dishwashers, also play a role in attracting ants to your home. 

How Ants Enter Homes?

To stop ants from entering your home, you need to know the entry points for ants in your home.

And there’s only one standard way ants enter homes – through cracks and gaps.

Ants crawl inside your homes through the thinnest of gaps and tiniest of holes on your home’s walls, foundation, window frames, and door frames. They can also crawl in from under the door.

Vents in your HVAC systems, attic, bathroom, utility lines, and pipes are conduits for ants to move inside your home.

Apart from these entry points, you can also unintentionally bring in ants inside your home.

By bringing inside firewood, outdoor furniture, potted plants with ants, and any other stuff like boxes lying outdoors that have ants, you can introduce ants in your home. 

How To Stop Ants From Coming Into Your House?

Stop Ants From Coming Into House

To stop ants from coming into your home is easy. But you need to be a bit organized while following the steps you’re about to find out.

Here’s how to stop ants from coming into your house in six steps –

Step#1 – Seal The Entry Points For Ants

Begin with sealing the entry points of ants in your home. And these entry points are cracks and gaps in your home’s walls, foundation, windowsills, and doors.

If your home is old and the walls need repair, then do it. It’s because damaged walls are easily penetrable by ants.

Caulk the gaps on the windowsills, window frames, and door frames with a quality sealant. 

Use weather strips to seal the gaps between the window panels and window frames and close the gap between the door and the floor.

Ants crawl through these gaps, so it’s essential to close them. 

Most importantly, do not let any crack develop in your kitchen and bathroom walls and windows. 

The kitchen and bathroom are the go-to places for ants to infest and build their colonies. 

So, you must keep them clean and seal any cracks you come across in these two areas of your home.

Ants can also enter the home through the cracks in the gutters and roof. So, check for gaps in those places and seal them if you find any.

Step#2 – Control The Dampness Inside And Outside Your Home

Ants will suddenly appear in your home if there are sources of moisture that are making your home and property damp.

And those sources of moisture are leaky pipes. 

Check for water leakages inside your home. The plumbing area underneath sinks in the kitchen and bathroom has water leakage problems.

Check them out and fix water leakages if you find any.

Other damp places in your home are your bathroom, laundry room, and basement. These are prime real estate for ants. 

It’s because these places are damp, thanks to leaking pipes, and there are many bugs in these places for the ants to hunt. 

So, keep these places clean and dry by fixing any water leakage issues.

Don’t ignore your yard. If your yard is damp, then ants will be there too. And from there they’ll enter your home.

So, fix the water leakage issue in your yard too. Ensure that there are no waterholes in your yard.

Waterholes and old tires with stagnant water are a source of mosquitoes.

Plus, do not let trash bins in your yard store decaying food wastes and organic wastes for days. Keep discarding them often.

Else, they’ll attract not just ants but also flies and roaches.

Step #3 – Keep Your Yard Clean

A clean yard is critical for an ant and pest-free home. Apart from keeping your yard dry by fixing water leakages, you must keep it clean too.

Get rid of any foliage, rotting wood, and trash lying in your yard. If the mulch bed needs replacement, change it with mulch that repels bugs.

These things attract bugs that ants eat. And termites are one of them. 

So, if these organic wastes are in your yard, then there will be an entire food chain of bugs in your yard.

And many of them will invade your home too.

Check for ants’ nests in your yard. They’ll be in the form of little mud mounds in your yard and grass lawn.

Red fire ants’ nests are mud mounds without a crater or opening on the tip.

Other species of ants, like the carpenter ants’ mud mounds, have a crater at the tip. They use it to enter and exit the colony.

Pour boiling water in these mud mounds to destroy the ants’ nests in your yard and kill the ants living there.

Caution: Red fire ants are aggressive, and they severely bite and sting when their nests are under threat. So, wear protective clothing while pouring boiling water into their nests.

Spray an outdoor ant spray where you’ve noticed ant activities in your yard.

After spraying, move on to the next step to make your home’s perimeter impenetrable for ants.

Step#4 – Use Ant Granules Around Your Home’s Perimeter

Ant granules work wonders when it comes to stopping ants from entering your home. Ant granules also help in killing ants.

All you’ve to do is dig a ditch an inch and a half deep around the perimeter of your home’s foundation. 

Scatter the ant granules in the ditch around your home and pour water in the ant granules. In some brands of ant granules, you don’t need to pour water in them. 

These ant granules sink into the soil and kill ants hiding underneath the layer. They are also ant repellents, and they stop ants from sneaking inside your home. 

Remember, ant granules or any other insect granule is meant only for outdoor use.

Step#5 – Trim Any Overgrown Bushes And Chop Tree Branches Touching Your Home’s Roof

Another overlooked step that many homeowners fail to take is to trim overgrown bushes and shrubs around your home’s perimeter.

Ants use these bushes and plants to crawl up to your home’s windows and sneak inside your home through the cracks.

The same is the case with the tree branches touching the roofs and eaves of your home.

Ants in trees use these branches to crawl to the roofs and gutters. Then they use the cracks on these places to invade homes. 

Step#6 – Keep Your Home, Especially Your Kitchen Clean

And finally, to deter ants from entering is to keep your home and kitchen clean. 

Food spillovers, trash bins with food wastes, a poorly managed food pantry, and kitchen cabinets attract ants.

Ants feed on sugary stuff like syrups, jams, jelly, and sweets, along with foods rich in protein.

And if they’re lying around in your kitchen without proper storage, then your kitchen will be a haven for ants.

So, besides keeping your kitchen clean, store your food correctly. Keep your dry foods in tight airtight jars and containers.

Do not leave plates and utensils stained with food waste in your kitchen sink overnight.

That attracts ants and roaches.

Most of the time, ants invade the kitchen first. And from there, they spread to other areas of your home like your bedroom and bathroom.

Your bathroom can also be a favorite place for ants because it has enough dampness and wastes like broken hair and nails to eat.

When the infestation in the bathroom grows, then ants can sneak inside unlikely places like inside the cabinets and even in the toilet tank.

As a preventive step to keep ants away from your kitchen and home, use peppermint spray in your kitchen and other rooms of your home.

Ants and bugs hate the strong smell of peppermint spray , which keeps them away.
