Ants seem to be everywhere and nowhere at once. They seem to come from nowhere to take advance of every house-cleaning mistake you make.
But where are all of these ants coming from? How are ants entering your house?
Let’s study their points of entry…
Born In The House
Not what you wanted to hear, but some ants have always been in your house. In fact, they may have been born there! That’s right; some ant species can build nests inside your home – often using wall voids or rotting wood to make a nest. That means you could have several generations of these insects.
In truth, foraging ants in such a colony probably do go outside. Other members of the colony, such as those that tend to hatching eggs or the queen, may not.
Doors that are poorly sealed are ideal for ants to gain access. Check the seal along the bottom of the threshold, but also check for quality seals on the sides and the top of the door, too.
Check doors that are not used frequently too! Seals may deteriorate or cracks may develop unnoticed. These lapses can allow easy access for ants.
Cracks & Crevices
Actual cracks can invite ants inside your home. Some building materials – plaster and other building material can develop structural cracks that create a highway for these pests.
Seams of walls and windows as well as doors and vents are common locations for gaps and air exchange between the outside and inside of your home. These gaps are large enough for ants to find a path into your home. Look for these seams where a wall joins the floor, ceiling or corners. Also check areas where holes have been created in a wall for a window, outlet, or vent.
Toys & Other Articles
Ants may be brought into a house by mistake, too. For example, a hollow toy left in the backyard over summer can become host to an ant colony and then carried inside. They can also be brought inside on a variety of other articles, including furniture or appliances, storage tubs, and even groceries.
Foundation gaps & in the floor
Though most Australian home foundations are strong, they are not always airtight. These gaps can be created during construction and provide ants just enough space to enter a home.
What may not be so obvious is that ants can travel inside your floor! They may have established routes underneath carpets, tile and hardwood flooring. Finding their entry point into a room can be especially difficult if they are coming under the surface of a floor covering. This can include subfloors too!
When open, windows and screens with holes are an obvious entry for ants.
Beyond the window itself, the window frame may have gaps. The frames have the potential to collect moisture and the wood can rot, creating a home for several species of ants.
Check where your utility lines enter your home for ant activity. With all the electricity, telephone, cable, water and natural gas lines, there are a lot of little holes in your house for easy access.
