How Do I Still Have Ants in Winter?

Ants are cold-blooded. In order to thrive and survive, they need an external source of warmth. Obviously, it gets considerably harder for ants to find these external sources in winter. Especially the ants that happen to live in Michigan. 

Despite the considerable adversity facing them each winter, ants are determined creatures. Subzero temperatures don’t stop their relentless drive to find food, shelter, and water. In order to find what they need this winter, ants will often attempt to infiltrate homes. Including your home, if you’re not careful. If you’re asking why you still have ants in winter, you’re in the right place. We’ll answer that question–along with how those ants got in and how to throw them out–below.

Why do I still have ants during the winter?

You have ants during the winter for the same reason you have them during spring, summer, or fall. Your home was easy to get inside and offered them the things they were looking for. If ants can’t find a home to infest, they’ll build their colonies and cluster under rocks, tree bark, decomposing leaves, or deep within the ground. If they can find a home, well… then there’s a problem. 

If they find a warm place (your house, for example) to nest in the winter, ants won’t need to cluster. They’ll instead be able to remain active throughout the entire year. Inside homes, they’re most commonly found inside walls, near pipes, inside molding, or under baseboards. They got inside by finding a breach in your home’s perimeter. It could have been crumbling brick, old boards, or a crack in the foundation.

What do they want?

Ants want what all common problem pests want: food, shelter, and water. If you’re reading this, it means you’re likely already facing an ant problem. That means they’ve already found one of the things they were looking for: shelter, warmth, and cover from the cold. That’s what brings them in. 

What makes ants stay after they get inside will be how well they can find food and water. Ants like sugar, fat, and protein-dense foods like meat, cheese, dried goods, peanut butter, baking materials, or pet food. Water is a less significant motivator since they require very little to sustain themselves. Ants are commonly found near hidden plumbing leaks because they like its easy, consistent moisture access. 

What can I do to prevent them?

That’s the most important question. If you don’t already have an ant problem, how can you prevent one from happening? Here are a few of our best ant exclusion tips:

  • Keep surfaces clean. Ants are scavengers. Their favorite places to find sustenance are on floors, garbage cans, and countertops. Keep dirty dishes out of the sink, wipe crumbs off the table, and mop residue off the floors.
  • Practice perimeter maintenance. Ants are tiny. It doesn’t take much for them to find a way inside your home. Just because it’s difficult to bar their entry doesn’t mean you shouldn’t try, however. Follow their trails to see where they’re coming in. Find perimeter breaches and fix them with caulk, putty, or plaster as needed.
  • Spot the scouts. If you ever see a lone ant, it’s a scout. Scout ants are sent out by the colony to find sources of food or water. You want to prevent it from having a chance to communicate with the nest about anything it may have found.

Winter is a surprisingly busy time when it comes to pest infestations. That’s because, like ants, many other pests are seeking shelter from the cold. If, despite your best efforts, one of those pests finds its way inside your home – give Griffin a call. Our experts can both help you remove existing pests and prevent future ones.

Do I Have Carpenter Ants?

Ants flying around inside your home may be the reproductive drones of a carpenter ant colony. Look for small, round excavation holes in wooden structures in your basement, crawl space, deck, or porch. Carpenter ants create these holes to discharge the sawdust-like wood shavings they produce while tunneling.

It can be frustratingly difficult to find conclusive signs that you have a carpenter ant problem. The ants tend to tunnel through deep or inaccessible sections of wood. Their tunnels tend to be impossible to spot until they start causing serious problems. By learning more about what ants are all about, however, you can be better at spotting them. This is what you should know about carpenter ants, including how to tell if you have them.

What are carpenter ants?

Carpenter ants (Camponotus spp.) are some of the largest and most common ants in Michigan. They’re also one of the most common home-invading pests in Michigan. Like other ants, carpenters live in large eusocial colonies where different castes perform different roles. Unlike most ants, colonies live inside wooden structures by hollowing them out from the inside. In the wild, they usually nest in decomposing trees, logs, or stumps. They can also tunnel through homes!   

Carpenter ant workers look like sugar ants, but they’re larger and have evenly-rounded thoraxes. Most workers are ¼ to ½” long. Carpenter ant drones are even larger, and they have flight-capable wings. Drones are often confused for termites, but you can tell them apart by looking at their antennae. Carpenter ants have distinctive “elbowed” (curving or “L-shaped”) antennae, whereas termites have straight, beaded antennae. You’ll probably see the ants crawling on or near wooden structures.

Why are carpenter ants a problem?

Contrary to popular belief, carpenter ants don’t actually eat wood. Carpenter ants tunnel through wooden structures to build large, complex “galleries” for their colony to live inside. As the colony grows, the ants continue to work their way deeper through the infested wood. In the meantime, the ants will continue to hollow out larger and larger segments of wood. Ant workers reduce the wood they tunnel through to a sawdust-like substance and transport it out of the colony. 

Obviously, hollowing out the inside of a wooden structure compromises its structural integrity. Over time, carpenter ants could seriously damage the wood they infest–and any structures that wood supports! If the ants hollow out enough wood, they could trigger the collapse of load-bearing structures such as support beams. Ant tunnels also tend to make wood more vulnerable to moisture accumulation and mold growth, which could lead to further problems.

Do I have carpenter ants?

The most obvious sign of a carpenter ant infestation is the presence of winged ants inside your home. If there are flying ants inside your home and it’s not mating season, then you probably have an infestation. Workers themselves may venture indoors during summer, but seeing them during winter is a bad sign. Look for workers around any exposed wooden structures, especially in naturally damp or humid parts of the home.

You should also look for small, circular openings on the surface of the wood. These holes are where worker ants expel the sawdust-like shavings they create when tunneling through the wood. If you find shavings or dust accumulating under these openings, your infestation is quite active. Remember: carpenter ants attack moist, humid, or damaged wood. If you’re worried you have an infestation, check wood that fits this description first.

What can I do about carpenter ants?

Tunneling through wood dries out carpenter ants very quickly. Workers require a constant source of moisture to re-hydrate if they’re going to remain active. For this reason, the ants almost exclusively target wet or moist wood. If they can re-hydrate while they tunnel, they’ll never have to stop working on their colony. By making sure wood around your home is dry, treated, and protected, you’ll keep ants from preying on it.

First, look for and fix possible plumbing leaks inside and outside. Make sure your outdoor gutters, downspouts, and drains are direct water away from your home effectively. Find places where wood contacts the ground and cover that wood with plastic sheets or barriers. Trim down branches, shrubs, or other “bridges” carpenter ants could use to access your home. Inside, dehumidify your basement, crawl spaces, and other lower levels as well as possible. Replace any damaged or soiled wood ASAP.

 

The faster you find a carpenter ant infestation, the more potential damage you can prevent. Watch for these signs of infestation, but look out for the vulnerabilities that may lead to infestations, as well. Protect wooden structures in your home, keep them dry, and watch for cracks and gaps ants could exploit.
