Nestled in the heart of the Niagara Region, St. Catharines features a unique mix of residential neighbourhoods, parks, and nearby vineyards, creating a perfect habitat for ants to flourish. During the warmer seasons, common pests like carpenter ants and pavement ants often venture indoors seeking food, water, and shelter.
With St. Catharines experiencing cold winters and hot, humid summers, ants frequently move inside to escape harsh outdoor conditions. If left unchecked, these infestations can quickly grow and become challenging to control.
If you’re spotting ants in your home or business in St. Catharines, Abell Pest Control is here to provide expert assistance. Our local technicians carefully evaluate entry points, identify attractants, and implement safe, effective treatments designed to eradicate ants and protect your property from future invasions. We work year-round to keep your space pest-free.
The key to successful ant control lies in accurately identifying the species involved. Since different ants exhibit unique behaviors and nesting habits, precise identification enables us to customize treatments that deliver lasting results.
Carpenter Ants are wood-nesting insects that often invade homes seeking damp, decaying timber. Unlike termites, they don’t eat wood, they hollow it out to create nests. These ants usually target high-moisture zones like basements, under bathtubs, or behind window frames. They may enter through damaged wood, foundation cracks, or unsealed roof edges. Outside, they nest in logs or rotting trees; inside, they prefer wooden voids near water sources. Seeing these ants in your home, especially in the evening, may point to a hidden carpenter ant nest that needs prompt attention.
Citronella Ants (Large Yellow Ant)
The yellow ant, commonly referred to as the citronella ant, is found throughout Canada and the United States. It is recognized by its yellow to yellow-brown colour and the citrus-like odour it releases when crushed. These ants are non-aggressive and lack stingers. Yellow ants typically nest in moist environments, such as soil near building foundations, under logs, or in damp wood within homes. They do not feed on household food, relying instead on honeydew from underground insects. While not harmful to humans, their presence indoors can be a nuisance, especially when colonies are established. Swarming generally occurs during the warmer months, particularly in June and July.
Frequently found in cities and residential areas, pavement ants are small, dark-coloured ants that prefer to nest under concrete surfaces such as sidewalks, driveways, and foundation slabs. They enter buildings through tiny openings around windows, doors, and other structural gaps. Though generally harmless, they can bite or sting when provoked. Their long foraging trails are usually the first sign of a growing colony.
Pharaoh Ants are very small yellowish ants with darker tips on their bodies. They live in large colonies that contain multiple queens and multiply quickly through a process called budding. They often nest in warm, moist areas inside walls, kitchens, or bathrooms. Particularly common in apartment buildings, healthcare settings, and commercial kitchens, these ants can contaminate surfaces and food and are known to spread harmful bacteria.
Watch out for European fire ants in your garden or lawn! These aggressive ants hide in moist, shaded places, under rocks, in plant pots, or among garden debris. Their stings are incredibly painful and can cause lasting irritation, making them a serious pest in outdoor areas.
Known for their oversized heads, big-headed ants often make nests in the soil surrounding homes. They're typically found under pavers, near foundations, or hidden in decaying wood and yard debris. These ants don’t harm structures directly, but their large colonies can be incredibly difficult to eliminate once established. Though primarily outdoor dwellers, changes in moisture or temperature may drive them inside. They’re frequently encountered in subtropical climates around the world.
Which Types of Ants Are Commonly Found Inside Houses?
Several ant species often invade homes, including carpenter ants, pavement ants, and pharaoh ants. Carpenter ants create nests in damp or rotting wood, pavement ants build colonies in cracks in concrete or masonry, and pharaoh ants spread quickly in warm indoor environments. Correctly identifying the ant species is key to effective treatment and long-term prevention.
How Do I Know If There’s an Ant Problem in My House?
Signs of an indoor ant infestation include visible trails of ants (especially in kitchens and near baseboards), small piles of debris or sawdust near walls, and flying ants inside the home, which may indicate a mature colony. You might also see ants gathering around food, water, or garbage. If you're noticing these signs regularly, it’s time to consult a professional like Abell Pest Control.
Which Ant Species Are the Most Harmful or Dangerous?
While most household ants are more annoying than harmful, some pose bigger risks. Carpenter ants can damage wood structures by hollowing out areas for nesting. Fire ants can sting and cause serious allergic reactions. Pharaoh ants are known to carry and spread bacteria, making them a health concern, especially in hospitals and kitchens. Identifying the species helps determine the level of risk and the right solution.
How Can I Stop Ants from Getting into My Home?
Preventing ants starts with good sanitation and blocking access points. Store food in sealed containers, clean up crumbs and spills quickly, take out the trash regularly, and keep pet food areas clean. Check for and seal up small cracks or gaps around windows, doors, and your home’s foundation to stop ants from finding a way indoors.
How Can You Tell the Difference Between Carpenter Ants and Termites?
Carpenter ants are typically larger than most ants and are often confused with termites. The key difference is that termites consume wood, while carpenter ants chew through it to create nesting spaces. A licensed pest professional can help accurately identify whether you're dealing with ants or termites and recommend the right treatment.
Should I Hire a Pest Control Company for Ants or Try to Get Rid of Them Myself?
While DIY solutions might provide temporary relief, they often fail to solve the underlying issue. Ant colonies, which frequently nest deep inside walls or underground, can quickly come back without proper identification and treatment.
