1. Pavement Ants
Pavement ants prefer to make their nests in soil without vegetation. Since it is often necessary to clear soil before pouring walkways, patios, or foundations, you will often find them alongside these concrete structures outdoors, hence their name. Pavement ants are not native to Canada. They originated in Europe but have been in North America since the 19th century. Pavement ants are most likely to make a nuisance of themselves by building large nests outside. They usually do not nest inside but may come inside to forage, especially during cold weather. You need to keep a watch for them because they can carry microbes on their bodies that can contaminate your food. Pavement ants are black or pale brown in colour. Their bodies are approximately 2 mm long. They have modified stingers that may be visible to the naked eye, but these appendages are not used to attack. Rather, they are used to secrete pheromones to leave trails behind for other ants to follow.2. Pharaoh Ants
Pharaoh ants are similar in size to pavement ants. You can tell them apart because Pharaoh ants are much lighter in colour, ranging from red to yellowish brown. Like the pavement ant, the Pharaoh ant is not native to North America. Unlike the pavement ant, the Pharaoh ant is more likely to nest indoors. It most likely originated from Africa, and therefore it needs a warm climate in which to nest. To survive in Canada, it needs to make nests in heated homes and will seek them out specifically. Once they get inside your home, Pharaoh ants can nest in places that you might not expect:- Electrical outlets
- Appliances
- Trash cans
- Linens
