Pharaoh Ant Control
in Toronto.
Pharaoh ant control in Toronto: identify tiny yellowish ants in kitchens and bathrooms, and why sprays can spread colonies in apartments and condos.
Understand what
you’re seeing.
Pharaoh ants are tiny, pale ants that live indoors in heated buildings. They are common in apartments, condos, hospitals and other multi-unit buildings, and they are known for being difficult to control with the wrong approach.
Identification & signs
- Workers are very small, about 2 mm, and pale yellow to light brown.
- Colonies nest in warm, hidden spaces: wall voids, behind baseboards, inside cabinets and near hot water pipes.
- A colony can have many queens. When disturbed, it can split into several new colonies, a behaviour called budding.
- In multi-unit buildings, activity often moves between units through shared walls and plumbing.
Identification reference: Health Canada: ants.
Practical first steps.
Start with the conditions you can observe. If the activity continues or the pest is uncertain, describe the pattern when requesting an assessment.
- Do not spray household insecticides or repellents on the ants. Disturbing the colony can cause it to split and spread.
- Record the rooms, especially kitchens and bathrooms, and whether activity is near pipes, outlets or cabinets.
- Keep food sealed and clean up sweet and greasy residues.
- If you rent or live in a condo, tell building management. Treating one unit alone may not resolve activity that is spreading through the building.

Pharaoh ants: common questions.
How do I know they are pharaoh ants and not another small ant?
Pharaoh ants are very small and light yellow to brownish, and they live indoors year-round in heated buildings. A close-up photo helps distinguish them from other small ants.
Why did the ants get worse after I sprayed?
Repellent sprays can make pharaoh ant colonies split into new colonies in different locations. Mention any products already used when you request help.
Do the neighbouring units need treatment too?
In apartments and condos, activity often involves more than one unit. Ask whether adjoining units or common areas should be inspected.
