German Cockroaches in Apartments: What Tenants and Landlords Can Do

Is it a German cockroach?

Health Canada describes the German cockroach as tan to light brown, about 1.3 to 1.6 cm long, with two dark parallel streaks behind the head. It cannot fly. Because cockroaches are mostly active at night, a problem can go unnoticed for some time.

A photo of the insect, even a squashed one, helps confirm the species before treatment. Other cockroaches found in Ontario can behave differently and may need a different plan.

Why one unit is rarely the whole story

Cockroaches move through the spaces that connect apartments: gaps around pipes and wiring, wall voids, shared laundry and garbage rooms. Health Canada notes they can be carried in on used furniture, food items, empty bottles and shipping cartons, and that once inside they travel quite easily.

That does not mean a neighbour is to blame, and it does not mean the home is dirty; Health Canada notes that cockroaches do not necessarily mean unclean conditions. It does mean that treating one kitchen while the units around it go unchecked often leads to the problem returning.

What tenants can do

• Report activity to your landlord or property manager in writing, with dates, rooms and photos.
• Keep food in sealed containers and take garbage out daily, as Health Canada recommends.
• Report leaks and condensation under sinks and around appliances.
• Follow the preparation checklist before the visit, including clearing the cupboards named in it.
• Avoid sprays, foggers and store-bought baits before the professional visit unless the technician agrees. Different products are not automatically compatible.
• Keep a dated log of sightings after treatment for the follow-up visit.

What landlords and property managers can do

• Arrange inspection of the reported unit and, where possible, the units beside, above and below it.
• Give tenants the notice required by the lease and Ontario's tenancy rules, along with the preparation instructions.
• Check shared spaces such as garbage rooms, laundry rooms and plumbing access points.
• Fix leaks and reduce clutter in storage areas you control.
• Schedule follow-up and keep a record of what was treated, what could not be accessed and what comes next.

Who arranges and pays for treatment?

Responsibilities for maintenance and repairs are set by your lease and Ontario's tenancy rules. If a landlord and tenant disagree about pest control, the Landlord and Tenant Board has information about rights, responsibilities and how disputes are resolved.

What a treatment visit looks like

A typical visit starts with an inspection of the kitchen, bathroom and other areas where activity is reported, then targeted gel baiting and crack-and-crevice treatment in the places cockroaches hide. Health Canada notes that cleaning and pesticides need to be used together, since pesticides alone will not succeed if conditions do not change. Our cockroach treatment includes free follow-up re-treatment, with the schedule confirmed before booking.
