COCKROACH SPECIES WE TREAT

The 2 cockroach species we treat most across Winnipeg and Manitoba

Manitoba homes and businesses face two main cockroach species — German cockroaches in kitchens and apartments, and American cockroaches in basements and drains. Accurate ID drives the right treatment plan, the right products, and the right number of visits.

German cockroach
MOST COMMON IN WINNIPEG

German Cockroach

Blattella Germanica
SIZE
12–16 mm
WHERE
Kitchens · apartments · restaurants

Light brown to tan, with two dark parallel stripes behind the head. Fast-breeding — a single female can produce 30,000+ offspring per year. Lives in Winnipeg kitchens, bathrooms, and apartment walls, carrying asthma triggers and food-borne pathogens. Requires multiple visits with gel bait, IGRs, and harbourage sealing to break the breeding cycle.

American cockroach
BASEMENTS & SEWERS

American Cockroach

Periplaneta Americana
SIZE
35–50 mm
WHERE
Basements · drains · boiler rooms

The largest common cockroach — reddish-brown with a pale yellow figure-8 marking on the pronotum. Found in Winnipeg basements, drain stacks, steam tunnels, and commercial boiler rooms. Strong fliers in warm weather; prefers dark, damp infrastructure. Usually a single treatment plus a verification visit.

WHAT TO WATCH FOR

Signs you need professional cockroach extermination in Winnipeg

If you are seeing any of these warning signs, grocery-store sprays will only scatter the cockroach population and accelerate breeding. Call a licensed Winnipeg cockroach exterminator before the infestation spreads to neighbouring rooms — or in apartment buildings, neighbouring units.

Live cockroaches running for cover when lights turn on at night
A musty, oily, or almond-like smell in the kitchen
Pepper-like droppings near corners, cupboards, or under sinks
Shed skins near baseboards or behind the fridge and stove
Egg cases (oothecae) — small dark capsules in cracks or behind appliances
Greasy smear marks along walls and floor edges from droppings
OUR PROCESS

Our 4-step cockroach extermination process in Winnipeg

Every Terra13 cockroach treatment follows the same predictable sequence — free inspection first, affordable inspection-based quote, no surprises and no upsells.

01

Identify

Confirm the species (German vs American), locate harbourage zones, and grade the infestation. German cockroaches need a very different plan from American cockroaches — accurate ID drives a faster, cleaner kill.

02

Target

Non-repellent gel baits applied in cracks, voids, and harbourage zones where cockroaches feed and breed. Insect growth regulators (IGRs) interrupt the egg-and-nymph cycle so populations collapse instead of scattering.

03

Protect

Health Canada–approved, pet- and child-safe products. Applied only where they are needed — no fogging entire rooms, no lingering smell, no overspray.

04

Prevent

Seal entry points, advise on moisture control and food storage, schedule a verification visit with sticky traps. Free re-treatment within the warranty period if cockroaches return.

PREPARATION GUIDE

Cockroach extermination prep — pick your treatment method

Terra13 uses two cockroach treatment methods in Winnipeg — non-repellent gel baiting for typical German and American cockroach jobs, and residual spraying for heavier infestations. Download the prep PDF your technician will use so we can treat fast and safely on the day.

PDF METHOD 1 · GEL BAIT

Gel Bait Treatment Preparation Checklist

BEST FOR· Typical German & American cockroach jobs

Non-repellent gel bait placed inside cracks and harbourage zones. Bait stays active for weeks — prep focuses on keeping placements accessible and undisturbed so the colony cycles through the bait.

WHAT YOU'LL DO BEFORE WE ARRIVE

  • Clean kitchen surfaces, counters, and inside appliances
  • Empty cupboards, drawers, and under-sink storage
  • Pull fridge, stove, and dishwasher away from the wall
  • Remove pet food bowls and empty garbage before we arrive
  • Cover fish tanks and switch off air pumps during treatment
  • Do not use other sprays, foggers, or bleach before or after

Do not clean treated areas for at least 48 hours after we leave — the bait needs to stay accessible for the colony to feed on it.

PDF·1 page·1.03 MB·Updated June 2026
PDF METHOD 2 · RESIDUAL SPRAY

Residual Spray Treatment Preparation Checklist

BEST FOR· Heavier infestations & commercial kitchens

Crack-and-crevice residual spray applied where cockroaches travel and breed. Surfaces stay untouched longer for full residual effect, so the prep checklist is more thorough than the bait method.

WHAT YOU'LL DO BEFORE WE ARRIVE

  • Remove everything from cabinets, drawers, and countertops
  • Bag food, dishes, and utensils in sealed plastic or containers
  • Pull appliances away from the wall — fridge, stove, dishwasher
  • Clear under-sink storage and bathroom cabinets of personal items
  • Vacuum thoroughly and reduce cardboard / clutter beforehand
  • Keep pets, children, and fish tanks away during the visit

Do not wash or bleach treated surfaces for 14–21 days. Re-entry is typically 4–6 hours after we leave, or as your technician specifies.

LOCAL CONDITIONS

Why Winnipeg apartments, restaurants & basements get cockroaches

Winnipeg's apartment density, shared utility chases, and active food-service scene make German cockroach activity persistent year-round. They travel between units through wall voids and shared plumbing — and hitch in on grocery bags, used appliances, and cardboard from outside.

American cockroaches concentrate in older Winnipeg basements, sewer-connected floor drains, and downtown buildings with steam tunnels. Warm, damp infrastructure is the breeding signal — fix the moisture, kill the colony, keep them out for good.

AFTERCARE

How to prevent cockroaches from coming back to your Winnipeg home

Cockroach extermination kills the colony. These habits stop the next one from moving in — especially important for German cockroaches that re-enter through shared walls and grocery bags.

  1. Empty kitchen trash daily — cockroaches need food, water, and harbourage to survive.
  2. Store all food (including pet food) in sealed glass or hard-plastic containers.
  3. Fix leaky taps, slow drains, and dripping pipes — water is the limiting factor for cockroaches.
  4. Vacuum behind appliances weekly — fridge, stove, and dishwasher edges harbour eggs.
  5. Inspect grocery bags, cardboard, and used appliances before bringing them indoors.
  6. Seal cracks around baseboards, plumbing penetrations, and electrical outlets.

FAQ

Cockroach extermination Winnipeg — frequently asked questions.

Can't find your answer? Call us any time — we'll pick up.

Pricing is affordable and based on inspection findings, pest activity, access, and treatment scope. We confirm the recommendation before work begins.

Yes. Terra13 runs a 24/7 emergency line for active cockroach infestations across Winnipeg — same-day arrival is available for most addresses inside the perimeter. Call +1 204-881-5849 and we will triage the species over the phone before we arrive.

A typical cockroach extermination visit in Winnipeg takes 60–120 minutes on-site. German cockroach jobs usually need 2–3 visits over 6–8 weeks to break the breeding cycle. American cockroaches are usually one visit plus a verification check.

Yes. We use Health Canada–approved gel baits and dusts, applied inside cracks, voids, and harbourage — not surfaces pets or children touch. Re-entry is usually immediate once placements have set.

No. Cockroach extermination doesn't require evacuation. We may ask you to keep pets in another room for about an hour while bait gels and crack-and-crevice treatments set.

Free re-treatment within the warranty period — typically 90 days for American cockroach jobs and up to 6 months for German cockroach infestations (the longer cycle accounts for the egg-hatch verification window).

We can, but for German cockroaches in apartment buildings we strongly recommend treating adjacent units too — they travel through wall voids and shared plumbing. We will inspect the building footprint at no extra cost.
