BUGS & INSECTS WE TREAT

7 common indoor and seasonal insects in Winnipeg

Some species breed indoors, while others gather on sunny walls and enter buildings to overwinter. Accurate identification determines whether treatment should focus on fabrics, wall voids, foundation entry points, outdoor lighting, or seasonal exclusion.

House cricket macro
NOCTURNAL CHIRPING PEST

House Cricket

Acheta domesticus
SIZE
16–22 mm
WHERE
Basements · garages · kitchens · utility rooms

Tan cricket with long antennae and strong hind legs. Warm indoor harbourage can support breeding, while males create persistent nighttime chirping.

Cluster fly macro
FALL OVERWINTERING FLY

Cluster Fly

Pollenia spp.
SIZE
8–10 mm
WHERE
Attics · windows · wall voids

Slow, dark flies that gather on sunny walls and enter attics to overwinter. They do not breed in garbage, but can emerge indoors on warm winter days.

Carpet beetle macro
FABRIC & STORED-GOOD PEST

Carpet Beetle

Anthrenus verbasci
SIZE
2–5 mm
WHERE
Carpets · closets · vents · window ledges

Small mottled adult beetles; the hairy larvae damage wool, feathers, natural fibers, and stored animal products in hidden undisturbed areas.

Ground beetle macro
ACCIDENTAL INDOOR BEETLE

Ground Beetle

Family Carabidae
SIZE
8–25 mm
WHERE
Basements · garages · door thresholds

Fast black beetles that normally hunt outdoors. They enter through ground-level gaps, especially after rain or when exterior lighting draws them toward doors.

Boxelder bug macro
SUNNY-WALL INVADER

Boxelder Bug

Boisea trivittata
SIZE
11–14 mm
WHERE
Siding · windows · south-facing walls

Black and red true bugs that gather on warm building surfaces in fall. Large groups enter wall voids to overwinter and reappear indoors in spring.

Lady beetle macro
OVERWINTERING LADY BEETLE

Lady Beetle

Harmonia axyridis
SIZE
5–8 mm
WHERE
Windows · attics · wall voids

Asian lady beetles vary from yellow to orange or red. They are beneficial outdoors but can invade buildings in large numbers and release a staining odor indoors.

Stink bug macro
ODOROUS SEASONAL INVADER

Stink Bug

Halyomorpha halys
SIZE
12–17 mm
WHERE
Windows · siding · attics · upper floors

Shield-shaped brown bug that seeks protected overwintering sites. When disturbed or crushed it releases a strong odor, making vacuum removal preferable.

WHAT TO WATCH FOR

Signs you need professional bug or insect extermination in Winnipeg

A few seasonal insects may be accidental visitors, but repeated activity, fabric damage, wall-void emergence, or large exterior gatherings indicate an entry or harbourage problem that should be identified before treatment.

OUR PROCESS

Our 4-step bug and insect extermination process in Winnipeg

Terra13 combines species identification, targeted treatment, and exclusion so seasonal invaders and indoor fabric pests are addressed at the correct source.

01

Identify

Confirm the species, life stage, activity source, and whether the issue is indoor breeding, fabric damage, or seasonal overwintering entry.

02

Locate

Inspect windows, vents, wall voids, attics, baseboards, fabric storage, foundation edges, lighting, and other insect pressure points.

03

Treat

Apply targeted interior, crack-and-crevice, fabric-zone, exterior perimeter, or entry-point treatment based on biology and risk.

04

Prevent

Provide sealing, cleaning, storage, lighting, and seasonal timing guidance so insects are less likely to return.

PREPARATION GUIDE

Bug and insect treatment prep — before & after we arrive

Preparation depends on the species. Carpet beetles require fabric access and cleaning; seasonal invaders require entry-point access; crickets and beetles require baseboard, basement, and utility-zone access.

Preparation Checklist

A printable one-page checklist covering access to windows, vents, basements, closets, fabric storage, pets, aquariums, and re-entry after indoor insect treatment. Your technician confirms the steps required for your species and service plan.

RE-ENTRY TIME

Everyone leaves 4–6 hours; 12–24 hours if asthma, allergies, pregnancy, or kids under 4.

BEFORE WE ARRIVE

  • Clear access to window frames, baseboards, closets, vents, and attic entries.
  • Move light furniture and storage away from affected walls.
  • Bag or isolate suspected infested fabrics until inspection.
  • Vacuum visible insects, larvae, shed skins, and debris before service.
  • Cover aquariums; remove people and pets as instructed.
  • Do not apply foggers or repellents before the technician arrives.

WHEN YOU RETURN

  • Ventilate and wipe food-contact surfaces when instructed.
  • Do not wash treated cracks, window frames, or baseboards early.
  • Launder or heat-dry approved fabrics after inspection guidance.
  • Vacuum visible insects and dispose of the bag outside.
  • Avoid foggers or repellents that can scatter insects into wall voids.

LOCAL CONDITIONS

Why seasonal insects enter Winnipeg homes and businesses

Winnipeg's long winter creates strong overwintering pressure. Cluster flies, boxelder bugs, lady beetles, and stink bugs gather on sun-warmed walls in late summer and fall, then move into attics and wall voids.

Carpet beetles and house crickets can persist indoors when food, warmth, and shelter are available. Ground beetles are usually accidental invaders, but repeated entry points to gaps, lighting, or drainage conditions around the building.

AFTERCARE

How to prevent bugs and insects from returning

Seasonal timing and exclusion matter as much as treatment. These steps reduce indoor harbourage and stop insects before they reach wall voids or stored materials.

  1. Seal window, siding, soffit, vent, and utility-line gaps before fall.
  2. Repair screens and install tight door sweeps at ground-level entries.
  3. Vacuum seasonal invaders instead of crushing odor-producing bugs.
  4. Store wool, feathers, and natural-fiber items clean and sealed.
  5. Reduce exterior lighting near doors or use warmer insect-reducing bulbs.
  6. Inspect attic windows, sunny walls, closets, vents, and stored fabrics seasonally.

House crickets, cluster flies, carpet beetles, ground beetles, boxelder bugs, lady beetles, and stink bugs. Identification determines whether interior treatment, fabric management, or exterior exclusion is most appropriate.

Many seasonal species enter wall voids and attics to overwinter. Sunny south- and west-facing walls, gaps around windows, vents, siding, and soffits are common entry areas.

Most inspections and targeted treatments take 60–90 minutes. Carpet beetle work or extensive attic and exterior treatment may require more time or follow-up.

Registered products are applied according to the label. During indoor application, people and pets leave and return only after the technician-approved interval and treated surfaces are dry.

Vacuuming is better. Crushing may release odor or staining fluids. Empty the vacuum outdoors and seal entry gaps to prevent replacement insects.

Treatment targets larvae, shed skins, lint, pet hair, dead insects, and infested natural-fiber materials. Cleaning and item-specific laundering or disposal are important parts of control.

Yes if exterior gaps remain or treatment misses the seasonal migration window. Terra13 combines perimeter treatment with exclusion guidance and confirms follow-up terms in writing.
