Cockroaches Overview

Resilient nocturnal survivors that contaminate food, trigger allergies, and spread pathogens. Among the most difficult pests to eliminate without professional intervention.

Indentification

Flat, oval body; long antennae; six spiny legs; German Cockroach is 12–15mm, light brown with two dark stripes behind the head.

Primary Diet

Very fast — German Cockroach produces a new generation every 60 days

Breeding

Omnivorous scavengers — food scraps, grease, paper, glue, soap

The Pest That Survives Everything — Except the Right Treatment

Cockroaches are among the most ancient and adaptable insects on Earth, and among the most dreaded in a home or commercial kitchen. In the Lower Mainland, German Cockroaches are the most commonly encountered species — small, fast-breeding, and extraordinarily resistant to many common pesticides. A single egg case can produce up to 40 nymphs, and populations can double within weeks under favourable conditions.

Pro Insight

German Cockroaches have developed resistance to many common insecticides. Rotation of active ingredients and bait placement science are critical — amateurs using the wrong products can trigger “bait aversion,” making populations significantly harder to treat.

Safety Rating

Gel Bait & Insect Growth Regulator Treatment (Low-toxicity, targeted application)

Prevention Tip

Cockroaches travel between units in multi-family buildings through plumbing and electrical conduits. Seal gaps around all pipes under sinks and behind appliances, and never leave dishes or standing water overnight.

DIY Risks

Consumer sprays repel cockroaches rather than killing the population, causing them to scatter and hide deeper. This spreads the infestation and makes professional treatment more complex and costly.

RainCity Advantage

RainCity uses pharmaceutical-grade gel baits combined with Insect Growth Regulators (IGRs) that sterilise surviving adults, breaking the breeding cycle and preventing re-infestation.

Outcome

Significant population reduction within 1–2 weeks; full elimination typically achieved within 2–3 treatment visits.

Control Method

Targeted gel bait application in harbourage zones combined with IGR treatment, crack-and-crevice injection, and monitoring stations.

Noise & Disruption
Cockroach droppings, shed skins, and saliva are potent allergens linked to asthma attacks, especially in children. They spread Salmonella, E. coli, and over 30 other pathogens across food preparation surfaces.
Cockroaches contaminate food stores and can damage paper, fabric, and book bindings. Large infestations produce a pervasive musty odour that can penetrate walls and cabinetry.
Seeing cockroaches — particularly during the day — is deeply distressing. In commercial kitchens, a single sighting can trigger a health inspection, closure, and reputational damage.

Signs of Activity

Early detection prevents small issues from becoming full infestations. Watch for signs in hidden or undisturbed areas.

  • Droppings

    Small dark droppings resembling ground pepper or coffee grounds found in kitchen drawers, behind appliances, and along the tops of cabinets.

  • Egg Cases (Oothecae)

    Brown, capsule-shaped egg cases roughly 6–9mm long found in hidden areas behind appliances, inside cabinets, or along wall junctions.

  • Musty Odour

    A distinctive, oily, musty smell in the kitchen or bathroom that intensifies with larger infestations — produced by cockroach pheromones and droppings.

  • Daytime Sightings

    Cockroaches are nocturnal. Seeing them during the day indicates a severely overcrowded infestation where competition for harbourage has forced individuals into the open.

  • Smear Marks

    Dark, irregular smear marks along wall junctions, behind appliances, and near moisture sources where cockroaches regularly travel.

Frequently Asked Questions

Find expert answers to our most common questions and discover how we keep your home or business pest-free.

Possibly. Cockroaches are nocturnal and highly secretive — if you see one during the day, there are almost certainly many more hiding. A thorough inspection is strongly recommended.

Yes. In apartments and condos, cockroaches frequently spread between units through shared plumbing chases, electrical conduits, and gaps in walls. Treatment of adjacent units is often necessary for full elimination.

Yes. Cockroach allergens are a leading trigger of childhood asthma. They also spread bacteria including Salmonella and E. coli across food preparation surfaces as they forage.

Consumer sprays are repellent — they scatter cockroaches rather than eliminating the population. Many populations have also developed resistance to common active ingredients, making professional-grade baits and IGRs essential.

German Cockroaches can go from a handful of individuals to thousands within two to three months. Early intervention is critical to prevent an infestation from becoming deeply embedded.

For gel bait treatments, no evacuation is typically required. RainCity will advise on any preparation steps and re-entry times based on the specific products used.
