Contaminates food, carries more than 30 pathogenic bacteria (e. coli, salmonella, staphylococcus), causes allergies and asthma in exposed children, defect classified as a major infestation in restaurants.
Nova Extermination treats the German cockroach (Blattella germanica) on the South Shore of Montreal, with a protocol adapted to the biological cycle of the species and a guarantee adapted to the case. License RBQ 5734 75930 01.
How to recognize the German cockroach
Correctly identifying the pest is the first step in a long-lasting treatment. Incorrect identification, for example confusing German cockroach and oriental cockroach or confusing native ladybug and Asian ladybug, leads to inappropriate treatment and recurrence within a few weeks. If you are hesitating, compare it with our fact sheet on cockroach extermination or send us a photo by text at 514 666 6682.
Quick Identification Sheet
| Small in appearance | , 1-1.5 cm as an adult, pale brown with two dark longitudinal bands behind the head |
| Preferred habitat | hides during the day, goes out at night, prefers warm and humid areas (kitchens, bathrooms, behind appliances, in cracks in countertops) |
| Ultra-fast life cycle: a female produces about 30 nymphs every 3 to 4 weeks, up to 6 litters in her lifetime, which means that the population doubles every month without treatment | |
| Typical damage | contaminates food, carries more than 30 pathogenic bacteria (E. coli, salmonella, staphylococcus), causes allergies and asthma in exposed children, defect classified as a major infestation in restaurants |
Store a dead specimen in a closed plastic bag if possible. Our technician confirms the species at the beginning of the visit, which determines the protocol and duration of the treatment.
Signs of an active infestation
- Presence of live individuals during the day (usually a sign of an established infestation)
- Moulting, exuviae or corpses found in the nooks and crannies
- Eggs or egg capsules (for cockroaches, mealworms)
- Persistent characteristic smell (cockroaches, bedbugs)
- Traces of droppings on storage areas
- For biters (mosquitoes, bedbugs): recent skin marks on occupants
The earlier the diagnosis, the less treatment costs. An infestation detected in 5 individuals can be treated in 1 visit. With 50 individuals, count 2 to 3 visits.
Life cycle and spread
Ultra-fast cycle: a female produces about 30 nymphs every 3 to 4 weeks, up to 6 litters in her lifetime, which means that the population doubles every month without treatment.
Understanding this cycle is essential: a treatment that covers only adults (e.g. a surface sprayer) leaves the eggs intact. Two weeks later, the infestation resumed. Our protocol covers THE entire incubation period, which explains the follow-up visit provided for in the package.
Our treatment method
Long-acting attractant gel applied in cracks and passage points (more effective than the sprayer, which disperses the colony), inspection of appliances, coordinated treatment with condo neighbours.
Total duration: initial treatment 1 h, follow-up at 14 days, final control at 6 weeks.
Why we avoid aggressive spraying
A wide spray may seem effective, but it disperses the colony to other areas (repulsion effect) and complicates the final treatment. Our approach: targeted bait in gel or in stations, residual treatment only where necessary, and zero product on food preparation or coating surfaces.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Residential treatment 1 bedroom + 1 kitchen
- Full accommodation (2 visits included)
- Restaurant or grocery store (monthly contract)
What influences the quote
- Surface or volume to be treated
- Extent of the infestation or situation
- Accessibility of the areas concerned
- Response time requested (planned or emergency)
- Scope of the desired warranty
- Documentation required for insurer, notary or audit
The inspection is non-binding. We evaluate on site (or by phone as the case may be) and give you a written estimate adapted to your building before any work begins. No unpleasant surprises at the end.
What you can do before our tour
- Do not use any aerosol products in infested areas: this disperses insects and distorts our diagnosis
- Do not move furniture or appliances (technicians want to see them in their normal position)
- Store a dead specimen in a closed plastic bag to confirm the species
- Note where and when you observe insects (useful for targeting treatment)
- For bed bugs specifically : do not throw away the mattress before we come, this complicates the quote and can spread the infestation
Common mistakes to avoid
- Buy consumer products : they kill a few visible adults but are rarely effective over the entire cycle
- Multiplying home treatments : creates resistance in certain populations, complicates our protocols afterwards
- Wait for it to pass : the population doubles every 28 days for most species, the cost of treatment too
- Do not report to neighbours (in condominiums or triplexes): the infestation returns if neighbouring units are not treated
Questions
Why are German cockroaches resistant to commercial insecticides?
This species has developed genetic resistance to several common molecules (pyrethroids, organophosphates) after decades of massive use. Our professional gels use different active ingredients (fipronil, hydramethylnone, indoxacarb) in rotation to avoid this resistance.
My neighbor has German cockroaches, should I be worried?
Yes, especially in condominiums or multiplexes. This species migrates through technical passages (pipes, electrical ducts). Coordinated treatment of adjacent units is often more effective than isolated treatments.
Does the treatment also clean the eggs?
Professional gel kills nymphs that hatch by eating the bait brought back to the nest. A 14-day follow-up visit confirms the elimination of the full cycle.
Should the home be evacuated during treatment?
No. The gel is applied in cracks and areas inaccessible to children and pets. No occupancy restrictions.
How long before the German cockroach is totally eliminated?
Allow 2 to 6 weeks depending on the species’ cycle. A visible reduction appears from the first week. Complete elimination occurs after all the eggs present have hatched and the second wave has been treated.
What exactly does the written warranty cover?
Recurrence of the same species in the treated area during the indicated period (typically 60 to 90 days for the German cockroach). If the infestation returns, we schedule a follow-up according to the conditions of your warranty.

Frequently Asked Questions: German Cockroaches
What distinguishes the German cockroach compared to other cockroaches?
The German cockroach is small (about 1.5 cm), light brown, with two parallel dark stripes behind the head; It is the most common species inside buildings. It reproduces extremely quickly and concentrates in kitchens and bathrooms, near heat and humidity. In Longueuil and Brossard, it is often found in the kitchens of homes and restaurants.
Why does the German cockroach spread so quickly?
A single ootheca can contain dozens of eggs and the female carries it until hatching, which protects the new generation; The reproductive cycle is very short. They slip into cracks, appliances and hot motors, easily dispersing throughout a building. This rapid proliferation makes professional treatment almost indispensable.
Is German cockroach a health risk?
Yes, by circulating between waste and food surfaces, it can carry bacteria and contaminate food. Its feces, moults and secretions are also recognized allergens that can aggravate asthma, especially in children. An infestation in the kitchen must therefore be taken seriously.
How is a German cockroach treatment performed?
Our technician inspects the hotbeds (kitchen, bathroom, appliances) and applies an approved gel bait combined with targeted treatments in the cracks. Because the eggs are protected in the ootheca, follow-up is usually required to treat new generations. We give you preparation instructions to optimize efficiency.
How much does a German cockroach treatment cost?
The price is based on an assessment, depending on the extent of the situation and the number of follow-up visits required. In a building, the infestation can affect several units, which influences the price and requires an inspection. The amount is communicated to you before the work, our services being paid.
Can a German cockroach infestation be completely eliminated?
We aim for sustainable results evaluated on a case-by-case basis, with follow-up to treat generations from eggs after the first visit. In collective housing, success also depends on the treatment of neighbouring units and the collaboration of the occupants in the preparation. Our technician explains realistic measures for long-term control rather than an absolute promise.
