Cockroach treatment

Cockroaches (German, Oriental or American) are the hardest pests to eradicate without professional products. They live in colonies, lay eggs fast and resist consumer insecticides. In buildings, they circulate between flats through service shafts and communal areas.

Cockroaches (German, Oriental or American) are the hardest pests to eradicate without professional products. They live in colonies, lay eggs fast and resist consumer insecticides. In buildings, they circulate between flats through service shafts and communal areas.

Our treatment relies on domino-effect insect gel: cockroaches carry the gel back to the nest, and the entire colony is wiped out over a few weeks, including eggs and hidden individuals.

How to spot the problem

The signs to identify

Live cockroaches at night

Cockroaches are nocturnal. If you see them in daytime, the population is already significant.

Black droppings

Small black grains (1–2 mm) in cupboards, behind the sink, on skirting boards, behind appliances.

Rancid smell

Characteristic sweet-rancid odour in kitchens and bathrooms when the infestation is established.

Oothecae (egg capsules)

Small brown capsules, 5–8 mm, containing 20–40 eggs. Glued into corners, under furniture, behind skirting boards.

Why act fast

The risks of leaving an infestation untreated

Food contamination

Cockroaches carry salmonella, E. coli, parasites. They contaminate cooking surfaces and stocks.

Allergies and asthma

Droppings and moults are a recognised cause of allergic asthma, particularly in children.

Image (business)

For restaurants, hotels, food shops: one cockroach spotted by a customer can wreck a reputation. FAVV (food safety) sanctions are heavy.

Methodology

Professional colony-effect insect gel

Supermarket sprays kill a few individuals and scatter the colony. Our gel works the opposite way: roaches carry it back to the nest, and the domino effect collapses the colony in 2 to 3 weeks.

  1. 1

    Thorough inspection

    Kitchen, bathroom, service shafts, communal areas. Species identification and concentration hotspots.

  2. 2

    Gel application

    Discreet placement of micro-droplets of baited gel at strategic points. No spraying, cupboards stay in place.

  3. 3

    Communal areas (buildings)

    In buildings, cockroaches migrate via shafts. We simultaneously treat neighbouring flats and communal areas, coordinating with the manager if needed.

  4. 4

    3-week check

    Follow-up visit, targeted re-application if needed. Written result guarantee 3 to 6 months.

« Cockroaches in the kitchen of an old building. Gel treatment, nothing for 6 months. The team also treated the communal areas at no extra cost — very honest. »

Frequently asked questions

Do I have to empty the cupboards?
No. We treat discreetly without moving dishes or stocks. It's a major advantage of gel over spray.
Can I cook normally after the intervention?
Yes, immediately. Gel is placed outside food-contact zones. No safety waiting period.
My neighbour has cockroaches — what should I do?
In a building, treating one flat alone isn't enough. We contact the managing agent to coordinate a global treatment — more effective and often cheaper per occupant.
