The most common indoor pest in Qatar, and the one most likely to return if only the surface is treated.
Nocturnal and thigmotactic — they prefer tight, warm, humid gaps where their bodies touch a surface above and below. That means cabinet joints, appliance motors, drain lines and service risers, not open floors. Seeing one in daylight usually means the harbourage is already crowded.
Cockroaches move between drains, waste and food preparation surfaces, and can carry bacteria on their bodies. Their shed skins and droppings are also a recognised trigger for asthma and allergies, particularly in children.
Gel bait placed directly in harbourage points, so foraging insects carry the active ingredient back to the nest, combined with residual treatment of cracks and entry routes. A follow-up visit timed to the breeding cycle deals with nymphs that hatched after the first treatment.
Practical steps that make a repeat infestation far less likely after treatment.
Fit drain covers and keep sink and floor traps filled — dry traps are an open door from the sewer
Store dry goods in sealed containers and clear crumbs from under appliances, not just the worktop
Seal the gaps around pipework under sinks and behind kitchen units
Take waste out nightly and rinse bins; a damp bin liner feeds a colony on its own
The things people ask us most before booking this treatment.
You should see activity drop within a few days of the first treatment, but the infestation isn't finished until the eggs that were already laid have hatched and been dealt with. That's why we schedule a follow-up timed to the breeding cycle — treating once and stopping is the most common reason cockroaches come back.
Cockroaches are nocturnal and stay hidden while there's room in the harbourage. Seeing one in daylight usually means the hiding place is already crowded, so the few you see are a small fraction of what's behind the units.
Usually not. In buildings with shared drains and service risers they move between units, so an untreated flat next door will reseed yours. We'll tell you honestly when that's what we're seeing, and it's worth raising with building management rather than paying to treat the same problem repeatedly.
