Everything in this section is written for the pests that actually turn up in Lebanese kitchens, roofs, balconies and shops, and for the conditions that drive them here. Advice written for another country will tell you to treat for pests we do not have, at times of year that do not match our season, with products our local populations no longer respond to. What you read here starts from what is documented in Lebanon and from what our technicians deal with in Beirut, Metn, Baabda and Keserwan.
The local calendar matters more than most pest advice admits. The tiger mosquito, Aedes albopictus, is established along the humid western slope up to roughly a thousand metres of altitude and stays active from late April into December, with one peak in July and a second in late September and early October, while the dry inland including the Bekaa sees very little of it. Rodent and fly pressure works differently, following the rubbish collection calendar rather than the weather, so a suspension in Beirut or Metn brings complaints within days no matter which month it happens in.
A fair amount of what circulates online is simply wrong for Lebanon. House mice sampled here for a 2022 study in Scientific Reports carried Vkorc1 resistance-linked mutations in 58.3% of cases, which is why the anticoagulant blocks sold in supermarkets so often sit untouched in the corner of a kitchen with nothing to show for weeks of waiting. Drywood termites are the species documented in Lebanon, including specimens collected in Beirut, so a termite problem here usually lives in roof beams, old shutters and furniture rather than under the floor. We write these things down because the alternative is a treatment aimed at the wrong target.
You will also find plain explanations of how this work is supposed to be done. Household pest control in Lebanon is licensed by the Ministry of Public Health through its Sanitary Engineering Service, under the technical conditions of Decree 5100 of 1982, and agricultural pesticide licensing sits on an entirely separate track under the Ministry of Agriculture. There is no public register you can search, so the only way to check a company is to ask to see the certificate and read which ministry issued it. The Ministry has also banned aluminium and zinc phosphide for pest control in residential and populated areas, and neither belongs in a home.
Most of what people ask before booking comes down to the same short list of concerns: whether a treatment is safe around children and pets, how long the visit takes, whether the family needs to leave the flat and for how long, what to move or cover before the technician arrives, why certain jobs need a second visit, and which areas we cover. The service page for each pest answers those questions for that particular treatment, and anything still left over you can put to us directly on +961 3 265900 or at hello@grmcpestcontrol.com.
