A fly loose in a Beirut kitchen has already done its growing somewhere else, in wet organic material a few metres away, so swatting buys you the evening and little more.
Finding that material is the real work, so a GRMC visit begins at the drains, the bin store and the back door.
Small flies and house flies are two different problems
Small flies that breed indoors
Drain flies, the fuzzy ones that hop across a tile near a gully, breed in the film inside floor drains and grease traps, so a spray clears the adults while the pipe releases another batch within days.
House flies and blow flies from outside
The larger flies arrive from the bin area, the delivery door and the roof. A cluster of metallic blow flies in one room means a dead animal in a wall or ceiling void, where rodent control takes over.
How pest control licensing works in Lebanon
Pest control in homes and businesses is licensed by the Ministry of Public Health, through the Directorate of Health Prevention and its Sanitary Engineering Service, under conditions set by Decree 5100 of 12 April 1982. Agricultural pesticide work sits on a separate track under the Ministry of Agriculture, and the two licences are not interchangeable.
Lebanon keeps no public register of pest control companies, so a customer can only ask which ministry issued the licence and see the certificate. The Ministry of Public Health has banned aluminium and zinc phosphide for pest control in residential and populated areas nationwide.
Fly pressure in Beirut follows the collection calendar
Indoors, fly numbers track how long the rubbish has stood downstairs more closely than the season, and collection suspensions keep recurring across Beirut, Metn and Keserwan. The Jdeideh landfill is at capacity, its last expansion cell only buys time to the end of 2026, and the Ramco and CityBlu collection contracts expire in the same window. Long empty and damaged buildings add to it, particularly in Medawar, Mar Mikhael, Gemmayzeh and Karantina.
How a fly treatment is put together
Inspection before anything is applied
We work backwards from where the flies rest to the material they came out of, opening floor drains and checking the bin room, roof drains and balcony gullies.
Clearing what the larvae live in
Drains and grease traps are opened, scrubbed and dosed with a biological product that digests the film the larvae develop in. Bleach strips the visible surface and leaves that layer where it was, so the same gully starts producing within the week.
Treatment, then proofing
Residual product goes where the adults settle between feeds, clear of anything food touches, with baits and traps where a spray would not suit. Proofing follows with screens, door seals and fly units kept away from preparation benches. A follow-up check is part of the work, since eggs already laid hatch after the adults are gone.
Kitchens, restaurants and food shops
Small flies breeding in the floor drains, the grease trap and the mop store keep a dining room busy however often the front of house is sprayed.
We work across Beirut, Mount Lebanon, Metn, Baabda and Keserwan: Achrafieh, Badaro, Sin el Fil, Jdeideh, Antelias, Jal el Dib, Jounieh, Kaslik and Adma. To arrange a fly inspection, call +961 3 265900 or use the booking page.
