Common Pests in Lebanese Homes — And How to Handle Them

Lebanon's mild winters and warm coastal summers create year-round pressure from a familiar cast of pests. A bit of seasonal calendar awareness combined with sensible building practices solves 80% of the problem.

Common offenders by season

• Spring — ants and mosquitoes. Pavement ants invade kitchens chasing sweets; tiger mosquito (Aedes albopictus) hatches in any standing water.
• Summer — German cockroaches. Apartment-dwelling, spread through plumbing risers; one neighbour's untreated infestation becomes the whole stack's problem.
• Autumn — rats and mice. Move indoors as gardens cool down; check the underside of doors and the kitchen plumbing penetrations.
• Winter — bedbugs (year-round, peak in heated rooms). Travel-borne; check seams of mattresses and luggage zips after trips.

Sensible building practice first

1. Seal under-door gaps with brush strips (rats can squeeze through 12 mm).
2. Caulk all plumbing penetrations to the apartment.
3. Cover kitchen and bathroom drains; pour a kettle of hot water with a splash of vinegar weekly.
4. Empty plant saucers, gutter blockages, and rooftop tank overflow trays to deny mosquitoes breeding sites.
5. Vacuum upholstery weekly and dispose of the bag outside immediately.

When to call a licensed exterminator

• Visible cockroach activity by day (means a major hidden population).
• Rodent droppings or gnawed wiring.
• Bedbug bites in clusters of three on exposed skin.
• Whole-building treatments — much more effective than per-apartment.

Confirm the firm uses Ministry of Agriculture–registered products, provides the safety data sheet, specifies a re-entry interval, and offers a follow-up visit at 14–21 days included in the price (essential for the second roach generation).
