Free inspection." canonical: "https://pestswift.com/pests/flies" source: "https://pestswift.com/pests/flies" site: "PestSwift" type: "pest" scientific_name: "Diptera" danger_level: "medium" warranty_days: "60" --- # Flies *Scientific name: Diptera* > House flies, drain flies and fruit flies need source-based treatment — fly traps catch some, but the breeding source (drains, garbage, organic residue) is the real fix. - **Risk level**: Medium risk - **Treatment time**: 1h on-site - **Follow-ups**: 1 follow-up visit - **Warranty**: 60 days - **Active seasons**: Year-round; peak activity April-October ## The flies UAE buildings actually deal with - **House fly** (*Musca domestica*) — 6-7mm, grey, lands on food. Breeds in garbage, animal waste, decomposing organic matter. - **Drain fly / moth fly** (*Psychodidae*) — 2-4mm, fuzzy, hovers near sinks and floor drains. Breeds in the organic film inside drain traps. - **Fruit fly** (*Drosophila melanogaster*) — 2-3mm, red eyes, attracted to overripe fruit and fermented liquid. - **Phorid fly** (*Phoridae*) — small, runs in jerky pattern. Breeds in drain biofilm or decaying organic matter under floor tiles. ## Why the trap on your kitchen window doesn't work A fly trap catches adults that find it. It does nothing to the maggots developing in your kitchen drain biofilm. Within 7-10 days, fresh adults emerge to replace the ones you caught. Real fly control is **source-based**: 1. **Inspection** — locate the breeding source (almost always one specific drain, bin liner gap, or organic-residue area) 2. **Drain treatment** — bio-enzymatic foam that breaks down the organic biofilm where larvae develop 3. **Sanitation review** — bin handling, pet waste, food residue, condensate trays 4. **Adult knockdown** — targeted pyrethrin to clear the existing adult population 5. **UV light traps** for ongoing kitchen / restaurant monitoring ## Restaurants and food businesses Drain fly infestations are the #1 hygiene-inspection failure cause we see in Dubai restaurants. We offer monthly enzymatic drain maintenance plans — see *Restaurant Pest Control*. ## How to identify - House fly: 6-7mm, grey thorax with black stripes - Drain fly: 2-4mm, fuzzy moth-like wings, dark grey - Fruit fly: 2-3mm, tan body with red eyes - Phorid fly: 1-2mm, hump-backed, runs before flying ## Signs of infestation - Hovering swarm around a sink, drain or bin - Tiny dark flies on bathroom mirrors - Larvae (maggots) in floor drains, bins, or under appliances - Pupal cases (small brown 'rice grains') near breeding sources ## Where they hide - Kitchen and bathroom floor drains - Garbage chute openings, bin storage rooms - Behind dishwasher and washing machine drainage - Water-damaged grout and tile (phorid flies) - Restaurant grease traps ## Health risks - Mechanical transmission of Salmonella, E. coli, Shigella - Food contamination - Drain flies can trigger bronchial asthma in sensitive individuals ## Prevention tips - Run hot water down rarely-used drains weekly - Empty kitchen bins nightly and rinse before liner change - Don't leave fruit on the counter (especially banana, mango) - Inspect dishwasher gasket seal monthly ## Our treatment methods - Bio-enzymatic drain foam (drain flies) - Targeted pyrethrin knockdown (adults) - UV light traps (monitoring) - Sanitation consultation - Bait stations for outdoor house fly populations ## Lifecycle in UAE conditions - House fly females lay 100-150 eggs per batch on decomposing organic matter; up to 5-6 batches per lifetime. - Egg-to-adult is 7-10 days at UAE summer temperatures — exceptionally fast. - Drain fly females lay 30-100 eggs in the organic film inside drain traps; eggs hatch in 32-48 hours. - Drain fly larvae feed on the biofilm itself for 10-15 days before pupating in the drain; adults emerge into your kitchen. - Fruit flies have the fastest cycle of all — 8-10 days egg-to-adult on overripe fruit or fermenting liquid. ## Before we arrive - Tape clear plastic over each suspected drain overnight — flies emerging will be trapped against it, identifying the source drain - Don't pour bleach down the drains right before our visit — it disrupts our drain inspection - Empty the bin and rinse the kitchen pedal-bin cavity - Move any overripe fruit out of the kitchen for 24 hours - Note if activity is concentrated by a specific drain, sink or window ## After treatment - Run hot water down rarely-used drains weekly to prevent biofilm rebuild - Don't pour bleach into drains — bleach kills adults but doesn't break down the biofilm where larvae develop - Empty kitchen bins nightly and rinse before liner change - Inspect dishwasher gasket seal monthly — phorid flies often breed in dishwasher residue - Keep fruit refrigerated or covered during fly active months (April-October) ## When DIY isn't enough DIY for flies usually fails because consumer products don't address the breeding source — drain biofilm, specifically. Chemical drain cleaners kill adult larvae temporarily; within 7-10 days new adults emerge from the surviving biofilm. Bio-enzymatic foam digests the actual biofilm matrix and prevents rebuild. For restaurant-grade or commercial fly issues, monthly enzymatic maintenance is the only sustained fix. ## UAE regulatory context Drain fly infestation is the #1 hygiene-inspection failure cause in Dubai restaurants. Dubai Municipality routinely inspects floor drains, grease traps and dishwasher zones; live drain-fly activity during an inspection can trigger immediate corrective-action orders. Commercial food businesses are required to maintain a documented drain-maintenance programme. ## Frequently asked questions ### How do I find which drain is the source? Tape clear plastic over each drain opening overnight. Adults trying to emerge will get trapped against the plastic. The drain with the most flies in the morning is your source. We'll do this on the first visit if it isn't obvious. ### Will pouring bleach down the drain fix it? Temporarily. Bleach kills adults but doesn't remove the organic biofilm where larvae live — flies are back in 7-10 days. Bio-enzymatic foam digests the biofilm and prevents return. ### How do I confirm where flies are breeding? Tape clear plastic over each drain opening overnight. Adults emerging from the drain in the morning will be trapped against the plastic. The drain with the most flies stuck to it is your primary source. We also do this on the first visit if it isn't obvious. ### Will pouring boiling water down the drain fix drain flies? It kills adult larvae temporarily but doesn't dislodge the biofilm. New larvae develop from surviving eggs and biofilm within 7-10 days. Bio-enzymatic foam digests the biofilm matrix itself and prevents recolonisation; that's why professional treatment lasts. ## Related pages - [Mosquitoes](https://pestswift.com/pests/mosquitoes) - [Cockroaches](https://pestswift.com/pests/cockroaches) - [Restaurant Pest Control](https://pestswift.com/services/restaurant-pest-control) - [Hotel Pest Control](https://pestswift.com/services/hotel-pest-control) --- ## About PestSwift **PestSwift** — Dubai Municipality-approved pest control across the UAE.
