Flying Insect Control (Flies, Wasps, etc.)

Houseflies and bluebottles — source first, then treatment

Where they breed

Bins, food waste, animal waste, and decaying matter around external areas. Indoors, dirty drip trays and uncleaned spills attract them.

Control measures

• Hygiene: sealed, lidded bins; frequent waste removal; clean food areas
• Proofing: screens on serving hatches and windows where suitable; door discipline
• Treatments: targeted residuals on resting surfaces; UV fly units in commercial food areas (sited away from prep surfaces and in line with HACCP)

Fruit flies (Drosophila) — small flies, big signals

Causes

Fermenting residues in bottle bins, drains, mop buckets, and soda lines. In bars and cafés, build-up under equipment and in floor joints sustains them.

Control measures

• Deep clean wet wells, drip trays, under-counter voids and floor joints
• Treat with drain cleaners formulated to remove biofilm (not bleach alone)
• Use targeted, food-safe residuals around external breeding points as needed
• Implement nightly closures: dry mats, empty mop buckets, cap bottles

Drain flies (Psychodidae) — fix the biofilm

Causes

Organic slime in traps, gullies and slow drains. Adults rest on walls near sinks and toilets; larvae live in the biofilm.

Control measures

• Mechanically clean and treat traps and gullies; apply enzyme/biofilm treatments
• Repair slow drains; replace cracked or leaky traps
• Apply light residuals to resting surfaces if adult numbers are high

Cluster flies — seasonal loft invaders

Behaviour

In autumn, cluster flies seek lofts and window frames to overwinter, then re-emerge on warm spring days.

Control measures

• Loft treatments with appropriate space sprays when voids are accessible and safe
• Sealing of obvious gaps and screening of louvres where practicable
• Vacuum removal in living spaces; avoid smearing carcasses on walls

Wasps — protect entrances and indoor spaces

Risks and response

Nests near doors, play areas or inside wall cavities risk stings and disruption. DIY often aggravates colonies.

Control measures

• Professional nest treatment (concealed or exposed) with safe access at height
• Advice on when to seal entry to prevent wasps emerging indoors
• Post-treatment prevention: fix soffit gaps, fit vent grilles, manage sweet residues and bins

Mosquitoes and midges — water management

Causes

Standing water in water butts, trays, blocked gutters and garden features.

Control measures

• Eliminate standing water; fit lids and meshes to water butts
• Maintain gutters; treat features with appropriate larvicides where needed
• Add screens to bedrooms if practical during peak season

Commercial flying insect control — compliance and uptime

Food premises, healthcare and education require reliable control with documentation. We site and service UV fly units, specify screen grades, and document treatments and hygiene recommendations. Trend analysis helps target recurring sources.

Residential flying insect control — quick fixes that last

For homes, we combine targeted treatments with simple changes: bin discipline, drain cleaning, mending screens, and seasonal loft checks. When wasps are involved, we prioritise safety and rapid response.

Prevention checklist you can start today

• Keep bins lidded and clean; rinse recycling
• Dry mats and mop buckets each night; clean drip trays
• Fit or repair simple fly screens where suitable
• Maintain drains and traps; deal with slow drainage
• Seal obvious gaps at soffits and around loft vents
• In summer, cover sweet drinks outdoors; manage fallen fruit
