Condo Mosquito Spraying: When Tenants Started Moving Out Because of Mosquitoes

When "Mosquitoes" Became the #1 Reason on Move-Out Forms

Akkaradet, 39, juristic manager of an 8-storey, 320-unit condo in Lat Phrao, Bangkok, noticed the move-out notices piling up — with one phrase repeating: "too many mosquitoes, can't live here."

The last straw: two Building-B tenants caught dengue in the same month. One posted a review in a room-hunting group with photos of bite-covered legs. The condo's rating fell to 2 stars, vacancies climbed to 14 units — roughly 140,000 baht in lost rent every month.

The Breeding Sites Nobody Owned

• The B2 car-park sump pit: still water, dark and undisturbed all year — a mosquito factory.
• Leaf-clogged perimeter drains holding pockets of stagnant water.
• The old fire-equipment room with rain-leak buckets.
• The lobby vertical garden — every pot saucer full of water.

Housekeepers sprayed aerosol cans nightly and six electric traps ran around the clock, but new mosquitoes hatched every seven days as long as the breeding sites remained.

The Fix: ULV Spraying That Reaches Every Level of the Building

The board approved the mosquito spraying service of World Health Disinfection (WHD). The team fogged sub-20-micron ULV with WHO-standard Deltamethrin 2.5% through both basement levels, perimeter drains, refuse rooms and common gardens — starting at 5 a.m. before residents needed the car park — and reported every standing-water point for permanent fixes.

10 Reasons Condos & Apartments Choose WHD

1. ULV mist penetrates sumps, pipes and basement dead zones aerosols never reach.
2. WHO-standard solution, resident- and pet-safe once dry.
3. Early-morning scheduling that never disturbs residents.
4. No stains on cars or surfaces, no lingering smell indoors.
5. Free whole-building survey with an engineer-ready report.
6. Documents for resident notices and annual general meetings.
7. Monthly schedule keeps mosquitoes suppressed all rainy season.
8. Professional, uniformed crew residents trust on sight.
9. Pricing that fits juristic budgets — free quotation.
10. Measurable results from week one.

Before / After

Before: Monthly move-outs, 2 dengue cases, 2-star reviews, 14 vacant units, 140,000 baht/month lost.

After: Three monthly treatments later — car park and lobby virtually mosquito-free, zero new cases, reviews back to 4 stars, vacancies down to 3 units, and an annual care contract approved.

"I used to see spraying as an expense. Against 140,000 baht of lost rent a month, it's the cheapest investment this building ever made." — Akkaradet, Juristic Manager

Do cars need to be moved? No — ULV mist leaves no residue on vehicles and the crew avoids direct spraying onto cars.

How often should a building spray? Monthly in the rainy season, every 2–3 months otherwise, alongside permanent water-point fixes.
