200-Seat Fine-Dining.87% Fewer Complaints.
A premium fine-dining restaurant in Connaught Place, New Delhi was losing customer reviews to housefly complaints during the summer monsoon transition. Chronovex deployed a discreet, food-safe pest control programme — 4× UV electric grid killers and 2× dining-hall glue traps in coordinated zones. 30 days later: 87% drop in complaints, +0.6★ review uplift.
When 1-star reviews start mentioning flies
Premium F&B operators in Delhi monsoon season face a paradox: customers expect open dining ambience, but flying insects from CP's street vendors and rain-soaked drains threaten food safety perception.
12 fly-related complaints in 28 days, 2 dropped to 1-star
The restaurant's general manager, Vikram, walked us through 12 fly-mention reviews on Zomato, Swiggy and Google in a single month. 2 had dropped to 1-star — a direct revenue threat to a CP fine-dining brand. Zomato's algorithm was downranking the listing on hygiene signals.
Flies enter through the kitchen pass, not the dining hall
Most pest-control sales reps had pitched ceiling-mounted UV killers in the dining hall. Our F&B specialist, Karan Mehta (FSSAI certified pest control auditor), ran a fly-tracking exercise over 3 dinner services. 73% of fly intrusion happened through the kitchen pass during plate hand-offs — not from the entrance.
4 UV electric grid killers (kitchen-zone) + 2 glue traps (dining-edge), discreet placement
We deployed 4 industrial UV electric grid killers above the kitchen pass and along the back-of-house corridor — zones where customers can't see them but flies congregate. 2 silent glue traps on dining hall perimeter walls, painted to match décor. All placement complied with FSSAI Schedule 4 distance rules.
30 days later: 87% complaint drop, +0.6★ review uplift
The internal hygiene logbook recorded 12 fly complaints in the 28 days before install. In the 30 days after: 2 complaints (both kitchen-side, not dining). Zomato 30-day rolling rating moved from 4.1 to 4.7. Vikram signed our quarterly service contract on day 33.
Exactly what was installed
Full bill-of-materials with HSN codes, GST-billed and warranty-tracked.
I'd already bought 2 fly killers from another supplier and they didn't move the needle. Karan asked to watch a dinner service before quoting — that's when I knew we'd called the right team.
