Fly Control Frequently Asked Questions & Safety
Factual answers to common resident and commercial owner concerns regarding drain fly recurrence, restaurant compliance, zapper hazards, and biological drain foaming.
Why do drain flies keep returning to my bathroom floor trap in Bangalore?
Drain flies breed inside the thick, gelatinous biofilm (organic slime made of soap scum, hair, and dead skin) coating the inside walls of your plumbing pipes and floor traps. Pouring hot water or bleach only runs through the center without dissolving this heavy slime layer. Until the organic biofilm is digested using specialized bio-enzymatic foam, larvae will continue to hatch continuously every 8 to 14 days.
Do house flies bite humans in Bangalore?
Common house flies (Musca domestica) do not possess biting or piercing mouthparts; they have sponging mouthparts. If you experience sharp, painful day bites outdoors or near livestock, the insect is likely a stable fly (Stomoxys calcitrans) or a horse fly. However, house flies pose a far greater medical hazard through mechanical pathogen contamination of food and dining surfaces.
Are fruit flies coming from inside the fruit, or from outside?
Fruit flies do not originate from inside clean fruit. Adult female fruit flies lay microscopic eggs on the outer peel of overripe or damaged fruits, tomatoes, and bananas while still in wholesale markets or grocery displays. When brought indoors into warm kitchens, eggs hatch in 24 to 30 hours, giving the false illusion that the flies emerged from within the fruit.
How dangerous are flies to restaurants and commercial cloud kitchens?
Flies are classified as critical sanitation vectors under FSSAI food safety regulations in India. A single house fly carries over 65 documented human pathogens, including Salmonella, E. coli, and Cholera. Health inspectors can issue hygiene penalty notices or temporary closure orders if active fly infestations or non-compliant zapper units are detected in food preparation or dining areas.
Why are high-voltage electric zappers prohibited in commercial dining spaces?
When an electrocutor grid zaps a fly, the electrical arc creates an explosion that atomizes the insect, scattering airborne body fragments, digestive enzymes, and viable bacteria up to 2 meters. In contrast, modern HACCP-compliant fly management relies on silent UV-A light traps paired with pheromone glue boards that trap flies intact.
How long does a professional fly control treatment last?
Our bio-enzymatic drain foaming digests existing pipe biofilm, preventing new adult emergence for 4 to 8 weeks depending on bathroom water volume and usage. Exterior perimeter residual sprays maintain an active barrier for approximately 30 to 45 days. Combining treatments with proper waste management and window screening provides year-round protection.
Are the bio-enzymatic drain cleaners safe for septic tanks and plumbing?
Yes, 100%. Our bio-enzymatic formulations contain naturally occurring, non-pathogenic bacterial cultures and enzymes. Unlike harsh chemical drain openers containing caustic soda or sulfuric acid that can corrode PVC pipes and damage septic tank bacterial balances, our bio-enzymatic treatments actually enhance septic tank digestion.
What is the pricing for fly control services at SLV Pest Control?
Pricing is based on property type (apartment bathroom bio-foaming, villa package, or commercial restaurant/cloud kitchen) and the number of floor traps and UV light trap units required. We provide transparent quotes following an on-site inspection.
