Know your enemy first
Two cockroach species cause almost all the trouble in Indian homes. The German cockroach (small, light brown, sprinter) lives in kitchens, microwaves, drawers and motor housings. The American cockroach (large, reddish-brown, flies short distances) lives in drains, manholes and basements. They need different treatments.
Why cockroaches are more than a nuisance
- They contaminate exposed food with bacteria carried on their legs.
- Cockroach droppings and shed skins are a documented asthma trigger, especially in children.
- They produce a musty odour in heavy infestations — the smell itself is a giveaway.
- They breed shockingly fast; one female can produce 200–300 nymphs a year.
Signs of an active infestation
- Pepper-like droppings inside drawers and behind appliances.
- Egg cases (oothecae) — small, brown, capsule-shaped — stuck in corners.
- A musty, oily smell near the kitchen sink.
- Live roaches visible during the day (a sign the population has outgrown the hiding spaces).
The treatment that actually breaks the colony
Forget the spray-and-pray approach. Modern cockroach control uses gel baiting — a tiny dab of slow-acting bait placed in dozens of strategic points. Workers feed on the gel, return to the harborage, and pass the toxin through the entire colony, including the egg-laying females. Done correctly, a single treatment can collapse a kitchen population within 7–14 days.
For drains and manholes (American cockroach)
These roaches travel up plumbing stacks, so the treatment focuses on the drain network — residual spraying of basements, manhole interiors and floor traps, plus larvicides where standing water exists.
Frequently asked questions
How long does gel-bait treatment take to work?
You should see a major drop in activity within 5–7 days. Full population collapse typically takes 2–3 weeks. Do not spray during this period; you will scare them away from the bait.
Is it safe for kids and pets?
Yes. Modern gels are placed in inaccessible crevices and are formulated to be unattractive to mammals. EntoRid technicians log every gel placement and remove leftovers at the next visit.
How often should I re-treat?
For most homes, once every 3–6 months is enough. Restaurants and busy kitchens may need monthly maintenance.
Why do roaches keep coming back?
Almost always because of one of three reasons: an untreated neighbouring flat, an active drain pathway, or food sources left open at night. A professional inspection identifies which one applies to you.
