Key points
- Identifying the species matters: German, American and brown-banded cockroaches hide in different places and need different treatment points.
- Gel bait is placed in small spots in cracks, hinges and voids; cockroaches feed on it and carry its effect back to their hiding places.
- Rotating bait types helps when cockroaches stop eating a particular bait.
- Gel does not destroy eggs inside egg cases, so a follow-up visit is needed to deal with newly hatched nymphs.
- Household sprays near bait spots can repel cockroaches and reduce how well the treatment works.
Good cockroach control is less about spraying a room and more about three things: finding where cockroaches live, getting the right bait to them, and removing whatever keeps them coming back. This page explains how our cockroach treatment works. It covers the species we look for, the inspection, gel baiting and bait rotation, crack-and-crevice work in kitchens and drains, what you can do to help, and why the follow-up visit matters.
It follows our Integrated Pest Management (IPM) approach: inspect first, advise on sanitation and proofing, then treat only where treatment is needed.
Which cockroaches are we dealing with?
Different species hide in different places and respond differently to treatment, so identification comes first. Three species are regularly found in Indian homes and businesses.
| Species | How to recognise it | Where it usually hides | What it means for treatment |
|---|---|---|---|
| German cockroach | Small and light brown, with two dark stripes just behind the head | Kitchens, cabinet hinges, behind fridges and stoves, inside appliances | Breeds quickly indoors, so it needs thorough gel baiting and a follow-up visit |
| American cockroach | Large and reddish-brown, and can fly short distances | Drains, gully traps, sewer lines, ducts, store rooms and basements | Needs drain and outdoor treatment plus proofing, not just kitchen baiting |
| Brown-banded cockroach | Small, with pale bands across the body | Drier, warmer spots such as furniture, electronics, upper cupboards and ceilings | Bait has to go beyond the kitchen, into rooms and furniture |
Small, wingless cockroaches running about in daylight are usually nymphs (young cockroaches). Seeing them often means breeding is happening inside the premises, not just occasional visitors coming in.
Warm, humid conditions keep cockroaches active through much of the year. That includes Goa's humid coastal climate and heavy monsoon, and Hyderabad's hot summer and rainy season. Our article on what to expect from seasonal pests explains how activity shifts through the year.
What happens during a cockroach inspection?
Before any treatment, the technician works out where the cockroaches are living and why they are thriving there. It helps a great deal if you can say when and where you have seen them.
- Hiding places: under the sink, cabinet hinges and corners, behind and under the fridge, stove and dishwasher, and gaps around pipes, tiles and skirting.
- Wet areas: bathroom floor traps, kitchen drains, gully traps and drain chambers.
- Storage: store rooms, cardboard boxes, stacked crates and false ceilings in commercial premises.
- Signs of activity: pepper-like droppings, brown egg cases, shed skins, smear marks and a musty odour.
- Conditions that help cockroaches: leaks, grease build-up, food residue, open bins and clutter.
The inspection decides where bait goes and whether drains need separate treatment. It also shapes the sanitation and proofing advice you receive.
How does cockroach gel baiting work?
Cockroach gel bait is a food-based bait containing an insecticide. It is applied in small spots exactly where cockroaches travel and shelter. Cockroaches feed on it and return to their hiding places, where many of them die.
Cockroaches also feed on droppings and dead cockroaches. Because of this, some baits keep working on insects hiding in places no treatment can reach directly.
Gel suits occupied kitchens and homes well. It is placed in cracks, hinges and voids, out of reach and largely out of sight. It also causes far less disruption than spraying open surfaces. Typical placement points include:
- cabinet hinges and inside corners of cupboards
- pipe entries under sinks and wash basins
- the backs and undersides of appliances
- gaps in tiles, skirting and countertop edges
- cracks near drains and in service areas
Why do we rotate baits?
Some cockroach populations stop eating a particular bait, a problem known as bait aversion. Repeated use of one insecticide group can also make a population less susceptible to it over time.
At follow-up visits the technician checks how much bait has been eaten. If uptake has dropped, they switch to a bait with a different formulation or active-ingredient group. On ongoing contracts, rotation is planned in advance rather than left until the bait stops working.
Why you should not spray near the bait
Household aerosol sprays and strong cleaners can contaminate bait spots or repel cockroaches away from them. That undoes the treatment. Please avoid spraying or wiping the bait points, and ask the technician which surfaces are safe to clean.
What is crack-and-crevice treatment, and when is it used?
Crack-and-crevice treatment means applying a product directly into narrow gaps, voids and hiding places rather than across open surfaces. We use it alongside gel where hiding places are extensive, where drains and service ducts are involved, or where an infestation is heavy. Busy commercial kitchens may also need a more intensive kitchen treatment.
Products are chosen to suit the site and applied according to label directions. We do not publish product names or doses here, because the right choice depends on what the inspection finds.
Treating drains and wet areas
American cockroaches in particular travel through drains and enter through floor traps and broken covers. Drain work can include treating floor traps, gully traps and drain chambers. You will also get practical proofing advice:
- pour water into rarely used floor traps so the water seal stays filled
- fit mesh covers or grates on open drains
- repair or replace broken drain-chamber covers
- seal gaps around pipes and cables where they pass through walls
Why does sanitation matter as much as treatment?
Cockroach control works best as a partnership. Gel bait competes with every crumb, grease spot and uncovered bin nearby. The less food and water cockroaches can find, the more readily they take the bait.
- Clean grease from around the stove and behind appliances regularly.
- Store food, including pet food, in sealed containers, and do not leave it out overnight.
- Wash dishes before bed rather than leaving them in the sink.
- Use lidded bins and empty them daily.
- Fix dripping taps and leaking pipes.
- Cut down on cardboard and clutter, which cockroaches use for shelter and egg-laying.
Food businesses need the same habits built into cleaning schedules, back-of-house routines and checks on incoming deliveries. Our restaurant pest management and hotel pest management pages explain how cockroach control fits into a wider programme for kitchens, stores and staff areas.
How should you prepare for treatment?
Preparation for gel baiting alone is usually light. It is more involved where crack-and-crevice or drain treatment is planned. Our step-by-step guide on how to prepare for cockroach gel treatment covers it in detail.
In short, give the technician access to cabinets, appliances and drains, and put away or cover exposed food. Arrange for children and pets to be kept away from treated areas as advised. A responsible adult or staff member should be present during the visit to show the technician around.
Is cockroach treatment safe for children and pets?
Gel is applied in small amounts in places children and pets cannot easily reach, which keeps exposure low. Safety still depends on the right product, the right placement and your cooperation afterwards.
- Keep children and pets away from treated areas until they are dry, or for as long as the technician advises.
- Do not touch, scrape off or move bait spots.
- Ventilate rooms after any spray application.
- Wash hands after handling items from treated cupboards.
- If anyone feels unwell, or a pet may have eaten bait, see a doctor or vet promptly.
We maintain Material Safety Data Sheets for the products we use. Our Goa operation is a licensed pest control operator (Directorate of Agriculture, Goa) and uses CIB&RC-registered products.
What happens at the follow-up visit?
Gel bait does not destroy eggs sealed inside egg cases, so new nymphs can hatch after the first visit. A follow-up visit is therefore planned a few weeks later. At that visit the technician:
- checks how much bait has been eaten at each point
- tops up bait and rotates it if uptake has dropped
- treats spots that were missed or have become active
- reviews sanitation and proofing with you
You may see cockroaches out in the open during the first few days as the bait takes effect. This usually settles down.
Shared walls, common drains and busy kitchens can bring repeated cockroach pressure. In those cases, scheduled visits under an annual maintenance contract are often more practical than one-off treatments.
In Goa, clients receive service reports after visits along with WhatsApp updates. Food businesses there receive documentation aligned with HACCP and FSSAI audit expectations. Where a warranty applies, it covers the treated area as set out in the service agreement. Cockroaches coming in from neighbouring premises need prevention on your side as well. The details are in our terms and conditions.

Frequently asked questions
QHow long does cockroach gel bait take to work?
Most people notice fewer cockroaches within the first several days, as insects feed on the bait and die in their hiding places. Full control takes longer, because eggs already laid will still hatch. That is why a follow-up visit is planned a few weeks after the first treatment. How quickly things improve also depends on the species, how established the infestation is, and how well food and water sources are controlled.
QDo we need to leave the house during cockroach treatment?
For gel baiting alone, households usually do not need to leave. The bait is placed in small spots inside cracks, hinges and voids. If crack-and-crevice or drain treatment is also planned, the technician will tell you which rooms to keep clear and for how long. Children and pets should stay away from treated areas until they are dry or as advised.
QWhy am I seeing more cockroaches after the treatment?
In the first few days, cockroaches affected by the bait often leave their hiding places and appear in the open, sometimes during the day. This is usually a sign the bait is being eaten, not that the treatment has failed. If sightings stay high after a couple of weeks, let the technician know. They can check bait uptake and adjust placement or switch baits at the follow-up.
QCan I use my own cockroach spray between visits?
It is best not to. Household aerosols and strong cleaners can contaminate bait spots or drive cockroaches away from them, which slows the treatment down. If you see cockroaches between visits, note where and when, and share this with the technician. Swatting or vacuuming a stray cockroach is fine, but avoid spraying or wiping near the bait points.
QHow many visits will a cockroach treatment need?
Most treatments involve an initial visit and at least one follow-up, so newly hatched nymphs can be dealt with. Heavy infestations, large kitchens or buildings with shared drains may need more. Restaurants, hotels and other food businesses usually benefit from scheduled visits throughout the year, often under an annual maintenance contract, because cockroaches can be brought in with deliveries or travel from neighbouring premises.
QWill treatment stop cockroaches coming from my neighbour's flat?
Treatment covers your own premises. In apartment buildings, cockroaches can move through shared drains, ducts and gaps around pipes. Sealing those gaps, keeping floor traps filled with water and fitting drain covers all reduce movement between flats. Where several flats are affected, a coordinated treatment through the housing society generally gives better results than individual flats treating at different times.
QIs gel bait safe to use in a kitchen where we cook?
Gel bait is placed in cracks, hinges and voids rather than on worktops or cooking surfaces, which keeps it away from food contact. Store food in sealed containers, do not move or wipe the bait spots, and wash hands after handling items from treated cupboards. If you are unsure about cleaning a particular surface, ask the technician before you clean it.
