Cockroaches in the kitchen, termites eating a door frame, rats in the loft - pest problems are common in Coimbatore homes, shops and offices, and they are easy to make worse with the wrong treatment. This guide explains the kinds of treatment available, how to pick a careful, licensed operator, and how to keep your family safe while the work is done.
Different pests need different chemicals, methods and follow-up. Before you call, try to note what you have seen:
Take a few photos. A good operator will ask to inspect before giving a price for anything more than a routine cockroach treatment.
Termite damage is the costliest pest problem for Kovai homes, because it is hidden inside wooden frames, cupboards and furniture until the wood gives way.
There are two situations:
Ask for the name of the chemical, the areas to be drilled, and a written warranty period. A treatment that only sprays the visible mud tubes will not last.
1. Licence. Businesses that use insecticides for pest control need a licence under the Insecticides Act, issued through the state agriculture department. Ask to see it. A licensed operator is also more likely to use registered products at the right dose.
2. Inspection first. For termites, rodents and bed bugs, an operator who quotes a fixed price over the phone without seeing the property is guessing.
3. Clear chemical information. Ask which product will be used, why, and what the label says about re-entry time. Refuse unlabelled chemicals in plain bottles.
4. Written quote and warranty. The quote should list the pests covered, the area in square feet, the number of visits, and what happens if the problem returns.
5. Trained staff. Ask whether the people who will come to your home are trained, and whether they use gloves and masks. Careless handling is a warning sign.
6. References. Ask neighbours, your apartment association or your office manager who they use, and whether the problem came back.
Pest control chemicals are designed to kill living things, so treat them with respect:
If someone feels unwell after a treatment, get medical help and keep the product name with you.
Chemicals work best when the house does not keep inviting pests back:
Restaurants, food shops, hostels and warehouses usually need a regular service contract rather than one-off visits. Ask for a monthly or quarterly schedule, a service record you can show during inspections, and a named person you can call between visits. For shared buildings, coordinate with the association: treating one flat while the neighbouring flats stay untreated often just moves the cockroaches next door.
If you already use a housekeeping agency, ask whether they coordinate with your pest control operator; our guide to hiring housekeeping services covers what to check with them.
Note which pests you have seen and where, take photos, and call two licensed operators for an inspection. Compare the written quotes line by line - chemical, area, visits and warranty - rather than on price alone. You can also find pest control services listed in the Kovai Yellow Pages directory.
Operators who use insecticides commercially need a licence under the Insecticides Act, issued through the state agriculture department. Ask to see the licence, the name of the chemical they will use and its label, and get the details on the bill.
It depends on the chemical and how it is used. Ask the operator which product they will use, how long the family and pets should stay out of the treated rooms, and what to cover or remove before they start. Follow the product label, and if anyone at home has asthma or allergies, ask a doctor first.
It depends on the method and the chemical. Post-construction termite treatment usually comes with a service period of a few years, stated in writing. Ask what the warranty covers, how long it lasts and whether follow-up inspections are free.
Gel baits, traps and household sprays can handle small cockroach or ant problems. Termites, bed bugs and large rodent problems usually need a trained operator, because the chemicals, drilling and dosage are harder to get right.
