You open the kitchen cupboard in the morning and find that something has chewed through a packet of rice. The windows were shut and the kitchen door was closed. Where did the rat get in?

Start under the sink and follow the waste pipe to where it passes through the wall. A gap around the pipe can let a rat into the back of the cupboard, where it can move unseen. If you’re searching for “Rat Control Chennai” after spotting signs in your kitchen, check a few other possible entry points too. Look beneath the utility door, around damaged vent covers and along the roofline. Choose a repair that suits the opening. Seal gaps in masonry and fit damaged vents with sturdy metal mesh that still allows air to flow.

Start with the kitchen and utility area

Use a torch to look behind the sink cabinet and around the washing machine outlet. Check where each pipe actually enters the wall. Sometimes the visible hole is in the back panel of the cupboard, while the opening that leads into the home sits several centimetres behind it. Covering only the cupboard hole can leave the original route open.

For a gap in a masonry wall, ask a plumber or maintenance professional to fit a durable repair around the pipe. Larger openings may need securely fixed metal mesh, sheet metal or a masonry patch. If the gap surrounds a gas line or electrical cable, leave the repair to a qualified technician.

Check the gap beneath exterior doors

Close the back door or utility balcony door during daylight and look along its bottom edge. A strip of light is an easy way to spot a gap worth inspecting. Pay particular attention to the corners, where a worn door sweep can curl away from the frame.

If the threshold is uneven, a new sweep may still leave one corner exposed. Have the threshold repaired and fit a close-fitting, metal-reinforced door sweep. Once fitted, open and close the door to check that it moves freely and covers the gap across its full width.

Look beyond your flat to shared service shafts

In a Chennai apartment, the space behind your bathroom or kitchen wall may connect to a shared shaft carrying pipes between floors. If you repeatedly find signs near the same cupboard, photograph the pipe opening and show your building maintenance team exactly where it is. Ask them to inspect the shaft side as well as the opening inside your flat.

A shared shaft needs a coordinated repair. The maintenance team can arrange access, check neighbouring pipe openings and choose materials suited to the building. Keep access panels usable so plumbers can reach the lines later.

Inspect vents and roof edges in independent houses

If you hear scratching overhead, check the exterior from ground level. Look for a broken ventilator grille, loose mesh or an opening beneath the roof edge. A cover can look intact from the front even when one corner has pulled away from the wall.

Have damaged grilles repaired and loose mesh secured around the entire frame. For a ventilation opening, use a suitable metal screen that preserves airflow. Ask a professional to inspect roof-level openings or an enclosed ceiling where you suspect rats are already active.

What if rats keep coming back?

Note where and when you notice activity. “Scratching behind the sink after dark on three evenings” gives an inspector a clearer starting point than “rats in the kitchen.” In the meantime, transfer rice and other dry groceries to sturdy containers with tight lids, clear up spilled food and keep the kitchen bin covered. If rats are already indoors, the plan should address both their removal and the openings they use.
