How to Get Rid of Rats & Mice in Delhi (2026) — Without the Poison Risks

Rat or mouse? Tell them apart before you do anything

People call everything a ‘chuha’, but the type matters, because it changes where you trap and what size trap you use. In Delhi homes you’ll mostly meet three.

The house mouse is the small one — body about the length of your thumb, big ears, a thin tail, droppings like grains of rice. It lives indoors, nests in clutter, in the back of the wardrobe, behind the fridge, inside that storeroom full of old DDA-flat junk. It breeds fast and you usually have more than one.

The brown rat — the sewer rat, Rattus norvegicus — is the big heavy one with a blunt nose and a tail shorter than its body. It comes up through drains, broken sewer lines and gaps near the kitchen waste pipe. This is the one you see in older parts of town — the back lanes of Chandni Chowk, the godown belts of Sadar Bazar and Khari Baoli, ground-floor shops in Lajpat Nagar. It digs burrows along compound walls and under the kitchen platform.

The roof rat is the climber — slimmer, pointed nose, tail longer than its body. This is the one running along the cable tray, in the false ceiling, in the loft over the kitchen, across the boundary wall into a first-floor flat. If your scratching comes from above you at night, it’s almost always a roof rat, not a mouse.

Why bother identifying? Because a mouse will walk into a small snap trap set flush against a skirting board, while a heavy brown rat needs a bigger trap and usually an outdoor bait station near its burrow. Set the wrong thing in the wrong place and you’ll spend two weeks wondering why nothing’s working.

Why you should NOT just scatter poison indoors

This is the part nobody at the kirana shop will tell you when they sell you that ₹40 packet of blue pellets. Indoor rodenticide is the single most common mistake I see in Delhi homes, and it backfires in four separate ways.

One — the smell. Poison doesn’t kill instantly. The rat eats it, wanders off, and dies a day or two later in the place it feels safest: inside a wall cavity, above the false ceiling, behind the kitchen cabinet, in the AC duct. You cannot reach it. For the next two to three weeks you live with a thick, sweet rotting smell that no room freshener touches, and in a Delhi summer it’s far worse. People have broken open false ceilings and chipped tiles trying to find one dead rat. That alone is reason enough to keep poison out of the house.

Two — the danger to your family and the street. Most shop rat poisons are anticoagulants. A child who picks up a stray pellet, or a dog or cat that eats it, is in real trouble. Worse is secondary poisoning: a poisoned rat staggers out into the lane, a street dog or a kite or an owl eats it, and the poison passes up the chain. India’s rodenticides are controlled by the Central Insecticides Board & Registration Committee precisely because they’re dangerous when used carelessly — they’re not meant to be flung around a kitchen floor where a toddler crawls.

Three — bait shyness. Rats are cautious and they’re smart. If a few of them get sick and survive, the colony learns to avoid that bait entirely. Now you’ve trained your rats to ignore the one tool you were relying on, and the next product works even worse.

Four — and this is the big one — poison never fixes how they got in. Say it does kill the rats inside. Fine. The gap under the kitchen door is still there. The hole where the AC copper pipe goes through the wall is still open. The cracked drain cover is still cracked. So a fresh rat walks in next week and you’re back to square one, this time with a poison habit and no actual repair done. Poison treats the symptom and ignores the disease.

The method that actually works — step by step

Professionals call it integrated rodent management. In plain terms it’s four things done together, in order. Do them properly and you don’t need indoor poison at all.

Step 1 — cut the food and water. Rats stay where they eat. Move dry grain, atta, rice and pulses into steel or thick-glass containers with tight lids — not the flimsy plastic ones they chew straight through. Don’t leave the dog’s food bowl out overnight. Take the kitchen bin out at night and keep it lidded. Fix the dripping tap under the sink; a rat can live off that drip alone. This step won’t kill anything, but it makes your traps the most attractive meal in the house.

Step 2 — exclusion, the part that actually ends it. This is sealing every way in. A house mouse fits through a gap the width of a pencil; a young rat through a two-rupee-coin hole. Stuff gaps with steel wool packed tight and then seal over it — rats chew through foam, silicone and plaster, but they won’t chew steel wool. Fit a door sweep or brush strip on the gap under the main door and the kitchen door. Put metal mesh over drain mouths, the kitchen exhaust outlet and any open vent. Seal around pipe sleeves — the AC pipe, the water inlet, the gas line. This is the unglamorous work that decides whether they come back.

Step 3 — snap traps, indoors only. Inside the house, a good old snap trap beats poison every time, because the rat dies where you can see it and remove it — no smell in the wall. Set traps flush against walls with the trigger facing the skirting, because rats run along edges, not across open floor. Bait with something sticky they can’t grab and run — a smear of peanut butter works far better than a loose piece of cheese. Use several at once; one trap for a colony is pointless. Glue boards are sold everywhere but they’re slow and cruel, and a strong rat just drags it off — I don’t recommend them indoors.

Step 4 — tamper-proof bait stations, outside only. There is a place for bait: in a locked, tamper-proof station, placed outdoors along the compound wall, near burrows, by the gate — never loose, never indoors, never where a child or pet can reach. The station knocks down the population trying to get in from the lane while your indoor traps and proofing handle anything already inside. That’s the difference between how a kirana-shop packet gets used and how a professional uses the same active ingredient safely.

Real rodent control cost in Delhi (2026)

Here’s honest 2026 pricing. A one-off rodent visit means inspection, trap placement, sealing the obvious gaps and an outdoor bait station where it’s safe. For a recurring problem — or any food business — an annual contract (AMC) with scheduled visits works out cheaper and actually keeps them gone.

Treat anyone quoting ₹300 to ‘finish all your rats today’ with suspicion — that’s almost always one loose poison packet flung behind the fridge, which is exactly the dead-rat-in-the-wall scenario you’re trying to avoid. Real rodent work takes inspection time and at least one follow-up.

Why rats are a real risk, not just gross

People tolerate a rat far longer than they should because it feels like an embarrassment rather than a hazard. It’s a hazard.

Fire. Rats’ teeth never stop growing, so they gnaw constantly to file them down — and electrical cable is a favourite. Stripped wiring inside a wall or behind an appliance is a genuine short-circuit and fire risk. Plenty of ‘mystery’ electrical faults in older Delhi homes trace back to a rat chewing the insulation. They’ll also chew through pipes, gas lines and the wiring loom of a car parked in the basement.

Food and surface contamination. A rat doesn’t just eat your grain — it walks through the drain and then across your kitchen platform, leaving droppings, urine and hair on every surface. You end up throwing away far more food than it ever ate, plus you’re prepping on a contaminated counter.

Disease. This is the serious bit. Rodents spread leptospirosis through their urine — a real monsoon risk in a city that floods — along with salmonella and other bugs. The National Centre for Disease Control tracks rodent-borne illness in Indian cities for a reason. A scratching noise in the ceiling is annoying; a sick child is not.

Restaurants, kirana shops & cloud kitchens — you need an AMC

If you run any kind of food business, a one-off visit isn’t enough — and it isn’t just about hygiene, it’s about your licence. The Food Safety and Standards Authority of India expects food premises to have an active pest-control programme, and an auditor will ask to see the records: dates of visits, what was found, what was done, a map of where the bait stations sit. A verbal ‘haan, we get it done sometimes’ will not pass.

A proper rodent AMC gives you scheduled visits (usually monthly for a busy kitchen), tamper-proof stations numbered and mapped, a monitoring log, and a signed service report each time. That paperwork is what keeps your FSSAI file clean. For a cloud kitchen packed into a tight industrial pocket — the Okhla and Naraina belts are full of them — this matters even more, because your neighbours’ rats become your rats the moment one kitchen slacks off. An AMC from around ₹4,999 a year is cheaper than one failed audit.

Keep them out for good — the proofing checklist

Killing the rats inside is half the job; the half that actually lasts is closing the doors they came through. Here’s where they get into Delhi homes, and roughly how well each fix holds up if you do it properly. The bars below are simple — longer and green means it reliably keeps rodents out; shorter and amber means it helps but won’t hold on its own.

The common Delhi entry points, in the order we usually find them:

Areas we serve across Delhi

We do rodent control across most of Delhi — South Delhi (Lajpat Nagar, Greater Kailash, Saket, Malviya Nagar, Khanpur), the old-city and trade belts where brown rats are worst (Chandni Chowk, Sadar Bazar, Khari Baoli, Karol Bagh), the West and Central pockets (Rajouri Garden, Naraina, Patel Nagar), East Delhi (Laxmi Nagar, Mayur Vihar, Preet Vihar) and the North Delhi blocks. If you’re in an older DDA colony with shared drains and a common boundary wall, you’re exactly the kind of place where the trap-and-exclude method earns its keep — sorting one flat without proofing the shared gaps just sends the rats next door and back.
