Rats in the house are a big problem. In this guide, we show you how to use rat kill cake the right way. They chew wires. They spoil food. They spread germs. One easy fix is a rat kill cake. It is cheap. It is easy to use. You do not need any tools. We keep it simple. No hard words. Just clear steps you can follow today.
What Is Rat Kill Cake?
Rat kill cake is a small block. It looks like a dark brown or black cake. It has a poison mixed inside. Rats like the smell and taste. So they eat it.
The poison works slowly. It does not kill the rat right away. This is by design. It gives the rat time to walk back outside before it dies. So you do not find dead rats stuck inside your walls.
Most rat kill cakes, like Mortein Rat Kill Cake, work in one feed. This means the rat only needs to eat it once. You do not need to keep refilling it many times.

DIY: How To Use Rat Kill Cake In House (Step By Step)
Step 1: Find rat spots first
Look for signs of rats. Check for droppings, chew marks, or small holes. Common spots are:
- Behind the kitchen fridge or stove
- Near the kitchen sink
- Inside cupboards
- Along the wall edges
- Near the main door or drain pipe
Step 2: Break the cake into small pieces
Take the rat kill cake out of its pack. Break it into 4 to 6 small pieces. Small pieces work better. Rats can carry them and eat them fast.
Step 3: Wear gloves
Do not touch the cake with bare hands. Use gloves, or use a plastic bag over your hand. This keeps your hands safe and keeps your smell off the bait.
Step 4: Place the pieces in the right spots
Put the small pieces in the areas you found in Step 1. Place them:
- Along the wall, not in the middle of the room
- Near rat holes or burrows
- In dark, quiet corners
- Away from food, plates, and cooking areas
Step 5: Keep it away from kids and pets
This is very important. Place the cake only in spots your children and pets cannot reach. Some good options:
- Behind heavy furniture
- Inside a small bait box (many kits come with one)
- On top shelves that kids cannot reach
Step 6: Leave it and wait
Do not move the cake every day. Let it sit for a few days. Rats need time to find it and eat it.
Step 7: Check and refill
After 3 to 4 days, check the spot. If the piece is gone or half-eaten, that means rats found it. Place a fresh piece in the same spot. Keep doing this until you stop seeing rat signs.
Step 8: Clean up safely
If you find a dead rat, do not touch it with bare hands. Use gloves and a plastic bag. Put the rat in the bag, tie it, and throw it away outside your home. Wash your hands well with soap after.
Step 9: Store the rest safely
Keep any unused rat kill cake in a cool, dry place. Keep it in its original pack. Store it away from food, and away from children and pets. Do not leave it in the sun or near heat.
Safety Tips To Remember
- Rat kill cake is a poison. It is not food.
- Never use it in kitchen areas where food is kept open.
- Wash your hands after you touch it, even with gloves.
- Keep pets like dogs and cats away from bait spots.
- If a child or pet eats it by mistake, call a doctor or vet right away. Take the pack with you so they know what was eaten.
