Methods for Exposing Rats to Smoke

Quck answer

Rats can be a nuisance and pose health risks. Here are some effective ways to smoke out rats:

1. Seal all entry points: Identify and seal any gaps or holes in your home or building to prevent rats from entering.

2. Remove food sources: Keep all food stored in sealed containers and clean up any spills or crumbs promptly.

3. Use natural deterrents: Peppermint oil, ammonia, and predator urine can deter rats from entering your property.

4. Set traps: Place baited traps in areas where rats are active, such as along walls or near their nests.

5. Consider smoke bombs: Smoke bombs can be used as a last resort to drive rats out of their hiding places.

Remember, it’s important to take proactive measures to prevent rats from entering your property and to address any infestations promptly.


Rats are carriers of up to 35 different illnesses that can be transmitted to humans, making them both harmful and damaging. However, eradicating an infestation is not always a simple task. Using a spring trap to eliminate rats is a slow process that also puts your fingers at risk. The most effective way to catch rats during daylight hours is by using a rat smoker. If you are skilled, you can construct your own.

Step 1

Locate the area of the insect fogger where the fog is released through a mesh.

Step 2

Fit the large radiator hose over the end of the fogger, completely covering the mesh. Make sure that the hose is long and flexible enough to allow you to direct the smoke as needed.

Step 3

Connect the propane tank to the fogger.

Step 4

Pour 1/2 cup of vegetable oil into the fogger’s reservoir.

Step 5

Locate the rat’s nest. Look for signs of a potential food source, as rats tend to live near their food. Search for footprints or droppings that may lead you to the nest. Once you find the nest, thoroughly inspect the area and identify all possible exits. Seal them off, but make sure to leave at least two open.

Step 6

Ignite the smoker. Using the attached hose, direct the smoke into one end of the rat’s nest while observing the exit. As the nest fills with smoke, the rats will come out.
