How to Get Rid of Cockroaches in Your Garage

Cockroaches In Garage Spaces? Here Is Our 6 Point Guide

Find the cockroaches and their hiding places.

The first thing you need to do is figure out where the cockroaches are hiding in your garage. You can plan your attack with greater accuracy when you know where they are.

Cockroaches are often found in dark and secluded areas.

They may be hiding in:

  • The crevices of walls,
  • In the corners of ceilings,
  • Under any appliances,
  • Under or in your car,
  • Inside trash in your garage,
  • Inside items you are storing in your garage.

It is important to inspect these areas closely when trying to find cockroaches in your garage.

Remove any visible eggs.

One of the most important things that you can do when getting rid of cockroaches is to remove any visible eggs. This will help stop the cockroaches from being able to reproduce, making it easier to get rid of them.

You can remove the eggs by using a vacuum cleaner or a broom. Be sure to get rid of the eggs in a sealed bag so that the cockroaches cannot get to them.

Clean your garage and do not store easily accessible food

Cockroaches are one of the most common pests globally, and they can be challenging to get rid of once they infest an area.

If you have cockroaches in your garage, one of the steps to eliminate them is to clean up the area and eliminate their food sources.

Start by sweeping up any dirt, dust, and debris. Then, wash all surfaces with a strong cleaner, paying particular attention to cracks and crevices where cockroaches like to hide.

Once you’ve cleaned the area, keep it clean by regularly sweeping and vacuuming.

Search for entry points and fill them

One of the best ways to cockroach-proof your garage is to search for and fill in any potential cockroach entry points.

Cockroaches are skilled contortionists and can squeeze through tiny spaces, even as thin as a dime.

As you’re searching for entry points, check both inside and outside your garage.

Once you’ve found all potential cockroach entry points, seal them up with caulk or another sealant. This will help keep cockroaches out of your garage and prevent them from infesting your home.

Entry points to your garage include:

  • Cracks in the foundation,
  • Gaps around doors and windows,
  • Vents,
  • Pipes,
  • Holes in screens.

Use cockroach traps with bait.

Cockroach traps are an easy and effective way to get rid of cockroaches in your garage.

Many different cockroach traps are available, but they all work by attracting the cockroaches with bait and then trapping them.

The bait is usually something sweet or oily, to which cockroaches are attracted to.

Once the cockroaches enter the trap, they can’t escape and will eventually die, especially if the bait is laced with a pesticide.

Not all cockroach traps are safe to use around children and pets. If you have kids or pets, do not use traps that are not marked as kid or pet safe.

Install a motion-sensor light for prevention

If you’re tired of dealing with cockroaches, you should consider installing a motion sensor light in your garage.

Cockroaches are naturally afraid of light, so the sudden blast of light will scare them away or into hiding. The first time I had to deal with cockroaches was in a hotel room on the West Coast of America. As soon as I switched the light on, they all scurried into hiding. It was the only thing that I could do to get some sleep!

Additionally, motion sensor lights can help to deter burglars and other intruders.

So if you’re looking for a simple way to keep your garage cockroach-free, installing a motion sensor light may be the solution.

Natural methods to get rid of cockroaches in your garage

If you’re dealing with cockroaches in your garage, there are a few natural methods you can use to get rid of them.

One option is to make a cockroach trap out of a container and some bait.

Cockroaches are attracted to food, so placing a bit of bait inside a container and then covering the opening with tape or another material will lure them in. Once they’re inside, they won’t be able to escape.

You can also try using diatomaceous earth, a natural substance that’s deadly to cockroaches. Just sprinkle it around your garage, and they’ll eventually die off.

Finally, you can also try using essential oils to repel cockroaches. Citronella, eucalyptus, and peppermint oil effectively keep cockroaches away. Simply place a few drops on a cotton ball and put it in areas where cockroaches are a problem.

How to prevent cockroaches from getting into your garage in the first place

Cockroaches like to hide in dark, moist places, so you can reduce the likelihood of them coming in by keeping your garage as clean and dry as possible.

Make sure to sweep and mop regularly, and avoid leaving food or garbage lying around.

You can also install screens over your garage door and windows and use cockroach traps to catch any roaches that do make their way in.

Professional Exterminator

If you have a severe cockroach infestation in your garage, you may need to hire a professional exterminator.

These exterminators use more powerful chemicals, killing many cockroaches at once.

Is it normal to have cockroaches in a garage?

Unless you’re one of those people who meticulously clean their garage regularly, there’s a good chance that you’ve got at least a few cockroaches scuttling around in there.

That’s normal.

Cockroaches are attracted to dark, cluttered spaces where they can find food and water – and garages often fit that bill.

If you’ve got cockroaches in your garage, the best course of action is to run through the strategies on this page.

Clean up any potential food sources (including pet food, spills, crumbs, etc.) and keep garbage cans tightly sealed. You may also want to invest in some cockroach traps or baits to help control the population. But don’t worry – a few cockroaches in your garage is normal.


If you have a garage, you probably have seen or at least heard about cockroaches living in them!

These pests can be challenging to get rid of and often require the help of a professional exterminator, especially if the cockroach infestation becomes severe.

However, if you have had cockroaches suddenly appear in your garage, there are some things you can do on your own to make your garage less hospitable for cockroaches and hopefully drive them away.

Follow the strategies listed on this page to help eliminate these unwanted guests from your garage.
