Imagine opening your microwave to warm up some leftovers, only to find that it’s not just your food that’s getting heated up — a bunch of cockroaches are scurrying around! Gross, right? It’s a nightmare no one wants to experience, but it happens. Cockroaches love warm, cozy places, and your microwave is just that.
If you’re dealing with an unexpected infestation in your kitchen appliance, don’t stress — we’ve got you covered. In this blog post, I’ll walk you through the easiest, most effective ways to get those pesky critters out and keep them from coming back. Let’s dive in and make your microwave roach-free!

Why Cockroaches Infest Microwaves
Before we get into how to deal with cockroaches in your microwave, let’s talk about why they might be there in the first place. It’s not like they’re just hanging out because they like the décor, right? Cockroaches are drawn to warmth, moisture, and food — all things that microwaves can provide.
Warmth and Hiding Spots
Microwaves give off heat when they’re in use, and cockroaches are creatures that love warmth. They seek out warm places to rest, especially in colder weather. A microwave, when not in use, can still retain some residual heat, making it a perfect spot for cockroaches to hang out, especially during the night when they’re most active.
Food Crumbs and Spills
Microwaves are also prime real estate for food particles. If you’re not careful, crumbs or spilled liquids can make their way into the microwave. These remnants are a feast for cockroaches, and once they’ve found the food, they’ll keep coming back for more. It doesn’t take much for these little pests to be attracted to your appliance, and even the smallest crumbs can become an all-you-can-eat buffet.
Moisture
Another thing cockroaches need is moisture. They don’t necessarily drink water the way we do, but they do need moisture to survive. Microwaves, especially those used to heat up steamy food, provide just enough moisture for roaches to stay hydrated. This makes them even more likely to take up residence in your microwave, making it a breeding ground for them.
Lack of Regular Cleaning
Sometimes, the reason cockroaches show up is simply because the microwave hasn’t been cleaned in a while. Food particles can accumulate over time, and that’s exactly what cockroaches are looking for. If you don’t clean your microwave regularly, it could end up attracting a roach or two. The messier your microwave, the more inviting it becomes to these unwanted guests.
Now that we understand why cockroaches like microwaves, let’s move on to how you can kick them out for good.
How to Remove Cockroaches from Your Microwave
Getting rid of cockroaches from your microwave isn’t as tough as you might think. There are simple steps you can take to eliminate them and keep your microwave pest-free.
Step 1: Turn Off the Microwave and Unplug It
The first thing you need to do is turn off the microwave and unplug it from the wall. This is important for your safety, as you’ll be cleaning it and potentially using cleaning solutions. It’s also a good idea to leave the microwave unplugged while you’re cleaning and inspecting it to avoid any accidents.
Step 2: Remove All Food and Debris
Once the microwave is off, take out anything inside it — food, containers, or any leftover bits that might attract cockroaches. Inspect the microwave thoroughly to make sure there are no crumbs or food particles hiding inside, especially in the corners or around the door seals. Use a soft cloth or a vacuum cleaner to pick up any debris. Clean up all the visible food remnants before moving to the next step.
Step 3: Inspect the Microwave for Roaches
Now it’s time to do a full inspection. Look inside the microwave and around it, paying attention to areas where cockroaches might be hiding, like the vents, the door edges, and the back of the microwave. You might also want to check behind or under the appliance, as roaches tend to gather in those dark, hidden places. If you spot any roaches, you’ll need to deal with them before continuing with the cleaning.
Step 4: Clean the Microwave with Soap and Water
Next, it’s cleaning time. Mix some mild dish soap with warm water in a bowl. Use a sponge or cloth to wipe down the inside of the microwave, paying special attention to any areas where food may have spilled. Make sure you get into the nooks and crannies. You can also remove the turntable and wash it separately. Cleaning the microwave thoroughly helps to remove any lingering food particles or smells that might attract roaches again in the future.
Step 5: Use Roach Traps or Natural Repellents
After cleaning the microwave, you’ll want to prevent any roaches from coming back. One way to do this is by using roach traps. These traps are specifically designed to lure and capture cockroaches. Place a trap near the microwave or in the kitchen area, where roaches are most likely to travel. You can find these traps at most hardware or grocery stores.
If you prefer a more natural solution, try using essential oils like peppermint, eucalyptus, or tea tree oil. Cockroaches hate these smells, so you can create a DIY repellent by mixing a few drops of essential oil with water in a spray bottle. Lightly spritz the areas around the microwave to keep roaches at bay.
Step 6: Seal Entry Points
Now that your microwave is clean, it’s time to think about how roaches might be getting inside in the first place. Cockroaches can squeeze through the tiniest cracks, so check the microwave’s seals, vents, and any gaps where the microwave might meet the wall. If you notice any cracks or gaps, seal them with some silicone caulk to prevent future infestations.
Step 7: Keep the Area Clean
To make sure roaches don’t return, keeping the area around your microwave clean is essential. Wipe down the kitchen counters, sweep up any crumbs, and make sure there’s no standing water in the kitchen. Roaches are more likely to come around if they find food or moisture sources nearby. Regularly cleaning your kitchen will help eliminate these attractions and make your space less inviting to roaches.
Step 8: Check for Other Infestations in the Home
If you’re still seeing roaches in the microwave, it might be time to check for a larger infestation. Cockroaches don’t just live in microwaves — they could be hiding elsewhere in your home, like in cabinets, under the sink, or in dark corners. You may want to consider calling a professional pest control service to assess the situation and deal with a potential infestation before it gets worse.
How to Prevent Cockroaches from Coming Back
Getting rid of cockroaches in your microwave is just half the battle. The other half is making sure they don’t return. Luckily, there are simple steps you can take to keep your microwave roach-free for good.
Regular Cleaning is Key
One of the easiest ways to keep cockroaches out of your microwave is by regularly cleaning it. Wipe down the inside after every use, especially if you’ve heated food that has spilled or left crumbs behind. The cleaner you keep your microwave, the less likely it will be to attract pests. If you find food in the microwave that you didn’t put there, it might be a good idea to give the appliance a more thorough cleaning.
Keep the Kitchen Dry
Cockroaches need moisture to survive, so keeping your kitchen dry is another effective way to prevent them from coming back. Make sure there are no leaks around the sink, and keep the area around your microwave dry. If you notice condensation or moisture buildup, wipe it up right away.
Store Food Properly
Store all food in airtight containers to make sure there’s nothing attracting cockroaches. Don’t leave food out overnight or on the counter. Cockroaches are always on the lookout for easy food sources, so taking the extra step to store food properly can keep them away from your microwave and kitchen.
Seal Gaps and Cracks
Check the kitchen and microwave area for any cracks or gaps where cockroaches might be entering. Seal these areas with silicone caulk or another appropriate sealant to make sure the pests can’t get inside. This is an easy way to make your kitchen less inviting to cockroaches.
I hope these steps help you get rid of those pesky roaches from your microwave and keep them from coming back. Dealing with pests isn’t fun, but with a little effort and maintenance, you can create a clean and pest-free kitchen. Remember, a clean microwave is a happy microwave!
