Imagine you’re about to prepare your favorite meal in the kitchen when you notice a roach skittering across the counter. Gross! Luckily, this article will teach you how to get rid of roaches in the kitchen, whether you’re dealing with a one-time intruder or a full-blown infestation.
We’ll also explore the reasons why roaches are hiding in your kitchen, where they hide, how to identify an infestation, and how to prevent them from coming back to spread germs and haunt you.
Why Do Roaches Hide in Kitchens?
Roaches don’t specifically target your kitchen out of spite or malice. They are drawn to environments that meet their basic survival needs: food, shelter, and moisture. Kitchens, unfortunately, tick all these boxes, making them the perfect haven for these pests.
The moisture from your sink, combined with the inevitable spills, crumbs, and sometimes even food left out, creates an irresistible buffet for roaches. Add to this the warmth of appliances and dark hiding spots, and your kitchen becomes a cockroach paradise.
However, their presence in the kitchen poses a real threat to our health. That’s because roaches traverse through dumpsters and sewers before making their way into our homes. When they scurry across countertops and pantry shelves, they bring with them a host of pathogens that can lead to illnesses, such as:
- Dysentery
- Diarrhea
- Salmonella
- Staphylococcus infections
- Streptococcus infections
Where Do Roaches Hide in Kitchens?
Roaches are creatures of stealth, thriving in areas where they can stay hidden yet have easy access to food and water. Here are some common hideouts for cockroaches in the kitchen:
- Under the kitchen sink
- In drawers
- Inside kitchen cabinets
- Pantry
- Behind the dishwasher, fridge, and oven
- Near small kitchen appliances like toasters, coffee makers, and microwave ovens

Cockroaches are experts at staying out of sight, making their detection challenging. However, they do leave behind some telltale signs that can alert you to their presence. Here’s what to look out for:
- Allergy symptoms: If you notice that some members of your family are displaying allergic reactions, such as sneezing, runny nose, or itchy eyes out of nowhere, it could be a sign of cockroach allergens circulating in the area.
- Oily smell: A strong, musty odor could be a sign of a roach infestation.
- Cockroach droppings: Resembling coffee grounds or black pepper, finding droppings is a clear sign of a roach infestation. Be careful not to mistake them for termite droppings.
- Shed skins: As roaches grow, they shed their exoskeletons multiple times. Finding these is a sign that there are roaches growing in your kitchen.
- Nibbed food: If you notice holes or small chew marks on food packages and food itself, it could be the work of hungry cockroaches.
- Eggs cases: Finding oval-shaped egg cases (oothecae), either intact or hatched, is a sure sign of a breeding roach population in your kitchen.
- Live cockroaches: And finally, spotting live roaches, especially at night, can indicate that there are more in hiding.
How to Prevent Roaches in the Kitchen
The key to preventing cockroaches in the kitchen, be they German or American roaches, is to maintain a clean and dry environment. With the proactive steps below, you can make your kitchen less inviting to these nasty pests, saving yourself the hassle of dealing with an infestation:
- Don’t leave food out: Always store food in sealed containers and never leave leftovers uncovered.
- Vacuum the kitchen floor regularly: Crumbs and food particles on the floor can be a feast for roaches. If a vacuum isn’t enough, using one of the best steam cleaners to clean floors, cabinets, counters, and sinks also disinfects bacteria left behind by roaches.
- Wash the dishes: Leaving dirty dishes in the sink overnight provides food and moisture for any lurking roaches.
- Manage garbage wisely: Don’t leave garbage bins uncovered, and take the trash out daily. Consider moving the bins away from under the sink.
- Clean your kitchen cabinets: Crumbs and spills inside the cabinets can attract roaches.
- Inspect and seal cracks or crevices: Regularly check drain pipes under the sink for any gaps that roaches could use as entry points. Check out this video by Brittany Bailey to learn how to seal entry points around piping:
- Fix leaky faucets: Moisture attracts roaches, so address any leaks under the sink promptly.
- Cover the drain: You can cover the drain with a stopper overnight to prevent sewer roaches from entering through the drains.
- Manage pet food: Don’t leave pet food in bowls overnight, so it doesn’t attract roaches.
- Use essential oils: Spray a mixture of water and essential oils containing thymol or trans-cinnamaldehyde (like thyme and cinnamon oil) around your kitchen.
How to Get Rid of Roaches in the Kitchen
Despite your best efforts to keep your kitchen clean, roaches can still find their way into it. But you don’t have to panic just yet — there are some measures you can take to rid your kitchen of these nasty pests. However, bear in mind that battling roaches often requires a multifaceted approach.
Here’s what you can do to get rid of roaches in your kitchen:
- Use a boric acid mixture: Mix 1 cup of borax powder with 1 cup of sugar in 1 gallon of water, place this solution in trays, and distribute it around the kitchen, especially under the sink and inside cabinets. The sugar acts as an attractant while the borax is lethal to roaches.
- Employ store-bought bait: Roach baits contain attractants and insecticides that not only kill the roaches that eat them but also those that come in contact with them. Place these baits under the sink, around the trash area, and inside kitchen cabinets.
- Use roach traps: These traps use bait to lure roaches into a sticky substance they can’t escape from, killing them. Place the roach traps in areas where roaches tend to roam, such as inside kitchen drawers and near food storage areas.
- Sprinkle baking soda: Baking soda creates gas inside the roaches’ digestive systems when they eat it, killing them. Sprinkle it around your kitchen.
- Pour boiling water: This is a simple method for immediate roach control. Pour the boiling water down the drain in the kitchen sink to eliminate sewer roaches that may be hiding there.
- Call the pros: If the infestation is too severe, it might be better to call in a cockroach exterminator. They can use insecticides with pyrethrin or resmethrin and employ insect growth regulators (IGRs) for a long-term solution.
Keep taking preventive measures even if there’s already an infestation in your kitchen. This will make your kitchen less attractive to new roach intruders but also ensure that the existing population doesn’t have the resources to continue reproducing and growing.
