The kitchen and bathroom are the two rooms in the house that cockroaches are attracted to the most. That is because cockroaches are always in search of food and water just like every other living creature, which leads them to your kitchen for a snack.
There are several things you can do to get rid of roaches in your kitchen, and make sure that they never come back. The first thing you need to do is choose your weapon of choice and pick a pesticide to put down throughout the kitchen (recommendations below).
Then you will need to check for and fill any small cracks or crevices in your home that cockroaches use as entryways. The final step is to clean the kitchen thoroughly, and keep it clean, to deter more cockroaches from coming back.
Pick your cockroach poison
The thing you need to do first is put down a cockroach killer throughout your kitchen. You have several options here but there are differences between them which I will describe. You want to apply the roach killer everywhere you can in the kitchen. For example, along the floorboards, in the cabinets, under the refrigerator, stove, and dishwasher. Basically, everywhere that roaches can scurry you want to make sure is covered with pesticide.
Boric acid: This is usually my first recommendation (but not for the kitchen) because it is cheap, highly effective, leaves little residue, and is not harmful to your pets or children. It is a chalk colored powder that comes in a bottle and you just clip off the top and that lets you inject the powder all along the areas that you want to. I like to inject a little along the baseboards of the wall since that is where roaches like to crawl. The drawback is that boric acid powder can be easily moved by wind or foot traffic and doesn’t stay in place for a long period of time.
Cockroach gel or paste: Cockroach gel is also extremely effective at killing cockroaches and is actually my favorite cockroach killer for the kitchen. Cockroach gel’s advantage over boric acid powder is that it does not get dispersed as easily (one application can work for a couple months). But it’s drawback is that it leaves a residue behind on whatever surface you apply it to. Some of these gels can discolor your floor with a black or brown mark, which is fine in the garage or basement, but obviously not in the kitchen. So be careful with that.
Here is a little trick that one of my readers actually told me about: Apply the cockroach gel to a small piece of cardboard and then slide the cardboard under your refrigerator, put it in the cabinet under the kitchen sink, or wherever. That will save your floors and counters from getting stained.
Bait traps: Traps are great if you don’t have a big cockroach infestation, and perhaps if you have only seen a few of them. You can scatter several of them around the kitchen, and they are easy to slide behind the refrigerator and other large appliances. If you have a lot of cockroaches, I would recommend that you go with one of the other two choices, however. Especially in the kitchen where roaches are attracted to the most, you are better of going with gel.
Clean your kitchen thoroughly
In order to get roaches out of your kitchen, you absolutely have to keep it clean. Use a detergent or diluted bleach solution to thoroughly clean all your kitchen surfaces. All along the floors and countertops. Clean inside and on top of the stove.
Move your refrigerator and clean in that area as well. Under the fridge is a forgotten place that can build up dirt and debris that roaches can feed on. Roach feces often accumulate there, as well. And wipe down the inside of the fridge, too. You wouldn’t think roaches could get inside the fridge but often they can. Any residual food or grime can be smelled by cockroaches and it will attract them.
I prefer cleaning with bleach because it helps to mask any smells that bring in the roaches. It is a great bacterial disinfectant, as well. Make sure you do this regularly and keep your kitchen clean at all times. If there’s no food or water for them to access, cockroaches will have no reason to come in your kitchen any more.
Block cockroach entryways to your kitchen
Cockroaches have to get in your kitchen somehow, and that is usually through small cracks or crevices in the structure of your home, or a door that does not seal tightly shut. To go the final mile, you need to locate and use caulk to fill these holes. It’s a good idea to go ahead and seal the entire flooring area around your kitchen with caulk.
Where the linoleum or tile meets the wall, go ahead and spread a layer of caulk all the way around the kitchen to seal in places where the roaches might get in. This might sound like a big job, but it really doesn’t take that long. Make sure you caulk inside the cabinets and where the cabinets meet the wall, too.
Check the doors and windows in your home are properly sealed to keep roaches out. Window and door seals are prone to have small cracks because of their frequent opening and closing. Fixing these will also save on your utility bills, as well as keep roaches out.
Following these steps should be enough to get rid of all the cockroaches in your kitchen. It’s really very simple. Just clean the kitchen thoroughly and keep it clean. Use cockroach gel to kill the roaches already infesting your kitchen. The cockroach poison may take several days to start working, but you should start to find dead cockroaches fairly quickly.
It may take a few weeks to get rid of all the cockroaches because as the adults die, there are cockroach eggs hatching new baby cockroaches. But the cockroach nymphs will die before they are able to reproduce, ending their life cycle. And hopefully your kitchen will be cockroach free ever after.
