Natural remedies for cockroaches

By using special pesticides, you will probably notice results almost immediately, but not everyone is prepared to protect their family from the toxic chemicals that come with it. So, here is how to get rid of cockroaches with homemade remedies, which are the most effective natural, harm-free solutions for a cockroach infestation.

Get rid of cockroaches with diatomaceous earth

Diatomaceous earth is one of the safest, pet and kids friendly repellent that you can use. But to have a full effect, you need to follow the below steps:

  1. Clean your home thoroughly.
    Maintaining a sanitised environment will lower your chances of getting infested in the first place. If it’s already happened, though, this should be your first step. Make sure to go behind all the appliances, sofas, as well as clean under the rest of your big and small furniture.
  2. Mop and dry any damp areas in your home.
    If you have any damp places, like under the matt in the bathroom or another spot somewhere in the kitchen, make sure that everything is dry before you apply the diatomaceous earth. If the area is even slightly wet, the Diatomaceous Earth will not kill the insects. Go around the house and check if there are any cracks, which have the potential of being an entry point and seal them for good.
  3. Go through all the places, where you have seen the cockroaches.
    Make sure to dust the spots lightly, because the pests won’t step on it if the product has been heavily applied. Cover all the places from where you think the cockroaches might have sneaked through inside the house, as well as areas, where food gets dropped often on the floor.
  4. Go outside and apply the Diatomaceous earth at the bases of your house.
    Check which applicators are better for your situation. What you decide to use will depend on whether you live in a place with a dry or damp climate.
  5. Let the solution sit until the infestation is over.
    If the product gets washed away, apply it again. After you have successfully got rid of all the cockroaches, you can either clean the Diatomaceous Earth up or leave it as a prevention against future infestations.

Use baking soda to kill roaches

Baking soda is one of the most multifunctional products ever created, so it’s no surprise that it has the ability to get rid of cockroaches, as well. The best method is if you mix the soda with some sugar, first.

The smell of sugar will bring out the roaches, tempting them to eat from the mixture, without noticing the baking soda. After that, when they go to drink some water, a reaction with the soda will cause their stomach to burst. Cockroaches often feed on their dead comrades, so a chain reaction of death will follow.

Here is how to proceed:

  1. Mix equal parts of sugar and baking soda in a lid or a dish.
  2. Place another dish or a lid close to the first one and fill it with water.
  3. Refill the containers with more bait and water when the dead roaches start to appear.
  4. Place a couple more dishes around the places, where roaches usually gather.
  5. Repeat until you are cockroach free.

Getting rid of cockroaches by using catnip

Almost anyone who has cats also has catnip. And even if you don’t have, you can easily purchase it. It’s one of the most effective home remedies against cockroaches and it’s really easy to use.

  1. Boil around 1l of water.
  2. Place the catnip in the water and let it boil for around 10 minutes
  3. Turn off the heat and let the solution cool down.
  4. Put it in a spray bottle and apply it all over your property.

How to kill cockroaches with a boric acid mix

This method is similar to the one with the baking soda and sugar. You have to make a mixture of boric acid and flour, fill a couple of lids with it and place it where you have seen the most activity. The flour will attract the roaches and the acid will kill them. Just like the previous solution, even if the mix is deadly for the pests, it’s completely harmless to humans and pets.

Essential oils against cockroaches

It might sound unbelievable to you, but essential oils are actually a proven cockroach repellent. Their strong smell disrupts the hunting path of roaches and if the oil concentration is strong enough, the substance will also kill them.

The smells, most hated by the cockroaches, are the these of lavender, peppermint, eucalyptus and tea tree oils. Either one of them should do the job, so just choose the one you like the most.

  • Apply the oil to a piece of cotton and wipe down with it all the places, where the roaches gather. Soak the surfaces up well with the oil of your choice.
  • The other way to do it is to mix a solution of 15 oil drops and around 10 ounces of water. Put the solution in a spray bottle and spray all the entry points and dark areas.

Cockroach repellent with household detergents

Another easy solution against these annoying pests includes a simple mixture of dish soap and water. Just like most insects, cockroaches breathe through their skin, so spraying the detergent on them will suffocate the pests instantly. The one thing you have to keep in mind is that it works only if the roach is directly sprayed. The method is not recommended if you need to get rid of a whole nest unless you have the patience to spray each cockroach individually.

All of the above-mentioned remedies are most effective against a mild infestation or singular roaches. If you have a serious problem with cockroaches, the wiser option is to trust a professional company to take care of the problem. Most specialists use child and pet-friendly solutions and are familiar with every type of cockroach invasion that there is.
