Some of Grandma’s remedies, believe it or not, actually work and are quite effective. Neem has been used as a home remedy to get rid of cockroaches and other house pests over the years. This item contains a lot of strong components that can kill those horrible insects. It can be found in oil or powder form.
If you plan on using it in oil form, mix a small part of neem oil with some water and put the mix in a spray bottle and spray it in places where you see pests.
And if you choose to use neem powder, then all you have to do is to sprinkle it in the areas where they usually stay, in the corners, and make sure you repeat the operation every morning. Let it stay during the night.
