Cockroaches eat feces, dead animals, sour beer, and even their young ones. There are not many species in the world as nasty as these creatures.

They are only next to dust mites when it comes to causing allergies.

Cockroach infestation is a major domestic problem. These nasty guests just check in, but do not check out. Many cockroach repellents are available in the market. Unfortunately, most of them are loaded with chemicals that may harm human beings.

      Will Clovite really kill roaches? Our neighbor moved and the homeowner sent orkin out to spray... 2 weeks later, my house is infested. The man whom sprayed is a friend of mine, and he said the reason is all the roaches left and came to my house.

      I own my home, and our houses are not that close, but close enough I guess.

      My son has allergies real bad, and I can not have any chemicals in my home, but I do have a sister who owns a couple of mini horses that uses clovite. If it works, then I will try it. Please be truthful.

      Thank you

      I see this is a bit dated, but would mixing multiple oils listed be even more effective? Say, citrus, tea tree and clove? If not, what mixtures would be best? Thanks.

      If you currently have a cockroach problem cook with garlic everyday for a month and once a week after that month to keep cockroaches uninterested

      or

      Boil a pot with a tablespoon of minced garlic and the scent will ride the vapor around the kitchen with the same effect.
