Hi Mona, seal up all cracks and gaps that you can find, make sure they don'e have a source of water, and The most popular and effective natural cockroach killer is diatomaceous earth. It is non-toxic to humans and kills roaches when they come into contact with it. Sprinkle the diatomaceous earth around areas where roaches travel and frequent.

Boric acid or Diatomaceous earth or Sevin granules. I sprinkled Sevin granules all over my porch and in my garage because I had some handy (bought for ant hills). GONE!
