You can also try the following ideas:
- Diatomaceous earth is a safe alternative which can be sprinkled in areas where roaches congregate, especially hidden areas such a cabinet tops and behind appliances. Harmless to people, the tiny particles cut the waxy exoskeleton and kills the insect within 48 hours. For a week or so after the treatment, the dehydrating insects will search more actively for water. Therefore, do not be surprised if you see roaches more often after the treatment. Most roaches should be killed within two weeks of application. Click for more info or to purchase diatomaceous earth
- Catnip is a natural repellent to cockroaches. The active ingredient is nepetalactone, which is non-toxic to humans and pets. Small sachets of catnip can be left in areas of cockroach activity. Catnip can also be simmered in a small amount of water to make a "catnip tea" which can be used as a spray to apply around baseboards and behind counters. This natural repellent should only be used in homes without cats!
- Keep a spray bottle of soapy water on hand. Spraying roaches directly with soapy water will kill them.
- In an empty one pound coffee can, place 1 or 2 pieces of bread which have been soaked thoroughly with beer. Place in areas known to have roach infestations.
- It is a little known fact that roaches like high places. If you put boric acid on TOP of your kitchen cabinets (not inside), if space allows between ceiling and cabinets, the roaches will take the boric acid to their nests, killing all of them. Boric acid is toxic by mouth - keep away from children and pets.
- Leave bay leaves, cucumber slices or garlic in the affected area as deterrents.
