Answer 1

Things You’ll Need:

Kitchen and bathroom cleaners

A vacuum cleaner or shop vacuum with a HEPA filter

Caulk and foam insulation

Light colored paint

Boric acid powder

Non toxic bug spray

Step1

Take all food and dishes out of cabinets and drawers. Put food in sealed containers. Clean all counter tops, inside cabinets, drawers, and in any dark places in your kitchen and bathrooms with mild soapy water. Put trash outside of the house. Vacuum all carpets and other floors making sure to clean in corners and along walls.

Step2

Fill holes and seal cracks in exterior walls and floors with caulk or foam insulation so roaches can't get in from outside. Let the caulk and foam insulation dry and set completely. Don't use glue products, roaches sometimes eat glue. Dry up any water that shouldn't be inside or outside of your house. Roaches can live a long time without food, but they need water regularly.

Step3

Paint inside of cabinets and drawers and other dark places if possible. Let the paint dry completely. Roaches will sometimes avoid hiding in dark places if they are painted a light color. Try not to use paper to line cabinet shelves, if there’s any spaces under the paper, they may hide there.

Step4

Apply boric acid (do not breath in or ingest boric acid and its recommended to use rubber dish gloves and a quality dust mask when using boric acid). If your house is infested with a lot of roaches, you may want to leave for about three days with your family and pets after you do this. Sprinkle onto counter tops, in cabinets, in empty drawers, under your stove and refrigerator, and in any dark place roaches may hide. Spread it on your kitchen and bathroom floors. Sprinkle some along the walls in the living room, hallways and bedrooms. Make sure to put some around entry doors too. You can also sprinkle the powder outside around the foundation of your house. When you leave, make sure there are no lights on in your house. The roaches will come out when it is dark and walk through the boric acid looking for food. They will ingest the powder as they eat food and when they clean their legs and antenna with their mouths.

When you come home, carefully cleanup as much of the powder as you can with a wet rag. Vacuum all of the powder that remains. You can leave some of it in dark places, under the stove and refrigerator and where you know roaches hide. Don't leave any where food is stored or where kids or pets can reach and touch the powder. Then clean your house thoroughly with mild soap and water.

If you don't have many roaches, you don't have to leave for three days, just sprinkle the boric acid in dark places and where you know roaches hide and under the stove and refrigerator. Don't put any where food is stored or where kids or pets can reach and touch the powder.



Step5

If you see a roach later, just spray it with a mild solution of soap and water mixed together in a pump spray bottle. It’s easier to clean up and a good quality soap will kill roaches just as good as toxic bug spray. If you feel you need to use bug spray, try to use one that is non toxic.

____________________

Try to use non toxic cleaners and pesticides.



Using a stronger solution of soap and water in a pump sprayer as a cleaner and roach killer works better.



The more you clean before and after this boric acid treatment, the more roaches you will kill.



Vacuuming in as many places as you can before and after this treatment, also helps to lower roach populations.



Using a quality dust mask is recommended. Although boric acid is generally not considered to be much more toxic than table salt.



Sprinkle gently and try not to let the fine powder float in the air.

Answer 2

We just sprinkled dry borax under our cabinets, after removing the front plate of our toe kick, then replaced toe kick.  Works great. Did that 4 or 5 years ago and it's still effective.  

It's also a good idea to plug up any holes in your floors or cabinet bases where pipes go through.  Stuff them full of size 0000 steel wool around the pipes to keep roaches from coming in.  

Answer 3

I made my own "bait"

Peanut Butter and Boric Acid

Mix LOTS of boric acid with peanut butter, make it a paste.

It works well!

Answer 4

Keep in mind that you are killing more than roaches with these experiments. So don't do them.
