If you have pests, such as cockroaches, mice, or rats in your home, there's no need to purchase and use toxic, harmful poisons to get rid of the infestation. Instead, you can mix up a simple paste using common household ingredients. Your home will be pest-free within a matter of weeks.

Step 1

Go outside or open a window, so that you're in a very-well ventilated area. Although boric acid isn't harmful to humans, it does irritate the breathing passages of some individuals (especially those with asthma or chronic bronchitis), so it's a good idea to be in an open, non-enclosed space.

Step 2

Pour one cup of boric acid powder into the disposable bowl. Use the disposable fork to break up any clumps in the boric acid powder.

Step 3

Decide on which mix-in you want to use for your boric acid paste. Rats prefer savory items, so chicken broth should be used. Roaches like oily foods, so peanut butter should be used for roach infestations. Sweet mix-ins like molasses or honey should be used for homes with ant infestations.

Step 4

Add the mix-in of your choice (as determined in step three), an eighth of a cup at a time.

Step 5

Mix well with the disposable fork after each addition of the mix-in to the boric acid powder. Mix until a thick paste is formed.

Step 6

Adjust your recipe as needed. The boric acid paste should be slightly thicker than cookie dough. If your paste is too thin, add more boric acid powder. If, on the other hand, the paste is too thick, and is difficult to mix properly, add in some more broth, honey, or peanut butter.

Step 7

Continue mixing and adding either boric acid powder or mix-in until you reach the desired thick cookie dough consistency.
