30 g sugar

- Make fingernail sized balls of the paste that you find on the newspaper the next morning.

Important facts*
Boric Acid and Borax are NOT the same thing. Borax is Na2B4O7-10H2O and Boric Acid is H3BO3.
Borax can be used as a substitute for boric acid in this recipe – but it isn’t quite as effective as boric acid.
NB!
Borax is completely taboo for human use. It is said that an intake of 56 g borax can cause the death of an adult. Keep the cockroach balls that are used as roach bait out of the reach of children.
