For those who may need it….
1. Boric acid
2. One spoonful sugar
3.1 red or white onion
4. A little milk
5. 1 Egg
Mix it all up in to a paste and apply around your house/cupboards etc. remaining mixture put in bottle tops and keep out of your kids reach but where those roaches hide.
so where does one get this boric acid?
Tried this too.
Kafai, any chemist should have it in stock.
You really are obsessed with roaches aren’t you….. I hope you know that they have a better chance of surviving a nuclear blast than you do:)
