thanks a lot to all of you who help me.. im just new here in the site i dont know where to post this topic... i wanted this very badly because its sure will help me to combat ants... by the way it will also help you all by making a syrup out of this boric acid powder.. you just need to mix 1 tbsp of boric acid to 3 tbsp sugar them melt it by boiling with a small amount of water, then let it cool after that just pour the syrup near the ant colony or pathway... the ants will eat /drink it then take it to the queen ants where the queen ant will eat/drink it also then after they ingested it it will cause constipation to the ants then after that dehydration that will kill them all in about 2 to 3 days... kep it away from pets and kids... thanks again for the help....
