Query: Stuff the pros use

I had an exterminator come over to help with our ant problem in the house and he told us all about why to not use ant traps and how to use a gel (which he says you can't buy) to get the poison to the nest to kill all of them. He showed us how/where to put the gel, so after we ran out of what he gave us, we bought this stuff and it works great. We've since had a small ant problem and used this stuff, and they were gone in a day or two.
