I only had patience for a minute or so of the video. I do hate fireants. I will likely do some killing now when it is cold. Poison the mound during a cold snap and it is harder for them to flee when I dump fluids on the mount. They can go down 4 ft in ground.
He posted a followup to this a few days ago - the Flex Seal mound was completely dead. Matt's a good guy, very goofy and loves to mess around. I enjoy his stuff from time to time.
I just ordered some generic Talstar and think I got a good price for 25 lbs of it from Do It Yourself Pest Control. They take paypal that does give some protection.
