Little Fire Ant Treatment

[terracore]

For people who are using the Tango gel ant bait recipe from the Hawaii ant lab: I've tried using the Zep sprayer they recommended but I'm not having any luck with them. The first one worked for one application, I ran some water through afterwards to clean it out, and then it failed half way through the next application. The second Zep sprayer died halfway through the first application. So far, the Zep sprayers have been duds. What do you use? What are your recommendations?

thanks
