The tool you need for the outdoor job

Applying Talak around the entire house perimeter requires a sprayer. You could buy a fancy battery-powered one, but the Chapin 20004 is the classic choice — and with 79,451 reviews at 4.4 stars, I'm not the only one who thinks so.

How it works

Pour in the Talak + water mixture, screw on the pump handle, and pump it up like a bicycle tire. The pressure builds in the tank, and when you pull the trigger, a fine mist comes out. One round of pumping gives you enough pressure to spray at least a third of the tank's contents before you need to pump again.

The spray pattern is a nice, even mist — perfect for creating the three-foot perimeter band I needed around the house.

The bottom line

If you're setting up an outdoor Talak perimeter, you need a sprayer. The Chapin 20004 is cheap, proven, and works perfectly. Combined with Terro bait stations indoors and diatomaceous earth at entry points, you've got a complete ant defense system for around $65 total.
