I've used these for years, and they work every time.
Brad's Deals Editor Marisa,
This 6-Count Box of Terro Ant Baits drops from $6.79 to $4.58 at Amazon. This is the lowest price we've seen since April, and it's the best deal you can get right now on a six-pack. These ant baits can be used indoors or outside. Prime members get free shipping. Non-members get free shipping at $25, otherwise it adds $5.99. Sales tax is charged in most states.
