"The best in the world." That's a bold statement, but I've been dealing with ants in my kitchen for many years. I keep my kitchen clean, but if I fail to wash a knife I used for chicken, the ants swarm to it. These bait packets are the best way to eradicate ants. They take the bait back to the colony where the poison kills the queen and other ants. And I should mention the ants that invade my kitchen are protein ants. They love my roast chicken, especially chicken breast meat. Some ants seek sugar rather than protein, so a variation of these packets — such as mixing some of the poison with honey or jelly — might work better for sugar ants.
