"TERRO" Ant Killer The liquid ant killer contains BORAX.
Place some waterproof plastic lids on the ground around the power cord. Place several big drops of this liquid where the ants can "smell" this liquid. They will drink it up and carry it to the nest, feed it to the queen and the workers. Kills them dead. I may take several days to see the evidence of them not returning to forage away from the boat.
Comes in 1.0 FL. OZ. plastic bottle.
