What does it mean when house ants actively seek water?
These are probably sugar ants and they actively seek water and sugars to survive. They come inside to help survive winter weather, these ants will feed on proteins and greasy or oily foods as well. A bait containing sugars or sugar liquids will provide the best results. A homemade bait containing 2 teaspoons boric acid, 1/4 cup hot water and 1 cup of corn syrup will do very nicely. Place small amounts of the bait in bottle or jar lids and then place these containers near ant trails for the best results. Keep the bait moist and it will remain attractive to the ants.
