Acrobat ants frequently nest inside decaying wood. Form single file trails. Often leave behind small sawdust piles that resemble those of carpenter ants.
If bitten, acrobat ants will produce a mild sting. May move into attics to incubate eggs and brood. Will tunnel into water-damaged wood.
Granular bait around the perimeter of the structure work well to treat acrobat ants. Perimeter spray with a non-repellent product.
