The answer to 'are carpenter ant dangerous' is that carpenter ants are not generally considered dangerous to humans, but they can cause significant damage to wooden structures in homes. Carpenter ants are large black or reddish-black ants that nest in wood, and they can hollow out wood to create their nests, which can weaken the structural integrity of a building over time.
While carpenter ants do not sting or bite humans, they can be a nuisance and can cause expensive damage if left untreated. Homeowners should be on the lookout for signs of carpenter ant activity, such as sawdust piles, and should consider hiring a professional pest control technician to inspect and treat the problem if necessary.
