Question:
What is the difference between Carpenter Ants that eat the wood in my house and those large black ants that we see outside as they keep coming into my living room.
Answer:
They may be the same species. Carpenter ant workers are polymorphic which means they can be of differing sizes. I would need to see a specimen to accurately identify it. Carpenter ants don’t actually eat wood. They chew it up and spit it out to make cavities in which they build their nests and look after the colony. Look out for piles of frass, soft ‘sawdust’ with bits of dead ants in it. If you see this inside your home call us asap.
