Termites or carpenter ant on deck?

Hi all,

We recently bought a house and notice there’s constantly wood particles that come out from inside the wood on our deck. The deck is around 30 yrs old, any tips on how to stop and fix this issue?


Is this termites or carpenter ant? Thank you in advance

Carpenter ants leave finer wood dust and neater clumps but it could have swelled with moisture and rain. There are other boring beetles that could be the culprit as well. If you live in Southern Ontario, carpenter ants have been a huge problem the last few years. I blast around my house, yard and in my basement, some crawling insect spray. Either that or I have spiders, ants and centipedes all over the place. And yes, I live in the city. If it's carpenter ants there will be a main nest somewhere... I found one in a tree stump at the back of my lot and went medieval on them with the sprayer.

Even if you replace the boards you'll have to deal with whatever boring insect you have, beforehand.

Just a wild guess, but it could also be carpenter bees. We've had a few of those around our house. Had to kill them one by one and then fill in the holes to make sure the young ones didn't have a chance to develop.

Do you see any ants activity? I would remove the board and inspect.
30 years old deck… maybe time for replacement

Carpenter ants are common, but one thing to realize is that they chew through rotting wood, not wood in good condition. If you see carpenter ant damage, it's a visual indication that you have rotting wood in your deck that needs replacing. As for getting rid of carpenter ants, diatomaceous earth is the best - it sticks to them like a coating of sharp micro-glass-shards and they hate it, but it's non-toxic.
