Silver maple ant infestation #879594

Asked July 31, 2024, 1:30 PM EDT

Hello, I have a large, 50+ year old, silver maple that appears overall healthy but seems to be infested with carpenter ants. We get small brown wood shavings on the deck every morning this summer. Is this going to be damaging the tree in any way? If we should have it inspected, treated, how would we find a reputable firm to do this?

Hello,

Carpenter ants in trees, such as your silver maple, are not directly harmful to the tree’s health. They do not feed on wood but create galleries with rotting wood to build their nests. More information at these links:

The presence of carpenter ants and wood shavings (which look like coarse sawdust) can indicate a moisture and decay problem within the tree, but this does not necessarily mean the tree is in decline. Nests can often go unnoticed for years in healthy trees since the ants are tunneling in dead tissue and not disrupting the flow of water and nutrients.

However, it’s still a good idea to have the tree inspected to assess the extent of the decay and to ensure the structural integrity of the tree is not compromised. More information at this link:

To find a reputable tree service firm, you can:

Check the phone directory’s Yellow Pages or do an Internet search for “Tree Service” in your area for a listing of businesses that do tree work.

Look for companies with association memberships, licenses, and insurance information. AND THAT HAVE A CERTIFIED ARBORIST!

Ask for proof of certification by professional organizations such as the International Society of Arboriculture.

Request certificates of insurance, including liability for personal and property damage and workers’ compensation.

Ask for local references and, if possible, talk with former clients to gauge their experience and satisfaction with the service provided.

Remember, it's important to take your time and not rush into a decision. Ensure you understand what work is to be done and the cost, and don’t pay in full until the work is finished.

You can consult a local certified arborist for a more detailed onsite assessment and personalized advice. The certified arborist is more than likely connected to a tree service company! To find a certified arborist in your Zip Code, go to this link:

It’s also advised not to treat tree wounds with wound dressings, as such treatments are unnecessary and will not eliminate nor prevent decay or carpenter ant activity. More information at this link:

I hope this helps!
