Is Bagged Mulch Treated for Termites?

The answer to both questions is, "no." Landscape mulches contribute to a stable moist environment that is good for our trees and shrubs, and unfortunately, also good for termites and other insects.

Can termites live in bagged mulch?

It's not impossible to find termites in a bag of mulch, but it's not likely they would survive for long or even be alive once the bag is opened. A termite has a slim chance of surviving the chipping process that is used to create bagged mulch.

What is the best mulch to prevent termites?

Redwood and cypress contain resins that make the wood less attractive to termites. Cedar mulch contains thujone, which is a chemical that deters insects. When it comes to termite-resistant mulch, melaleuca wood might be the best choice, as the insects will actively avoid eating it.
