San Diego FAQ
Do I have to remove tree-of-heaven from my yard?
Generally no for residential properties outside conservation areas. Within MHPA or restoration easement parcels removal is required, and homeowners are encouraged to remove and report sightings to the county Ag Commissioner.
Why is ailanthus a concern?
It is the preferred host of spotted lanternfly, a destructive vineyard and orchard pest now in 18 states. California is preparing for arrival, and reducing ailanthus reduces establishment risk for the lanternfly invasion.
