Castaic FAQ
Can I plant tree-of-heaven in my yard?
Technically not banned countywide, but strongly discouraged. Cal-IPC lists it as high invasive, the spotted lanternfly threat is real, and you may receive a county nuisance abatement order if it spreads to neighboring property.
How do I remove tree-of-heaven without it growing back?
Cutting alone causes aggressive resprouting. Use cut-stump herbicide application within 30 minutes of cutting, basal bark spray, or foliar treatment of suckers. Consult the Agricultural Commissioner for treatment guidance.
Los Angeles FAQ
Do I need a permit to cut down a tree-of-heaven on my property?
No. Ailanthus altissima is not a protected species under LAMC §46.00 et seq. You may remove it without a permit. Parkway specimens can also be removed under LAMC §17.05 weed authority.
How do I report a suspected spotted lanternfly?
Contact the LA County Agricultural Commissioner at (626) 575-5471 or report through CDFA's Pest Hotline (1-800-491-1899). Photograph the insect and note nearby Ailanthus trees, the primary host.
