Tree Busters is a locally owned and operated business in Denver, Colorado, specializing in the identification and removal of Tree of Heaven (Ailanthus altissima). This invasive tree species is a fast-growing nuisance that threatens native ecosystems, damages infrastructure, and invites pests like the spotted lanternfly. Let us help you reclaim your yard or land from this invasive threat.
Note: Our specialty is the treatment that kills Tree of Heaven at the root so it won't come back. Physical removal of the dead tree can be coordinated separately after the treatment period.
We proudly serve Denver and surrounding Colorado cities:
Tree of Heaven (Ailanthus altissima) is an invasive species native to China. It spreads aggressively through root suckers and seeds, displacing native plants and damaging structures with its extensive root system.
This tree damages foundations, sidewalks, pipes, and kills surrounding plant life by releasing toxins. It also attracts spotted lanternflies, a serious pest.
We drill into each tree and inject microdoses of a vascular disruptor directly into multiple sites. Because the method is so precise, there's no overspray or cross-contamination, and it minimizes the stress response that causes Tree of Heaven to resprout. The compound works through the tree's system over 30–45 days to fully shut down the root system. Simply cutting the tree down does not work — it only triggers aggressive regrowth — which is why treating it at the root first is essential. Physical removal of the dead tree can then be coordinated separately.

Tree of Heaven (Ailanthus altissima) may sound poetic, but it’s one of the most destructive and fast-spreading invasive species in the United States — and Denver is no exception. If you’ve noticed a rapidly growing tree with smooth bark, foul-smelling leaves, and long compound leaflets on your property, you may be hosting a silent invader.
Tree of Heaven is not just another weed. It outcompetes native plants, poisons the soil with allelopathic chemicals, and aggressively spreads by seed and root suckers. Once it establishes, it forms dense thickets that kill off biodiversity and choke out native trees and shrubs.
This tree’s root system is strong enough to break through sidewalks, sewer lines, retaining walls, foundations, and driveways. Ignoring it means paying far more later in structural repairs and emergency removal. Its unchecked growth can even devalue your property.
Tree of Heaven is the preferred host of the invasive Spotted Lanternfly, a highly destructive pest that devastates agricultural crops and ornamental trees. If Tree of Heaven is present, it's only a matter of time before these pests show up too.
Cutting down a Tree of Heaven without professional treatment will only make things worse. The tree responds by rapidly producing root suckers — potentially creating dozens more trees within weeks. Proper removal requires a strategic combination of physical removal and systemic herbicide treatment.
At Tree Busters, we’ve dealt with thousands of Tree of Heaven infestations across the Denver metro area. Our expert team can identify, assess, and treat this dangerous invader at the root — so that once it's dead, it stays dead and won't resprout.
Don't wait. If you see signs of Tree of Heaven, contact us immediately before the damage spreads. Your property, your plants, and your neighborhood will thank you.
