Tree-of-heaven is especially successful at establishing around riparian areas, and changes streambed ecology by forming dense thickets that crowd out native plants, alter physical habitat, and produce chemicals that prevent other plants from establishing nearby.

Well-established tree-of-heaven stands are only eliminated through repeated monitoring and control efforts. Initial treatments often only reduce the root systems, making follow-up measures necessary. Persistence is the key to success.

Uses: Tree of Heaven can be used for cabinetry, turned objects, and paper (pulpwood). Availability: In many locations Tree of Heaven is considered an invasive species. The wood is not listed in the CITES Appendices or on the IUCN Red List.

Then there's the sugary, sticky liquid they secrete called honeydew, attracting bees and wasps—the honeydew now covered with black mold.

Use glyphosate (Roundup) plus triclopyr (Vastlan) as a foliar application (meaning directly to the leaves) where tree height and distribution allow effective coverage without unacceptable contact with desirable plants nearby. Apply treatment in mid- to late growing season, which is typically late July to August.
