Must-Know Information on Treatment
- All treatment methods have strengths and weaknesses, hence an array of tools and techniques are needed to control invasives in a large and complex area.
- Some treatments are appropriate in some situations while not in others.
- Special measures must be followed in protection zones such as designated Wilderness, special-status species habitat, wetlands, riparian zones, archeological and traditional use areas.
- Different methods of removing invasives require different tools and precautions. (Please visit our Advanced Treatment page for more information.)
- It is important to do research and reach out to your available resources before attempting to remove invasives on your own.

Use weevils, beetles, goats, sheep, cattle, root borers if prior researched results have been effective.
Use chemicals applied by foliar (applied by pump or electric tank and nozzle sprayer), sponge (applied by soaking a sponge in chemical and blotting cut stump), basal (applied by spraying either girdled or unaffected bark), injection (taking a large syringe and putting chemical directly into plant), or cut stump (applied by immediately applying herbicide to a cut stump).
Use techniques to physically remove invasive plants. Some examples include: brush mowers (handheld, PTO, or self-powered), chainsaws, loppers (large shears), shovels, Weed Wrench or Puller Bear ® (pulling devices), black plastic tarps (smother plants over several weeks), prescribed burning (written by a certified Burn Planner).
