The most economical and safest way to manage invasive species is by prevention. Early detection and rapid response of invasive species is much more effective than trying to control a widespread infestation.
If eradication is not possible, the invasive species may be subject to control and management efforts. There are various methods used for the control/eradication/management of invasive species:
- Biological control is the intentional manipulation of natural enemies by humans for the purpose of controlling pests reducing the population using prey targeting the invasive species. Includes the use of animals, fungi, or diseases typically from the targeted species home range to control invasive populations.
- Chemical control includes the use of pesticides, herbicides, fungicides, and insecticides.
- Cultural control includes manipulation of habits to increase mortality of invasives or reduce it's its rate of damage (selection of pest-resistant crops, winter cover crops, changing planting dates). Also includes measures aimed at changing human behavior to address the issue of spreading invasives -- using opportunities to educate people about practices to increase awareness to prevent the spread of invasives (signage, public awareness campaigns).
- Mechanical control techniques include mowing, hoeing, tilling, girdling, chopping, and constructing barriers using tools or machines.
- Physical (or manual) control includes activities such as hand-pulling, digging, flooding, mulching, manual destruction or removal of nests, egg masses, or other life stages; generally includes the destruction of invasive species by hand.
- Prescribed burning includes the use of fire as a control technique.
You can also use a combination of control methods for an integrated approach using Integrated Pest Management (IPM).
