OP-9: Integrated Pest Management

The grounds of UNLV comprise 342 acres. Both the landscaped areas and interior spaces are maintained in accordance with IPM practices.

Action thresholds are set for different areas of campus and vary with location. Larger populations of insects and weeds are tolerated on the intramural fields which are not viewed up close and only have turf. The same relative populations in the Wynn Rose Garden are completely unacceptable as this is in a central area of campus and is used for events and photos, and is highly visited by the campus and outside community.

The campus is monitored daily by zone crews. When pest populations are detected, they are discovered early therefore control is more easily achieved. Populations may be monitored over a period of days to determine if action is necessary. For example, bees are active in the spring and can be found feeding in various locations on campus. Sometimes they congregate in great numbers. If they are in an area of campus which is routinely travelled by people, action is taken to remove or control them if they have not moved on within a couple of days. If removal is necessary, UNLV has access to a beekeeper who is willing to remove the bee hives to another location.

Preventive measures are used to reduce or eliminate pest populations. Weeds are removed prior to seed formation. Plants and turf are fertilized and maintained properly to keep them healthy and less susceptible to insects and disease. In the case of turf, healthy, dense growth prevents weed invasions. Bird spikes, scent cannons, and sound systems are used in attempt to encourage pigeons to nest elsewhere.

Native plants are increasingly being used in the landscapes. In addition to conserving the precious resource of water, they are better adapted to the environment and generally require less fertilization and pest control.

When chemical control is necessary, products are selected which are least harmful to the environment, wildlife, and humans. Small insect populations are sprayed with a stream of water or hand removed when possible. Insecticidal soaps are used if physical control is not possible, and are effective on some fungal disease causing organisms. When this is not enough, chemicals are chosen which are effective and relatively safe for the environment. Early detection leads to less chemical being sprayed and fewer applications. No restricted use chemicals are used on the grounds at UNLV.

Personnel are trained on proper use of pesticides. Most of the grounds crew and all of the supervisors are Certified Pesticide Applicators. The certification course teaches selection, safe application and laws regarding pesticide application. Integrated Pest Management principles are included. Continuing education credits are required for maintenance of this certification.
