Insects in the Garden

The following list of common insects in Wyoming homes is based on citizen's identification requests to the University of Wyoming's Extension Entomology faculty.

Beneficial Insects

These insects won't harm you; in fact, they might be your best friend in pest defense. 

Minor Garden Pest Insects

These insects are not a major problem in low numbers. Make note of their numbers. If their numbers begin to suddenly increase, try modifying your landscaping strategies before using chemical treatments.


Major Garden Pest Insects

These insects are potentially major economic pests in gardens and yards. Monitor their numbers and your plant health. An increase in occurrence merits management for a healthy garden or yard. Before using chemical treatments, try some basic IPM strategies first. Discover where they come from, how to physically modify the environment, how to change your landscaping strategies, and, finally, limit chemical treatments to the area of concern. In major outbreaks, effective pest management may require community or neighborhood cooperation.
