Colorado Integrated Pest Management

IPM Mission and Goals

Our goal is to develop recommendations for sustainable pest management and increase adoption of Integrated Pest Management to suppress adverse impacts of pests associated with crops, vegetables, urban landscapes, and gardens.

We seek to address key pest challenges in Colorado while protecting human, environment and pollinator health/ safety.

Outcomes of our work will include increased knowledge and adoption of IPM tools, enhanced coordination, and responsiveness of IPM research, and increased availability of safe, affordable, and high-quality crops to consumers.  

Search For Pests By Category

Our new site allows you to easily search for pests by category. Find your pest based where your pest is affecting your plants and crops. We have also included a section on beneficial insects and pollinators to enhance natural pest management.

Agricultural Pests

field crops

Important agronomic commodities in Colorado such as wheat, corn, and alfalfa are host to diverse pests that limit crop production. Here you will find descriptions of these pests and effective management strategies.

Tree and Shrub Pests


Trees, shrubs, and ornamental plants make up our urban, community, and home landscapes. There are a number of important invasive and native pests that threaten these landscapes.   

Fruiting Tree and Shrub Pests

Apple trees
Fruit trees grown in Colorado include peaches, apples, apricots, plums, and pears. Pests reduce fruit yields by feeding on the fruit, and injuring different parts of the tree such as leaves or bark.

Turfgrass Pests

There are many different insects associated with turfgrass in Colorado, with a few commonly causing damage, often larvae of beetles, weevils, and moths. IPM in turf ecosystems usually requires attention to cultural practices and protection of pollinators.  

Household Pests

Arthropods of concern to community members are often those than invade homes, buildings, and yards or cause some sort of nuisance. These include ants, grasshoppers, bees and wasps, spiders, and many others.  

Industrial Hemp Pests

Hemp is a highly regulated plant with applications in medicine, clothing, and more. Learning to identify and manage pest infestations within the context of IPM can help prevent hemp yield and quality losses.

For a more complete listing of insects, please browse the Hemp Insects Factsheets compiled by Professor Emeritus, Dr. Whitney Cranshaw.

Specialty and Alternative Crop Pests

Specialty and alternative crops include vegetables, industrial hemp, and landscape plants. These diverse systems with different production approaches have unique pest challenges.  

Beneficial Insects
