Factors Contributing to Bee Decline
Bees provide an important ecosystem service by contributing to the pollination of crop and wild plant species. The nonnative honey bee (Apis mellifera) is often recognized as the most important of the bee pollinators; however, the roughly 4,000 native Nor
Gardening and Landscaping Practices for Nesting Native Bees
Utah is home to about 1,000 named species of native bees, with several hundred species living in any one valley and adjacent montane habitats. Urbanization takes its toll on native bees, but many species can persist with a little help from gardeners and
Making and Managing Wild Bee Hotels
Bee hotels (also called “bee boxes” and “bee blocks”) are popular additions to Utah backyards and commercial agriculture alike, adding nesting habitat to aid local pollination efforts and address native pollinator declines. Common hotel residents inc
Aphid Natural Enemies and Biological Control
Aphids are prey to many predatory insects, spiders, and parasitoids. Healthy predatory populations keep aphid populations low, which can reduce or eliminate the need for chemical controls.
Reducing Pesticide Poisoning of Bees
Choose insecticides that are non hazardous to bees whenever possible. The more hazardous insecticide active ingredients include many of the organophosphates and the carbamates, and some of the synthetic pyrethroids and neonicotinoids.
Beneficial Insects: Syrphid Flies
Syrphid are beneficial predators of small soft-bodied pests like aphids, thrips, and scale insects. Adults may feed on pollen and nectar, pollinating plants in the process.
Beneficial Insects: Big-Eyed Bugs

Gardening for Native Bees in Utah and Beyond
About 1,100 species of native bees reside in Utah. Some wild bees are superb pollinators of Utah's tree fruits, raspberries, squashes, melons and cucumbers. Few of our native bees have much venom or any inclination to sting.
Beneficial Predatory Mites
Predatory mites feed on all life stages of many small arthropods and target pest spider mites. Most predatory mite species do best in humid conditions and controlled environments such as greenhouses and high tunnels.
