We don't often find flies such a popular topic of conversation, but given recent events, we'd like to seize the moment to share some science-based information about their status as both pests and beneficial insects.
Flies can be nuisance insects both indoors and outdoors. There are many species of flies in California with some being more problematic than others. In UC IPM's publication Pest Notes: Flies, the authors provide information about identification, habitat, damage, and management of several common flies including house flies and face flies.
You may be surprised to learn that some flies are actually beneficial insects. Many flies in the...
If you have house or office plants and have ever seen small, dark-colored insect swarming around them, your plants could have fungus gnats.
Fungus gnats are tiny flies that as adults, resemble mosquitoes. Fungus gnats don't bite people, but their presence can be annoying. Their larval stage lives in wet, overly moist potting mix, where they feed on decaying matter.
The first step to managing fungus gnats is allowing the soil in your houseplants to dry out in between watering. To read more about how to manage this pest, visit the UC IPM publication Pest Notes: Fungus Gnats.

Will all the pollinators please stand up!
Or do a fly-by like the Blue Angels or a crawl-by like babies competing in a diaper derby.
Bees--there are more than 4000 of them in North America--are the main pollinators, but don't overlook butterflies, beetles, birds, bats and moths.
Hover flies, aka flower flies or syrphid flies, belong to the family Syrphidae. Scientists estimate that worldwide, there are about 6000 described species in 200 genera. As their name implies, hover flies "hover," sort of like a helicopter preparing to...
Summer is in full gear and along with warm weather comes the abundance of some seasonal insect pests such as flies. Of the thousands of fly species, only a few are pests in and around the home, the most common one being the house fly.
Flies can carry bacteria and viruses that cause conditions such as diarrhea and food poisoning. House flies pick up disease agents while feeding on materials like feces and then deposit them onto human food after contact with or feeding on human food.
The best way to deal with house flies is to use a combination of exclusion and sanitation practices. While humans commonly find adult flies to be the most bothersome life stage, the larval stage is the best target for management efforts....
