Crane fly larvae range in size from 5 mm in the first instar up to 4 cm in the final instar before pupation. Crane flies like moist, vegetative, outdoor habitats, and are usually only seen around a home on external walls and window screens. They lay their eggs in moist soil and when the larvae emerge, they feed on the roots of grasses, decaying organic matter, decaying wood, vegetation, and turf.
Some larvae also feed on small aquatic insects, invertebrates, and any decaying plant life found near the surface of streams. Crane flies do not bite or sting humans, livestock, or pets, but can become a major pest to turf, pasture grass, golf courses, and field crops. This is due to their voracious larvae, which can leave grass yellow and thinning — and whole patches entirely bare.
Hatched larvae may cause damage to plant roots in large concentrations and attract more pests, like skunks, birds, and raccoons, who may try to dig up the ground in order to feed on them. A female crane fly lays up to eggs in the ground, all of which hatch into hungry larvae within two weeks. To eliminate a crane fly infestation, you need to focus on their larvae. Registered insecticides can be effective, if used in late fall when eggs are laid and larvae are active.
To be sure your crane fly infestation is over, a professional pest control service is essential. Several things can be done to prevent crane fly infestations; maintaining a healthy and vibrant turf or lawn will make it less susceptible to the flies. Because crane flies lay eggs in wet soil and the eggs are vulnerable to desiccation, improving drainage to allow proper soil drying and aeration will prevent egg laying.
If the eggs are already laid, they will still dry out. There are several registered products available in Canada that can applied as preventive treatment, but always remember to read and follow label instructions of the product. Insect-eating nematodes such as Steinernema species are also registered and available for use as biological control; they feed on the larvae.

Q: Most of the time, the crane flies we see around the house appear to be doing absolutely nothing. Why is that? Imagine if we stopped eating food at age 18, and had to get by our entire adult lives on the food we ate as children. Similarly, crane flies have to conserve their limited energy resources and just hang out doing nothing quite a lot.
But when they see potential mates or good places to lay their eggs after mating, then they'll spring into action and fly around. A: In Tucson, we're likely just seeing one or two species of crane flies that can tolerate our hot and harsh desert soils as larvae. But if you go out to Sabino Canyon, or any of the other streams in the local mountain ranges, you may find as many as 15 to 30 different species of crane flies living in a single stream pool.
They are really important parts of our local ecosystems and contribute greatly to our region's famous biodiversity, both urban and wild.
