The objective is to deter crane flies from inhabiting or frequenting a particular area. This process involves utilizing methods or substances that discourage these insects, such as environmental modifications or the application of specific treatments. For example, maintaining a well-drained lawn can naturally make the environment less appealing to crane flies, as their larvae thrive in moist conditions.
Controlling these insects is important due to the potential damage their larvae can inflict on lawns and other vegetation. While adult crane flies are generally harmless, their offspring, often called leatherjackets, feed on roots and grass, leading to unsightly patches and potentially significant damage to turf. Historically, various strategies have been employed, ranging from simple preventative measures to more intensive pest control applications, depending on the severity of the infestation.
