De Schotten zijn er zelf ook niet blij mee: volgens schattingen uit 2008 kosten midges de Schotse toeristische industrie jaarlijks zo’n 350 miljoen euro aan gederfde inkomsten.

No flies on me! Management of non-biting aquatic midges. The use of insecticides against adults should be expected to achieve temporary control during heavy emergence periods, because treated areas are rapidly repopulated by midges flying in from outside the treatment zone.

Exposing bottom muds by draining ponds and lakes during winter months will kill over wintering midge larvae, reducing the size of the adult population emerging in the following spring. Densities of over 4,000 larvae/square feet often occur on the bottoms of nutrient rich bodies of water (sometimes an indication of pollution due to excess nutrients).

Revised: June 30, 2019. Because midge larvae are typically found in the sediment and lower strata (levels) of the water, pellet formulations Bti and S-methoprene provide the best results because they sink quickly to the bottom and release the larva-killing protein into the midge feeding zone (Gray et al. The adults are weak flyers and may fly or be blown ashore where they congregate on vegetation, under porch alcoves in carports and on walls of homes and other buildings (, Like other flies, chironomid midges have a four-stage life cycle (, During the summer, the entire life cycle from egg to adult can be completed in 2 to 3 weeks. Where the diversity of predaceous animals is high, the density of midge larvae is usually held below nuisance population levels. Lighting Modification.
