Drainfly (Psychoda alternates)
Adults are active at night while during the day they remain attached to walls in places where little light penetrates. They are poor flyers and only move short distances from larval development sites.
Species of urban/industrial interest frequent damp, shady places and often abound near sewage farms where larvae play an interesting role in degrading organic matter apart from being able to feed on biofilms which form on discharges; they are also able to feed on very small animals.
They are of no medical interest because they do not bite. In industrial environments they can be a source of organic contamination, so they may need to be monitored / controlled in the food industry.
Igiencontrol offers the following methods of disinfestation:
- Classical methods using chemical insecticides and development inhibitors;
- Innovative methods, through the use of techniques which envisage the use of cold gases.
