The BPCA catalogue of the most common public health and nuisance pests has been created to enable members of the public to make an educated choice when considering pest control.
The insect normally referred to as a gnat is actually a small mosquito - correct name: Culex pipiens. It is common in gardens on warm evenings. Another species, the true Window Gnat, is a slow-flying insect about 8mm long with wings more rounded than those of the mosquito.
The wings are strongly veined with dark tips. Eggs of the Window Gnat are laid on rotting fruit or vegetables or other moist food and the larvae may contaminate home-made wines or honeycombs.
The Window Gnat tends to stay on windows and is therefore easily killed by a good swat, or by spraying with a fly killer aerosol.
For a heavy Gnat infestation, we would recommend you contact professional pest control company, preferably a member of the BPCA to administer a professional treatment to solve the problem. A trained professional will have the technical knowledge and access to a range of professional use products and equipment which are not available to the public.
