Dethlac is a unique lacquer that kills woodlice, ants, cockroaches and other crawling insects.
Once sprayed, Dethlac dries to a hard clear film, which remains fully effective for months, even when it rains or if the surface is washed with detergents.
Dethlac can be used indoors and outdoors and may be applied on any firm non-absorbent surface, ie doors, window frames (not upvc), skirting boards, shelves, concrete & patios etc.
