Dethlac Insect Lacquer - 250ml
The Dethlac Insect Lacquer by STV is a tried and tested insecticide that is extremely effective against ants, woodlice, cockroaches and other crawling insects. This insecticide is to be sprayed onto non-absorbent surfaces where it then dries into a hard clear film that is then fatal for the insects that step over it. A great choice for those with less time to play with, this lacquer continues to work for months indoors and outside, even after rain and washing of surfaces.
Features:
- Kills ants, woodlice, cockroaches and other crawling insects
- Can be applied to any firm non-absorbent surfaces
- Dries to a hard clear film which kills insects within a few hours of coming into contact with treated surfaces which remains fully effective for months, even when it rains or if the surface is washed with detergents
Dimensions:
- 250ml
