Rats are one of the most annoying, omnipresent and destructive among home pests and pose real challenges to outwit them. Aggressive methods like killing and trapping are neither pro-user nor pro-planet and rats continue to invade and gnaw at everything on their path. Your dead cars and bikes, non-working appliances, electrical short circuits, data centre breakdowns are often the work of this furry fiend. The bitteR solution is based on the rodent behaviour of gnawing, by spray coating things with an extreme, active bitterant that ‘shocks’ the rat while chewing, preventing it from coming back.
