My wife no longer holds my gewachel from wasps attacks, I can not stand the critters anyway. Price and reszessionen were good, therefore ordered unceremoniously. Meanwhile, 2 pieces in the summer and autumn use much (2 kept as a spare). Wasps (and partly other insect cornered animal) dies since good and reliable - death by electric shock. Stinks a little, but works well. It had to rise to no wasp addition, the critters die immediately. Be careful when touching, with slender fingers can touch with careless touch the grill surface before between guard the electric grid - are Kuhdrahtähnlichen shock, more frightening than dangerous. China optical mass production, but not a cheap plastic stench. All in all, a true blessing.
