It is disclosed a device for controlling and/or euthanizing vermin or pests for preventing such vermin or pests from entering into a geographical area or into a building, wherein the device comprises at least one completely or partially unisulated electrically conducting wire or conductor connected to an electrical current source, providing controlled electrical pulses to said conductor or wire in the form of pulses or pulse trains. The device may be used in a method for controlling the access of pests/vermin to a geographical location, building or property wherein the electrically conducting wire(s) lead(s) an electrical current with an amperage of not less than 0.0001 A. The device and method is particularly suited for removing/controlling pests/vermin on land of the type rodents (mice, rats, rabbits, etc.)； insects (cockroaches, beetles, ants, termites, mosquitoes,moths, wasps, scorpions, grasshoppers, etc.)； arachnoids ((spiders), multi-jointed, animals (centipedes), mollusks/nematodes (snails)； birds (pigeons, gulls, crows, etc.)； reptiles (snakes, geckos, etc.)； other pests such as pine marten, weasel, raccoon, rabbits, gophers, moles, raccoons, etc. as well as animals that can attack humans such as hyenas, tigers, bears, wolves, wild boar, etc. as well as sea organisms such as sharks, jellyfish, carbuncles, starfish, mollusks, etc. Areas of particular relevance is in sewers for removing rats and harbors or boats for removing organisms that interfere with the smoothness of hulls as well s preventing salmon lice in plants raising salmonids such as salmon and rainbow trout.L'invention concerne un dispositif pour euthanasier et/ou lutter contre des animaux indésirables ou des nuisibles pour empêcher de tels animaux indésirables ou nuisibles d'entrer dans une zone géographique ou dans un bâtiment, le dispositif comprenant au moins un conducteur ou fil électroconducteur entièrement ou partiellement isolé relié à une source de courant électrique, fournissant des imp
