At the lower part of the tubular element there are means (8) allowing an end portion (13') of the lowest poison rod (13) to be exposed for destructive animals at a certain distance from a floor (3). Screening means (9) prevent dogs, cats, etc. from getting access to the exposed end portion (13') of the poison rod. A poison preparation in the form of solid rods (13) contain poison but for an upper end portion (13"). To advantage the rods contain a mixture of poisoned so-called dry bait (typically about 2/3) and a stabilizing material or holder, preferably paraffin (typically about 1/3).
