In conditions of semi-voluntary breeding of nutria, passive-action live traps made of metal mesh in the form of a prism with sides 25x25x70 cm with lifting doors are used (scheme a, b).
Passive living traps on nutria, muskrat, voles, rats, mice, purpose, device, operating principle, manufacturing, installation and tuning.
The doors of such a passive live-trap are suspended on two rings to the upper side of the frame. The height of the door is 5 cm larger than the frame, so it is tilted into the live trap at an angle of 30 degrees. Nutria is pre-fed inside a live trap with a raised door. When they need to be caught, the door is lowered. The animals, accustomed to visiting the live trap, themselves lift the door, enter the live trap and find themselves caught..
The door of this passive live-trap can be guarded with a thin cable or cord stretched from a raised door to a guard suspended from the rear wall shaft. The loop of the cord is put on this rod, it is lowered down to the floor and so that it does not turn up, its end is piled with carrot or some other bait.
The animal that has visited the live trap will take the bait, release the rod, which, under the influence of the pulling force of the cable, rises up, the loop of the cord jumps off it and releases the door, which will fall down and close the exit.
Live-traps of a passive action on a muskrat, purpose, device, principle of action, manufacturing, installation and tuning.
Hunters catch the muskrat and some other fur-bearing animals using other top-mounted passive-action live traps made of metal mesh. On a cylinder with a size of 50×25 cm, the bottom is braided with a mesh on one side, and a “baby” is woven into the bottom – a funnel cone with an inlet 10 cm in diameter (diagram c, d). This cylinder is installed in the water “baby” before leaving the hole or in the hole of the muskrat forage hut.
If you want to catch the animals alive, then a side cage is attached to the top – a mesh cage so that it rises above the water. In field conditions, when using more than a dozen peaks for transport convenience, it is recommended that they be folded using the method of assembling them using “lacing” to the bottom cage and “baby” body with a thin cable, as described in previous designs of live traps.
Passive living traps on voles and rats, purpose, device, principle of operation, manufacturing, installation and tuning.
For catching the bait of voles, water rats and other mouse-like rodents, “hunting pits” are successfully used – metal buckets and glass cylinders with a diameter of 15-20 cm and a height of up to 30 cm. Cylinders are buried in the ground to the level of a path trodden by animals or a groove specially cleared in the grass which do not miss the opportunity to take advantage of all sorts of mouse-like rodents.
For catching house rats, a cylindrical bucket is equipped with a tipping lid made of light metal or plastic, poorly balanced in a horizontal position (Scheme e). This lid is attached on the axis below the edges of the bucket by 5-7 cm, and a bait is attached to the middle. At the bottom of the cylinder, a third of the brick is laid and so much is poured
water so that he barely protrudes.
Gangways are attached to the bucket from the boards, on which paths are spread with bait. On them, the rats go up and, finding the bait on the lid, jump to it and fall into a bucket. Caught rats raise fuss in a bucket because of the place on the brick and thereby attract the remaining rats.
Live-traps of passive action on ermine and affection, purpose, device, principle of operation, manufacturing, installation and tuning.
For catching by living an ermine and affection, a “hunting pit” is sometimes used – an ice-cold. In winter, water is frozen in a cylindrical bucket to a thickness of 3-4 cm. Then, in the upper part, a round hole is punched with a diameter of 4-5 cm, all non-frozen water is poured through it. The bucket is brought into a warm room and after 15-20 minutes an ice cylinder is thrown out of it, into which a little straw with grain is placed and a live mouse is planted.
In the ermine and weasel habitats, a cylinder with a bait is buried in the snow, flush with its surface. The work of this live-trap is based on the fact that an ermine that has climbed into it cannot get out (Scheme e).
Passive live traps in the form of a glass for catching house mice.
An ordinary tea glass can very successfully catch house mice. On a flat floor surface or on a special board, a glass is guarded by the following method. Inside, on a side wall, 2-3 cm from the bottom, apply a smear of butter or some kind of fat. On this side, at an angle of 60 degrees, the glass is placed on a plank or floor and on the opposite side is propped up with a match shortened to 3 cm.
When installing a match, they find an equilibrium point near the glass, at which it is barely held on it in an elevated position (scheme g). From a glass with an oil finger, two or three directions of the strip are carried out. On them, the mouse is oriented and climbs under the glass. Reaching for a smear of fat, it rises to the hind legs, the front rests on the glass and puts it out of balance. The match falls out from under the glass, and the animal covers the glass (diagram h).
