Rats are pathogens and simply disgusting for many people. No one wants to have them in the garden, let alone in the house. With many remedies for rats that do not work, or only once, it's not easy to get rid of them. Even a rat trap is not a 100% sure thing. The animals are very capable of learning and have been caught a rat, the others avoid the trap, no matter how many times they are surrounded. If you are dealing with a single animal, the trap can be quite helpful, it will be difficult for a whole family.
One distinguishes impact and box traps. Drop traps kill the rats, usually very fast, without tormenting. Box traps are more humane, at least as long as they are checked regularly, so that the animals do not starve to death and die of thirst. It is important to place the traps on the paths of the rats. These are recognizable by signs of smudges on the walls. Rats prefer to move along walls.
Although rat traps are commercially available at relatively low prices, these are usually those that kill rats. Life traps cost a lot more, which is why many hobbyists prefer to make them themselves. These traps have the advantage that the rats are allowed to live on. They are exposed in the wilderness, as far away as possible from human habitation.
Build rat trap
You can build very simple traps with little resources, but also with slightly more materials a little more complicated. Since one needs in a rat family anyway different traps, it makes sense to try once all.
The simplest thing is to take a tall container like a metal bucket and set it up with the opening. Important are the smooth walls. The rat is not allowed to climb up on them. A bait has to be put in the bucket. Cheese does not eat rats so reliably, fruit is better, but something sweet like chocolate like the animals very much. They prefer Nutella, because they can hardly resist. To get in, access must be created. A small wooden board or thick folded cardboard are helpful. You can also build a staircase out of boxes. It is best to put some small baits on these, so to speak. Thus, the rat gets to the edge of the vessel, jumps down and is stuck.
- Larger high vessel with smooth walls so the rat can not climb out
- Conveniently, a large bucket, if possible made of metal
- Bait, preferably Nutella, alternatively fruit or chocolate
- A staircase made of cardboard boxes, a wooden board or thick cardboard
It is important that the rat gets on well with the bait, so you have to build a "ramp" again. The bottle on top can be placed in two ways, in the direction of travel, when the animal comes up the ramp, then it can just go on. It is better, however, if the rat has to jump on the bottle, so this is opposite to the direction or simply mounted transversely. As soon as the rat lands, the bottle turns and the rat falls.
- Plastic bottle with bait "stuck"
- Rod for threading
- Bucket, if possible with removable handle (two openings for the rod)
- Larger vessel, for example a pot
- Wooden stick, for example a chopstick or a pencil
- Bait, something to skewer
More complicated traps
Somewhat more elaborate is to build the rat trap out of a box. This should be a bit longer, at least twice as long as a rat. At both ends an entrance is created. In the middle of the box is divided and a grid installed. This ensures that the rat can penetrate from both sides and is then trapped. A mechanism that closes both doors would be quite complicated. In the lid of both "departments" a small hole should be drilled that allows a look inside. The bottom of the box is sawed out. It serves as a rocker to trigger the lock, which closes the exit. Store the rocker to the middle of the box.
The inputs on both sides should have a diameter of about 60 mm. They can be closed from the inside by means of a tin lid. When empty, a mechanism keeps it open. When a rat enters the interior and the installed rocker, it moves the mechanism with its weight and the tin lid falls in front of the entrance.
The mechanics are simple. The movable floor is connected at the bottom with a wave of iron wire. On one side, the shaft must look like a lever. The bottom is fitted in the box, so that the shaft is movable, otherwise the rocker can not tilt. Of course, the metal lids must tightly close the opening, so be big enough. It is beneficial that they are quite heavy, so that the rat can not press them. It is better to build a small latch as a backup, which prevents the pressing. It is important that the opening is accessible from the outside, so that the caught animal can be released at the right place.
- Crate, at least twice as long as a rat
- Grid for separation
- 2 sheet metal covers
- Wave of iron wire
- Small latch
