Rats eat our food or make it so dirty that it isn't fit for people at all. That's why people often kill them by laying down poison. After a day or two, they find the poison still there. The rats haven't touched it, even though it is near the food which they eat. People think they must be clever and cunning. Some scientists have been trying to find the best way to poison rats. They have watched to see just what a rat does day and night. They have found out that rats aren't so clever. They are just very shy.
Rats usually live in holes. They run from these holes to the places where they eat and drink. They have special paths on which they travel each time. So they know their paths quite well.
If anything new, such as stone or wood, is put in the path, the rats won't go near it at first as they are too frightened. It will take them many days to get over the fear. They are also frightened to go near a place that they know, where something has been taken away. If a path goes around a rock, the rats follow the same path around the rock each time. If the rock is taken away, they will still run round the place where the rock was! They won't cross the empty place, which is now open to them, even though it would be quicker.
Rats will always keep away from anything unusual to them. That's why they won't eat poison on the first or second night. They usually won't go anywhere near it for about four days until they get used to being there. Even then they only eat a little at a time.
If people want to kill rats with poison, all they have to do is to leave it out for a few days. Once the rats have got used to it, they will eat it and die.
