– If they gnaw the power lines, they can cause fires, then they will come too close to them, says Joakim Olsson.
Rats like to be close to people
One of the reasons for the increase may be different buildings, which means that the rats have to move, says Joakim Olsson. Another is the food.
– They like to be close to us people and leave us left food residues it becomes like a sandwich table for them. Last year’s summer was also long, right into September you could have a picnic and the rats might get some extra food and another litter, he says.
