The sewage system is also outdated in many places. Rats can enter houses through the smallest openings. Digital fully automatic traps are supposed to kill rodents.

Rich Switzerland, nice shop displays. Everything sparkling clean and beautifully prepared. One would never think that rats are up to mischief in this country – let alone in shops.

Rats can be found in unclean places – in the Third World, perhaps in New York or Paris, but not in Switzerland. Not even close. The Tages-Anzeiger »recently reported on a reader video that shows how rats are up to mischief at Coop Stadelhofen in the middle of Zurich.

At night, the rodents tore down egg boxes, bit open a tube of mayonnaise and lick it empty. Coop reacted immediately, sealing possible entry points for the rats, setting up traps and putting out poison baits.

Hygiene guaranteed
It gets a little queasy for the viewer to see pictures in Zurich that are otherwise only known from vacation. Finally, rodents can also transmit diseases, including Salmonella and Lyme disease. In this case, Coop spokesman Markus Eugster excludes a health hazard. Hygiene was guaranteed at all times.

According to experts, the fact that the rats chose the Coop branch near Stadelhofen has to do with the abundant food supply nearby. The train station is very busy. There are food scraps in abundance, such as discarded food scraps, bread for pigeons and ducks, or food that is washed down the toilet – which also attracts mice.
–
Garbage bags that are placed in front of the house the evening before can also be a find for the rodents. The more food available and the fewer interventions, the larger the rodent population.

Climate change accelerates rat reproduction
“In Zurich and Bern, there are currently extremely many rats and mice, it is almost degenerating,” said Thomas Iseli, exterminator at the Insekta pest control company in Brüttisellen ZH, to the newspaper. «We have seen an increase since last November. We work almost every day because of the rodents. »

Across Switzerland, in all cities, there is an increased activity of rats and mice. One possible reason for the increase is climate change: “The mild winter means that more rats, especially old and sick animals, survive,” says exterminator Simon Gross from Desinfecta in Deisswil BE.
–
In addition, rats would reproduce faster at warmer temperatures. If nothing is done, the rat population can explode. And dry summers with a lower groundwater level mean that the animals’ natural habitat becomes larger. If rain sets in, the rodents dodge the surface.

Digital traps instead of poison
In Zurich in particular, many sewer pipes are sometimes 100 years old, outdated and rotten. Rats and mice enter houses through the smallest openings. But the use of poisons is heavily regulated and restricted by the EU. Rats have also become resistant to numerous poisons.

Instead of poison bait, digital traps are now being used in many places: boxes with an electronic transmitter. The animals die from a broken neck. And for every animal caught, the box issues a message so that the population of the rat population can be tracked in real time. (KES)
