Hi and welcome to our site https://pestkill.org/ I am a professional specialist in pest control. The rodent invasion problem is characteristic of all branches of the food industry, because rats and mice always go where they can live.
Synanthropic rodents are omnivores. Every year they destroy more than 33 million tons of grain, willingly eat vegetables, meat, fish and dairy products. One rat absorbs up to 20 kg of food per year, and infects with excrement 10 times more food.
