Under these conditions, and more specifically in warm regions such as Alicante, Valencia and Murcia, they not only present a danger because they are carriers of infectious diseases: increasingly, insects and rodents are carriers of microorganisms that they themselves transport. Many pests, in their search for food and water, move through garbage (the ideal breeding ground for a wide variety of unwanted microorganisms). But when they get close to the kitchen of our home or restaurant, a food warehouse or a clinic, they spread pathogens (bacteria, viruses, fungi and other infectious organisms). This is why pests, when they coexist among us, present a great health risk.
