Spread of Influenza Viruses
Multiple studies have demonstrated that all these household pests are cold-flu virus carriers. When outdoor pests including cockroaches, rodents, birds, and bugs invade your home, your likelihood of spreading cold-flu viruses increases. Such diseases are transmitted from one person to another or between animals living in close proximity.
The Spread of Infections
Household pests are indeed a common source of household infections. The presence of various microorganisms, allergens, and large amounts of bacteria on these pests facilitates the spread of infections. Rats, cockroaches, ticks, and fleas are known carriers of salmonella, E. coli, and Lyme disease.
