Rodents and mammals
The most harmful rodents to humans are mice and rats. Mice and rats are disease vectors and sources of allergens. They eat and contaminate food, damage property by soiling or gnawing it, sometimes causing breakdowns, water damage or fires. They sometimes carry fleas, mites or ticks. If you suspect their presence, you must act quickly by inspecting in depth to identify which species is involved and determine the extent of the problem.
