Signs You May Have Rats

Rats often remain hidden, especially during the early stages of an infestation. Signs that may indicate rodent activity include:

Seeing one of these signs does not always tell you the full extent of the problem. A professional inspection can help identify where rats are active and how they may be entering the property.

Why Rat Problems Need Attention

Rats are more than an inconvenience. Once inside a home or commercial building, they can damage property and contaminate areas where food is stored or prepared.

Rodent activity may result in:

  • Gnawed electrical wiring
  • Damaged insulation and stored materials
  • Contaminated food or food-storage areas
  • Droppings and urine in attics, garages, and other spaces
  • Damage around entry points
  • Continued activity as rodents find food, water, and shelter

The longer entry points and favorable conditions remain, the more difficult a rodent problem may become to control.

Reducing access to food, water, shelter, and entry points can make a property less attractive to rats. Helpful steps include:

Even well-maintained properties can experience rodent problems. If rats have already entered a structure, an inspection can help determine where they are active and what should be done next.

Common Rats in the California Bay Area

Two rat species commonly encountered around Bay Area properties are Norway rats and roof rats. Knowing which type of rat is present can help determine where technicians should inspect and which control methods may be appropriate.

How do I tell If I have Norway Rats?

Norway rats tend to spend more time near ground level and may be found around foundations, crawl spaces, garages, landscaping, and other protected areas.

How do I tell If I have Roof Rats?

Roof rats are strong climbers and are often associated with attics, rooflines, trees, vines, fences, and utility lines that provide access to elevated areas of a structure.

Our Rat Pest Control Process

Effective rat control starts by understanding where rodents are active and how they are getting into the property.
