Rodent Facts

  • Activity: Mostly nocturnal
  • Type: Mammals
  • Breeding: Too often – treat the problem NOW!

Advanced Wildlife Removal deals with a variety of rodents year round. Here in Southern California, we have two common rats: the Norway Rat and the Roof Rat.

Norway Rats

The Norway rat, Rattus norvegicus, is also referred to as the:

  • Brown rat
  • Sewer rat
  • Hanover rat
  • Norwegian rat
  • Wharf rat
  • Common rat

Norway rats usually have brown fur with gray or white bellies, and they are the largest rats in town. They can be about 9 1/2 inches long with stocky bodies, small ears and blunt noses. Norway rats are not good climbers; so, you will find them near ground level in your properties – in wood piles, trash heaps, crawl spaces, garages, basements, any room on the first floor of your home.

Norway rats are Omnivores. They eat almost anything including fruits, vegetables. Wild Norway rats have been documented to catch small fish and animals.

Female Norway rats can have up to 6 litters per year with 20 or more young successfully grown.

Roof Rats

Roof rats, Rattus rattus, are also known as “Black rats.” They have black fur, long tails and pointed noses. They earned their names by being excellent climbers! So, expect to find roof rats living on the upper levels of your properties and yards – in attics, top-level bedrooms, within your walls and in trees.

Roof rats are known to avoid new objects and foods within their living area; therefore, baited traps can go undisturbed for days until their caution is replaced by familiarity or pure hunger.

Female Roof rats have up to 5 litters per year, with up to 8 young each instance.


The House Mouse, Mus musculus, is an adaptable creature that can live in a variety of environments – within residential and commercial structures, fields, parks, and agricultural lots. Mice are usually light brown or gray. Adult mice can be up to 7 inches long, including the tail. Female mice produce 5-10 litters of up to 6 young per year.

Mice will eat the same foods as humans, pets and other animals. Consequently, mice can contaminate these food sources with pathogens that lead to salmonellosis (food poisoning).

Like the Roof rat, mice are good climbers! They can scale a rough vertical surface. Mice can also jump up to 12 inches. Because mice are small, they have been known to crawl through openings as small as 1/4 inches in diameter.

Signs to Watch For

Indicators that rodents are on your property:

  • “Browning marks” at entry points that rodents use – a brownish yellow residue left from dirt on their bodies as they squeeze through.
  • Rodent droppings near pet food and water dishes.
  • Nests made with shredded paper, cloth or fibrous materials.
  • Sounds within your home just after dusk.
  • Gnaw marks on wooden fixtures and doors made when rats enlarge entry points.

Rodent Control

A professionally-trained eye is needed to identify the smallest entry points that rodents will use to enter your property. Call us at 714.862.9687 to start expert rodent control and rodent exclusion services.

Because rodent populations grow quickly, it is important that you have a trained professional address the problem as soon as possible. After extraction and cleaning, we use a variety of rodent exclusion methods – each with a 1-year warranty.

These preventative measures can make your property less attractive to rodents:

  • Bring pet food and water indoors between dusk to dawn
  • Secure trash cans with tight lids
  • Remove fallen fruit and other food sources from your grounds
  • Stack firewood & other items tightly – about 18 inches from the ground
  • Ensure screens and vents are securely fastened and free of holes and damage
  • Ask a professional to inspect your property for signs of activity and possible entry points

Rodent FAQ

What kind of traps do you use? Live or lethal?

We prefer to use lethal snap traps because they are the most effective method of extermination. We can use live trapping methods whenever necessary, such as in larger infestations where the trap needs to capture several rodents between each visit.

Is this a permanent fix? Will the rats come back to my home?

Our treatments are geared to completely solve your rodent problem. We offer a 1-year warranty on our exclusion work; so, if, within 1 year, a rodent uses an entry point that we have repaired, we will fix it for free.

How long does it take to rid my home of rodents?

Every job is different. Depending on the size of your infestation and other factors, the extermination process may be as fast as 1 day or as long as 1 month. We are determined to fix your rodent problems, and we are proud of our 100% success rate!

How many rodents are usually in a house?

On average, 3-5 rodents. The sooner we address the problem, the quicker the solution.

What attracts rats?

Rats attract rats! From browning marks to urine and feces, rats leave scents that attract other rats. Of course, we recommend cleaning and disinfecting your home after treatment to prevent future infestations.
