Should I be concerned?

Potential health concerns
The Norway rat can be carriers of rat bite fever, cryptosporidiosis, hantavirus pulmonary syndrome, bubonic plague, typhus, toxoplasmosis, Q fever, and viral hemorrhagic fever. They can also contaminate food with their feces, urine, saliva, and the parasites that they carry with them.

What happens if left ignored?
Not only do Norway rats carry many diseases, but they also cause structural damage, they will leave holes in lawns, gnaw through electrical wiring, undermine building foundation and leave teeth marks on walls.

Habitat
Norway rats burrow underground near structures that can provide overhead shelter, they are nocturnal and are generally only active at night. Spotting a Norway rat during the day is a sign of a large infestation.

Behaviour
Norway rats breed rapidly, having five liters per year with up to 12 young each liter. The female’s gestation period is only 21 days, they reach sexual maturity at five weeks of age. Their life expectancy is 3 years, but most will not even make it 1 year

The Norway rat can produce an ultrasonic vocalization, as young rats, they use different ultrasonic cries to elicit maternal behavior, and to regulate their mother’s movements. Adult rats will also emit ultrasonic vocalization in response to danger from a predator.

They will sleep together and groom each other, they tend to play fight (going for each other’s throats), they will strike each other’s back if they are attacking.  

Diet
The Norway rat will consume anything, but their diets mainly contain cereals

Key tips for prevention
The best way to keep Norway rats out of your space is by sealing any holes or crevices. The body of a rat is extremely pliable and they could squeeze through spaces the size of a quarter. Making sure your home is sealed will help keep them out.

Keep counters and table tops clean, clean up spills and crumbs. Remove food sources, clean dumpsters regularly. Make sure trash in in tightly covered containers, seal and cracks or holes in foundation. Remove any standing water outside and do not leave doors open for any period of time.

Caution for self-treatment
If you notice a large number of droppings, then your rat problem could be bigger than you think. Rats are very shy of new object being introduced into their space. The traps you buy at the store may not be enough to treat your rat infestation.

Hire a professional pest service
A rat infestation poses many health risks and the potential to cause serious damage to your property. And because of their ability to quickly reproduce, their numbers can quickly get out of control. The best thing you can do is hire a professional service to solve your rat problem.
