3 Shocking Facts About an Indoor Rodent Infestation


Rats and mice don’t like the cold, which is why they seek warmth inside homes, offices and other buildings. Rats can get into a home through a half-inch hole while a mouse needs a quarter-inch hole. And, both of them will chew a hole until it’s wide enough to get through.

Worse yet!

Should they find food and water inside, the building can become infested. This is a real issue for homeowners.

While most people don’t like the idea of seeing a mouse or rat inside their home, the major concern is the damage these rodents can cause. What kinds of damage can a rat or mouse infestation cause?

Nesting & Chewing

Mice and rats are resourceful invaders and will use clothes, stored fabric, and newspapers – basically, anything they can easily chew through to construct their nests. Once rodents create a nest, they start on their chewing crusade, searching out items like electrical wiring, insulation, drywall and more. Wires damaged by rodents can lead to electrical problems and sometimes fires.  

Rapid Reproduction

Mice and rats can build up their populations quickly, especially if the home has a surplus of food and water for them to survive and thrive. It only takes a few months for the rodent population to multiply into a serious nuisance. Rodents reproduce rapidly, here’s the breakdown:

  • Mice – A mouse can have up to 10 litters in one year with at least six young in every litter. However, it’s not uncommon for a mouse to have 12 babies in a litter. It takes mice seven weeks to become adults, allowing more and more mice to be born in a short time.
  • Rats – Female rats can have seven litters in one year with a maximum of 14 young for every litter. Rats become adults in four weeks, which allows several generations of rats to be born during 12 months.

Of course, you’ve got to consider how many females are born in each litter – be it rats or mice. The number of rodents inside the home can grow exponentially in just one year.

Rodent Urine, Contaminated Air and Potential Diseases

Once these rodents have an established their nest – and potentially before it’s done – the mouse or rat will go looking for food and water in the home. While doing this, the rodent will litter their paths and hangouts with urine and feces, which contaminates everything within close proximity.  Now, it may not like seem like a big deal, but consider if these extremists get into your pantry or food storage areas. Anytime you come in contact with these areas you are exposed to potentially harmful bacteria.

You may think your boxed food is safe, but rats and mice have extremely sharp teeth. This allows them to quickly chew through bags and boxes.

Even with protective food and water storage containers, the reality is that rodents are dangerous. Simply breathing in dust or air tainted by rodent urine and droppings can spread illness or disease. Rodents can cause diseases such as salmonellosis, Hemorrhagic Fever with Renal Syndrome, Omsk Hemorrhagic Fever, Rat-Bite Fever, Arenaviruses, and Leptospirosis.

It is so important to take the necessary precautions to safeguard your home and family from a rodent infestation. Look for rodent deterrents and seal entry points to keep rodents from making your home, their home.
