Are Rats Dangerous? 8 Clear Reasons Why They Are!

8 Reasons Why Rats Are Dangerous Infographic

1. Damages to your home

Rats are well known for being able to chew through just about anything!

They have teeth that can bite through furniture, wires and cables, some parts of your home and even your clothes.

As rats can chew through quite a few items, there is a possibility that they will chew through structural items in your home. I am talking about wooden beams, footings, even concrete. You don’t need me to tell you how costly that can be!

It may start as a small gnaw mark, but that will get bigger, and bigger. The weather will make it worse too. Eventually, it will become weak enough to crumble apart.

How dangerous are rats? When you consider the damage they can do to your property, rats can be very dangerous!

2. They bring diseases

When considering why rats are dangerous, it is prudent to remember that rats can carry diseases in with them, and some of them can be lethal to humans, and other animals (your pets, for instance). These diseases are lethal to humans, for example, salmonellosis and bubonic plague (spread by the fleas that were carried by rats).

The plague is so dangerous it killed about 60 percent of the population in Europe during the 14th century. How dangerous are rats? Considering this info, I would say they are dangerous!

3. Pre-poisoned rat spells danger

Imagine this: Your neighbor has identified a rat problem in your area. They want to get rid of the rats to clear up your neighborhood and make the streets just that little bit cleaner.

What does he do?

He sets up a few rat traps and fills them with poison.

Next thing you know, that rat is getting close to your house, and your pet is chomping at the bit to grab hold of it. If your pet takes a chunk out of the rat, they could be affected by the poison and may end up needing emergency veterinary treatment, or maybe die.

Not only that but if a rat gets in your cavity walls and the poison takes effect, you have a dead rat odor taking over your home!

4. Can cause electrical issues/house fire

We have already discussed the fact that rats love chewing on tons of items. I also mentioned that rats can chew on cables.

See where this is going?

Potentially, a rat could chew through an electrical cable which may start a fire in your home.

Are rats dangerous? Well… if they can start a fire in your home, at any time, they are dangerous as far as I am concerned!

5. Infestation of fleas

Fleas are totally invasive and spread like wildfire!

Rats are well-known flea hosts. History credits rats with being the reason why the plague killed so many folks all that time ago.

How? Because the plague was spread via fleas that hitched a ride on the back of rats.

Rats were able to help the fleas travel fast.

6. Cornered rats get aggressive

Rats can be dangerous especially when they feel they have been threatened. A cornered rat is a dangerous rat!

They can and will bite and scratch you thus transmitting diseases to your family.

Although the bite is not fatal, some diseases that rats transmit can be. This is especially true for infants.

They also contaminate your food and run around the kitchen in areas where you prepare your food. Ingesting the contaminated food and preparing meals where the rat has trodden on can be dangerous to your health.

7. Ticks and associated diseases

Rats carry fleas, we have discussed that above. What else do rats carry that make them dangerous?

Ticks is the answer. Ticks are really annoying little critters that hook into you by burying their head under your skin to live off your blood supply. As if that wasn’t bad enough, they also have the potential of carrying diseases too! Ticks can carry Lyme disease, which if left, can cause some very serious health complications. 

The tick is dangerous, the rat carries the tick. Therefore, the rat is dangerous.

8. A dirty house means other health hazards

Rats make your house dirty and a breeding ground for other pests like cockroaches.

Having a dirty house also encourages other critters, like bed bugs! Bed bugs are very fast and aggressive breeders and they will quickly take over an environment.

When other bugs begin to infest your home, you need to step up and take back control before your health, and the health of your loved ones is affected.
