Do Rats Bite Humans at Night? Preventing and Treating Rat Bites

Do Rats Bite You When You're Sleeping?

Rats are nocturnal creatures that can become active at night while you're sleeping. Although rare, some people awaken to find mysterious bites or scratches and wonder if a rat was the culprit. Rats have sharp teeth and claws that allow them to chew and scratch, potentially causing injuries. However, rats typically prefer to avoid humans. Here's what you need to know about rat bites and how rats interact with sleeping humans.

Are Rat Bites Common?

Rat bites are relatively uncommon. Rats prefer to avoid humans and will usually only bite if they feel threatened or cornered. Bites most often occur when someone reaches into an area with a rat, such as behind a wall or under a sink, and startles the animal. Rats may bite to defend themselves when they cannot escape.

People who keep rats as pets can also get bitten occasionally. This happens if a hand gets too close to a rat's face and startles it. Pet rats may misinterpret a hand moving quickly near them as a threat.

Wild rats have little desire to interact with humans, especially when we're sleeping. They prefer to find food away from where people are located. So the chances of getting bitten while sleeping are very low.

Why Might a Rat Bite You in Your Sleep?

There are a few scenarios in which a rat may bite a sleeping person:

• The rat is searching for food on the bed and gets frightened when the person moves in their sleep. Defensive biting may occur.
• A person rolls over on top of a rat that was resting on the bed, scaring the rat and causing it to bite.
• A pet rat that is loose in a bedroom bites a sleeping owner after landing on the bed and getting near their face.
• A mother rat is protecting her young that are nesting on the bed and bites an unsuspecting sleeper.

However, even in these cases rat bites are uncommon. Rats are wary of humans and do not want to confront or bite them. Bites seem more likely to happen when a rat feels cornered or threatened.

Signs of a Possible Rat Bite

How can you tell if a wound is from a rat bite versus another insect or cause? Here are some signs that point to a possible rat bite:

• One or two puncture marks from the rat's front teeth.
• Scratch marks in addition to punctures from the rat's claws and feet.
• Slight tearing of the skin around the bite marks.
• The wound is on an exposed body part like the face, neck, hands or feet.
• The bite happened at night while sleeping.

Rat bites can range from minor punctures to deeper wounds if extensive biting occurred. Defensive bites often just break the skin lightly without deep punctures. The bites and scratches may be painful and continue oozing for some time.

Treating Rat Bites

As with any animal bite, rat bites require proper first aid and monitoring to prevent complications:

• Wash the wounded area with soap and water to lower infection risk.
• Apply antibiotic ointment to help prevent bacterial infections.
• Cover with a sterile bandage and change daily.
• Watch for signs of infection like increasing swelling, redness, warmth and pus.
• Seek medical care if the bite appears infected or you have a fever.

Tetanus shots may be recommended if you haven't had one within the past 5 years. People with weakened immune systems may require antibiotics. Overall, rat bites heal well with proper hygiene and care.

Risks of Rat Bites

While rat bites pose minimal health risks to most people, there are some concerns to be aware of:

• Infection - Rat mouths contain bacteria that can enter a bite wound and cause infection. Look for increasing redness, swelling, warmth and pus.
• Rat-bite fever - Rare bacterial infections transmitted through rat bites or scratches. Causes fever, rash, joint pain and vomiting.
• Plague - Extremely rare cases of plague transmitted by infected rat fleas. Causes high fever, chills, nausea and swollen lymph nodes.
• Rabies - Very rare for a rat bite to transfer rabies. Rats are not typical carriers of the rabies virus.

See a doctor promptly if signs of infection develop after a rat bite. Serious infections from rat bites are uncommon, especially if the wound is cleaned.

Preventing Rat Bites at Night

To avoid being bitten by a rat in your sleep, follow these tips:

• Inspect for signs of a rat infestation and use extermination methods if needed.
• Keep food stored away and crumbs cleaned up to avoid attracting rats.
• Seal any plumbing holes or cracks rats could use to enter the bedroom.
• Keep pet rats secured in a cage at nighttime rather than letting them roam free.
• Use sheets and blankets rather than sleeping directly on a mattress.
• Move bed away from walls and clutter rats could hide in.
• Consider traps around legs of bed to protect at night.

Rats shy away from humans, especially when sleeping. But take sensible precautions to make your bedroom less appealing if a rat problem exists.

When to Seek Medical Care

Most rat bites can be treated effectively at home. But talk to your doctor if:

• The wound shows signs of infection like increasing pain, swelling and pus.
• You develop flu-like fever, joint pain or rash after the bite.
• The bite is on your face or neck near major blood vessels.
• You have a compromised immune system that makes infections more risky.

Seeking prompt medical attention is wise if the bite appears infected or you feel ill after being bitten. Healthcare providers can properly clean the wound, assess for infections and provide antibiotics if warranted.

How to Keep Rats Away

To prevent rat bites, it's important to deter rats from taking up residence in and around your home. Here are some tips to keep rats away:

• Seal any holes or entry points on the exterior of the home using steel wool, caulk or cement.
• Use weather strips on doors and door sweeps on garage doors to block gaps.
• Store food like pet food in sealed metal or plastic containers.
• Clean up any spilled food right away and keep the kitchen tidy.
• Take out the garbage regularly and keep trash cans tightly closed.
• Stack woodpiles and debris far from the house.
• Trim back bushes and vegetation so rats have fewer hiding spots.
• Use traps or baits to kill and remove any invading rats.

Keeping your property clean and free of places rats can nest and find food goes a long way in preventing infestations. Traps and pest control can also help get rid of any rats on your property.

When to Call a Professional Exterminator

It's a good idea to enlist a professional exterminator if:

• There are signs of a substantial rat infestation like droppings, burrows and numerous sightings.
• DIY traps and preventive measures have not resolved the rat problem.
• The property has conditions very favorable to rat infestation that require expert solutions.
• You want to fully eliminate rats and prevent recurrent infestations.

Professional exterminators have the skills and chemical treatments to fully eliminate rat infestations. They can also identify and seal up hard-to-find entry points. For severe rat problems, hiring a pest control expert is often the best solution.

Diseases Rats Can Carry

Rats can potentially transmit diseases through bites as well as contact with their feces, urine and fleas:

• Leptospirosis - Bacterial infection spread through rat urine that causes fever, chills, vomiting and diarrhea.
• Rat-bite fever - Rare bacterial illness caused by infected rat bites or scratches.
• Salmonella - Food poisoning resulting from contact with rat feces and contaminated food.
• Hantavirus - Rare viral disease spread by breathing in dust from infected rat droppings.
• Plague - Deadly bacterial disease transmitted by fleas that have fed on infected rats.

While alarming, transmission of these diseases from rats is very rare, especially in developed countries with modern sanitation practices. Practicing good hygiene around rats can help reduce disease risks.

Protecting Yourself from Rat-Spread Diseases

You can take these precautions to avoid diseases carried by rats:

• Use traps and bait to control rat populations on your property.
• Seal up any entry points so rats cannot get inside.
• Wear gloves and mask when handling dead rats or cleaning droppings.
• Disinfect areas where rats have been with bleach solution.
• Have sick or dead rats tested by professionals for disease.
• See a doctor if you have flu-like symptoms after exposure to rats.
• Practice good hand hygiene after contact with areas rats may frequent.

While concerning, rat-borne diseases are rare and avoidable. Keeping rats away from your home and practicing good hygiene are the best protections.

How Rats Get into Your House

Rats are adept at finding ways to sneak into houses in search of food and shelter. Here are some common entry points rats use:

• Gaps around pipes, utilities, vents and wires entering the home.
• Cracks in the foundation or exterior walls of the home.
• Openings where cables and pipes enter the walls inside.
• Spaces under doors if sufficient clearance exists.
• Around the edges of windows or doors that do not seal properly.
• Loose floorboards or holes chewed in wooden floors.
• Access through the attic or walls if screening is damaged.

Rats can squeeze through incredibly small spaces as narrow as a quarter inch. Sealing up all possible entry ways is crucial to preventing rats indoors.

Preventing Rats from Entering Homes

Here are some tips to rat-proof your home:

• Inspect the exterior of the home for cracks and fill them in with steel wool or caulk.
• Use cement or hardware cloth to cover larger gaps around the foundation.
• Install weather stripping around doors and door sweeps on garage doors.
• Seal openings for utilities with copper mesh, caulk or concrete.
• Use steel wool or expandable foam to fill cracks inside around pipes.
• Repair any openings in walls or floors that rats could expand.
• Ensure vents, chimneys and screening have no damage.

Inspecting inside and out and sealing every possible entryway is the most effective approach to keeping rats out of a home.

How to Catch a Rat

If you have spotted signs of rats in your home, using traps is an effective method to catch and eliminate them. Here are some tips for trapping rats successfully:

• Use traps designed for rats rather than mouse traps which are too small.
• Place traps along baseboards, in corners, or areas with signs of activity.
• Bait traps with peanut butter, chocolate, dried fruit, nuts or bacon.
• Set traps close to walls so rats pass directly over the traps.
• Put down a large number of traps to catch multiple rats quickly.
• Check traps daily and replace bait as needed until no more rats are caught.
• Wear gloves when disposing of trapped rats to avoid diseases.

Trapping is often the quickest and most effective way to eliminate a rat infestation. Combining traps with preventive measures to block rat entryways provides the best control.

When to Call a Professional Exterminator

Consider hiring a professional exterminator if:

• An extensive rat infestation exists inside the home.
• Traps and DIY approaches have not resolved the issue.
• Access points are hard to locate on your own.
• You want guaranteed elimination of rats.

Professional exterminators have specialized training, equipment and chemicals for getting rid of rodents. For major rat problems, calling a pest control expert often provides the best results.

Rat Droppings Identification and Dangers

Rat droppings can carry diseases and pose health risks. Here's how to identify rat poop and safely clean it up:

Identifying Rat Droppings

Rat droppings typically have these characteristics:

• Cylindrical shape with blunt ends.
• Size of a large grain of rice up to 3/4 inch long.
• Shiny black or brown in color.
• Possible visible insect parts or fibers from rodent's diet.
• Found in small piles near nesting areas and food sources.
• Produce a musky urine-like odor.

Knowing how to identify rat feces can confirm if rats are present and help pinpoint nesting areas for elimination.

Diseases Spread by Rat Droppings

Coming in contact with rat droppings can potentially expose you to:

• Hantavirus - rare viral disease transmitted by breathing in dust from infected droppings.
• Leptospirosis - bacterial infection spread through rat urine in droppings.
• Rat-bite fever - bacterial disease from infected rat droppings entering cuts or scrapes.
• Salmonella - food poisoning caused by droppings contaminating food or surfaces.

While risks are low, caution should be taken around accumulated rat droppings, especially in confined spaces.

Cleaning Up Rat Droppings Safely

To safely clean rat droppings:

• Wear gloves, mask and eye protection.
• Do not stir up dust from droppings.
• Soak droppings in disinfectant or bleach solution before wiping up.
• Use paper towels to pick up soaked droppings.
• Seal waste in plastic bags for disposal.
• Wash hands thoroughly afterward.

Proper clean up and precautions can reduce health risks from rat droppings. Consider hiring a professional if droppings are extensive.

Can a Rat Kill a Human?

Cases of rats killing humans are extremely rare. However, rats can transmit diseases through their bites and scratches in rare cases that potentially could be fatal if left untreated.

Direct Rat Attacks

There are a few documented instances of rats directly attacking and killing humans, although these involve extenuating circumstances:

• A newborn baby left unattended was attacked and killed by rats in South Africa in 2011.
