How Do You Know If You Have A Rat or A Mouse?

Sep 27, 2019 | Pest Control, Wildlife

Signs of a rodent infestation are pretty easy to spot – droppings in the house, chew marks, gnawed wood, and scratching and squealing sounds at night are all pretty good indicators of a rodent problem. Before deciding on a course of treatment, however, the first step is determining which type of rodent you have. So how do you know if you have a rat or a mouse?

Mice:

Mice are small rodents, usually about 2 to 4″ in length, with thin, long, slightly hairy tails. They have triangular shaped noses with long whiskers and large floppy ears. Mice can be brown, gray, or white in color. Mice droppings are small and smooth with pointed ends, usually about 1/8 to 1/4″ in length. They leave anywhere from 40 to 100 droppings per day. Mice prefer cereal grains or plants but will eat almost anything. They are nocturnal and tend to be bolder than rats. They are curious and will explore new things, making them easier to trap. They are skillful climbers and their small size allows them to access more areas of your home.

Norway Rats:

Norway rats are larger rodents, usually weighing about 11 ounces and measuring 7 to 9 inches in length. They have heavy, thick bodies that are brown in color with black shading and shaggy coats. Norway rats have blunt, rounded noses and short ears. Their tails are thick, hairless, and scaly and are dark colored on top and pale underneath. Norway rat droppings are brown and blunt on both ends and they leave anywhere from 20 to 50 droppings per day. They prefer fresh grains and meat but will eat just about anything. These rats typically live in burrows and prefer lower levels of homes and buildings. Norway rats are nocturnal and are more fearful and cautious than mice, making them more difficult to trap. They can climb but prefer to stay closer to the ground.

Roof Rats:

Roof rats are smaller than Norway rats, weighing about 7 ounces. They have light, slender bodies that are gray in color with smooth coats. They have thick, hairless, scaly tails that are dark in color. Roof rats have pointed snouts with large ears. Roof rat droppings are dark with both ends pointed. They will also eat just about anything but prefer fresh grains and meat. They are nocturnal and timid in nature. Because of this, they can be difficult to trap. They are excellent climbers and are more often found nesting in walls, attics, and trees.

Rodent Control:

Regardless of whether you have mice, Norway rats, or roof rats, all of these rodent species can cause damage to your home and property by chewing through wires, pipes, insulation, and drywall. They can also cause damage to furniture and carpets. All rodents can contaminate food and countertops. Serious diseases caused by rat droppings and mouse droppings include Hantavirus, salmonellosis, and more. They all reproduce quickly and a minor problem can become a major infestation in no time.

Keeping these pests out of your home is critical to helping protect the safety of both your family and your property. Here are some rodent control tips you can implement in and around your home:

Put A Lid On Your Trash: If possible, use trashcans made of metal with snug fitting lids. If you must use plastic, make sure there are no holes in it.
Don’t Leave Pet Food Out: Store pet food and birdseed in glass or metal containers with tight lids. Make sure to remove them at night and store them away until morning. Make sure to pick up any fallen fruit or nuts off the ground outside your home, as well. Remove standing water from bird feeders.
Elevate Your Compost: Raise your compost container at least 1 foot off the ground.
Keep Your Garage Clean: Rodents like to eat lawn seed, tulip bulbs, bone meal, and other items frequently used in gardening. Make sure they are stored in glass or metal containers with tight lids. Keep firewood a good distance from the house. Organize and store boxes in the garage off the ground to eliminate nesting places.
Clean The Kitchen: Keep food stored in tightly sealed containers. Clean up spilled food and crumbs nightly.
Keep Your Home Maintained: Make sure openings around your home are properly sealed. Keep your gutters clear of debris and water. Screen your attic vents. Keep screens on windows and doors in good repair and replace when needed.
Call A Pro: If you suspect you have a rodent problem, call a professional pest control company or a professional wildlife removal company who can evaluate your home and provide you with a comprehensive treatment and exclusion plan.

Fact or Fiction: Rats Can Make You Sick

Jul 31, 2019 | Pest Control, Wildlife

FACT. Rats are one of the most common pest issues homeowners face. Rats are known for being destructive by gnawing on structures in and around your home including utility pipes, wood structures, and wiring. In addition to the structural damage rats can cause, it is also possible for rats to pose serious health risks to humans. Diseases caused by rats can be transmitted through bites or scratches. Rat feces illness can be transmitted to humans through rat droppings and urine left around your home. Humans can also get sick through contaminated food caused by rats running across countertops where food is later prepared.

Just how sick can rats make you? Here are some common rat-borne diseases found in the United States.

Hantavirus Pulmonary Syndrome

Hantavirus pulmonary syndrome is a viral illness spread by deer mice, cotton rats, rice rats, and white-footed mice. HPS is spread by direct contact with rodents or their urine and feces, by breathing in dust contaminated with urine or droppings, or by bite wounds. Symptoms in the first phase of the virus include fatigue, fever, muscle aches, headache, dizziness, chills, nausea, vomiting, and abdominal pain. The symptoms then progress to coughing and shortness of breath. HPS is a severe and sometimes fatal respiratory disease with a 38% mortality rate. There is no specific treatment, cure, or vaccine for hantavirus infection.

Leptospirosis

Leptospirosis is a bacterial disease spread by rodents worldwide by either eating or drinking food and water contaminated with urine or contact through the skin or mucous membranes with water or soil that is contaminated with urine. Without treatment, leptospirosis can lead to kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, respiratory distress, and even death. Common symptoms include fever, chills, headache, muscle aches, abdominal pain, vomiting, jaundice, diarrhea, and rash. The symptoms are often mistaken for other illnesses. If not treated, the second phase of symptoms includes kidney or liver failure or meningitis. The disease lasts between 1 and 3 weeks. Leptospirosis is treated with antibiotics.

Rat-Bite Fever

Rat-bite fever is a bacterial illness spread by rats and possibly mice. The disease occurs worldwide and is spread through bites or scratches from an infected rodent, contact with a dead rodent, or eating or drinking food and water that is contaminated by rat feces. If not treated, RBF can be a serious or even fatal disease. RBF is not spread from one person to another. The early symptoms of RBF can be similar to the symptoms of other medical conditions. Common symptoms include fever, headache, muscle pain, headaches, vomiting, joint pain, and rash. If the illness progresses, more severe complication can arise such as abscesses, hepatitis, kidney infections, pneumonia, meningitis, or infections in the heart. RBF is treated with antibiotics.

Salmonellosis

Salmonellosis is a bacterial disease found worldwide that is spread by rats and mice. Salmonellosis is spread through eating or drinking food and water that is contaminated by rat feces. Salmonellosis is an infection caused by the Salmonella bacteria. Although commonly spread when a person eats contaminated food, the bacteria also can be passed between people and animals. Common symptoms include diarrhea, vomiting, fever, and abdominal cramps. Salmonella infections in people usually resolve within 5-7 days, and most do not require treatment other than drinking plenty of fluids. People with severe diarrhea may need to spend time in a hospital getting rehydrated with intravenous fluids.

Rat-borne diseases can cause serious and sometimes fatal illnesses in humans. The best way to avoid these diseases is to prevent rats from infesting your home in the first place. Here are some common home rat prevention tips:

Put A Lid On Your Trash: If possible, use trashcans made of metal with snug fitting lids. If you must use plastic, make sure there are no holes in it.
