Rats are large rodents that live in the Dallas area and across the United States. These nocturnal pests are destructive and create unsanitary environments when they infest residential homes. Urine and feces are of serious concern because of the rodent’s tenancy to get into food and share living space with humans. Their strong teeth can chew through wires, causing electrical outages and problems. Rat infestations are much more challenging when it comes to eliminating an active issue, which is why it’s imperative to address rat activity the moment it’s observed.

What kinds of rats live in Dallas?

Both residential homes and commercial structures can suffer from rat infestations and activity. In the Dallas area, the most common are Norway rats and roof rats. They are widespread across the United States, causing damage and creating unsanitary conditions wherever they go.

Norway Rat

Norway rats are large rodents, measuring 7-9.5” long with brown and black fur. Their diet consists of fish, nuts, cereal grains, and meats. When Norway rats move indoors, they commonly nest on the lower levels but if the population is too large, they may be found in the attic and ceiling areas. Their nests are built from soft material like paper or grass chewed into small pieces they gather from surrounding areas. Did you know that Norway rats are excellent swimmers? According to Columbia University, migrating rats can swim up to half a mile and survive by treading water for 3 days.

Roof Rat

Roof rats are the smaller of the two, measuring 6-8” long. They are brown and black with a long tail, large ears, and large eyes. Have you ever heard of ship rats or black rats? These are just nicknames for pesky roof rats. Roof rats get their name because they are especially good climbers, often found in spaces up high such as attics and drop ceilings, and cabinets. Their diet consists of a wide variety of foods including berries, nuts, slugs, and citrus.

How can I tell if I have rats?

Rats are nocturnal, with their peak activity at dusk or before dawn. When the population is large or they are disturbed or hungry, you can see activity during the day. If you see rats during the day, the infestation is significant and you should call Certified right away to handle the problem before it escalates.

Norway rats and roof rats will leave a hind foot track of about 3/4-1” where a mouse’s track measure’s 3/8” or less. Rats will also drag their tails, leaving a line-shaped mark between their feet tracks. Unscented baby powder or flour, lightly sprinkled can help you determine tracks and their runways as they cross suspected areas. They gnaw holes about 2” or more in diameter with rough edges to create entry points around your home and into trash cans. Rat burrows can be found along foundations, or beneath rubbish and shrubbery. If the burrow is active it usually clear of vegetation. Rat runways are smooth and well packed. Indoors, these runways are free of dust and dirt.

Why do I have rats?

Rats will seek food outside, but many times will come inside at night to forage for food and return to their burrows. They can travel hundreds of feet which could mean that you are suffering from your neighbor’s rat issue. Needing a water source, they can obtain water from toilets, sinks, rain puddles, or condensation from utility pipes. Their nesting burrows on the outside are often along the foundation of walls. As the rat family grows, more burrows are built, resulting in a network of underground tunnels. Outdoors, rats scavenge for fruit from trees growing on your property, and even dog droppings.

Why should I be concerned with rats?

Rodent control is a serious matter. They pose a serious threat to crops, structural materials, clothes, documents and electrical wirings. Rats and mice also endanger your health and well-being by carrying diseases and creating unsanitary conditions. Rats may bite or chase you if they feel threatened. Rat-bite fever is a major concern when it comes to rat scratches, bites, or consumption of food that has come into contact with rat droppings or urine. Symptoms of rat-bite fever include rashes on the hands and feed, sore throat, vomiting, fever, and muscle pain. If left untreated, rat-bite fever can cause serious health implications or even death. They prefer to gnaw on wood in spots such as doors, corners, and ledges, but can damage electrical wiring.

Rats also pose threats to your health and home by being frequent carriers of ticks and fleas. Fleas that fall off of the rodent can begin breeding in your home, causing an additional unpleasant pest issue.

How can I get rid of rats?

The best way to avoid a rat infestation is to prevent them from entering in the first place. You can prevent rodent infestations by ensuring that all of the cracks, crevices, gaps, or other vulnerabilities on the exterior of your home are properly sealed. Food that’s stored around your home in easily penetrable containers such as sugar and cereal should be moved to air tight containers. If you find contaminated food, discard it immediately and wash your hands. Ensure that all leaky or broken pipes are repaired. Another step towards rat prevention is to secure your trash can lids.
