Like squirrels, they enter homes and are found in attics. In the absence of Norway rats, or if their population grows, they can be found in burrows or piles of rocks.

Rat Poison Pros And Cons

Ken Brown, owner/operator of Eco-Logic Management , describes how he uses rat poison:

I put out bait boxes, which are boxes that secure the bait inside. The bait contains a pheromone that attracts the rat to it.

After the rat eats the bait, it slowly dries the rat out over the course of about three days until they basically fall asleep, usually in their nest.

“Boxes are usually placed near AC units and pool pumps because that wiring is a big target for rats to chew on.

Brown says the pros of using rat poison include:

  • Bait boxes lock with a key so that pets and children cannot get into them.
  • The poison can work on many rats at once.
  • The boxes are regularly maintained by a licensed exterminator.

As for cons, Brown said bait boxes cost more than buying and maintaining old-fashioned mouse snap traps, rats may die in a nest that is in the homeowners attic and it will smell for about three days, and once in a great while a rat will die out in the open.”

How Do Roof Rats Enter The Attic

Roof rats are expert climbers they travel along power lines with ease and can scale a brick building with no problem. Roof rats can also jump 2 feet high, and can clear a 4 foot distance from one standing point to another.

Roof rats only need a half-inch wide hole to gain access to a building. A nickle-sized hole can either be squeezed through or simply chewed by the roof rat to make access a little easier. Roof rats can chew through a variety of materials: drywall, plastic, wood, aluminum siding.

Roof rats will mark entry holes as their territory using the secretions from their fur. This scent remains long after your tenant roof rats are gone. This scent serves as a signal to other scouting roof rats that your place was once approved by former roof rats.

Lastly, since roof rats have teeth that never stop growing, they must gnaw to survive. Chewing through materials is necessary for the roof rat, and an attic provides plenty of areas for chewing. Wood beams, vents, pipes, shingles, and unfortunately live wires are all susceptible to roof rat gnawing. Roof rat incisors would grow in a spiral if they didn’t chew to wear them down.

Most Common Types Of Rats In North America

When it comes to rat infestations in America, there are three species that are the most common. The two most common species are Old World rats that came to America as stowaways on ships. Roof Rats have largely stayed near the places where they arrived and are most common in seaports, coastal cities, and the American South, where they spread with cargo boats traveling the river network.

Norway Rats are the most common species throughout the United States and are particularly widespread in urban areas. You can find them just about anywhere, and the wide footprint of this species means that infestations overlap with other Old World rats as well as new world species.

The third major rat species in America is the Pack Rat, a New World species that adapted to life in the deserts of the Southwest. While they dont follow human settlement in the way Old World rats do, expanding urbanization in Nevada, Arizona, and other states in this area has made Pack Rat infestations more common.

Norway Rats

Rattus Norvegicus have brown fur and a long tail. While the scientific name of this species calls back to their common name, they actually arent from Norway. Where did Norway rats come from, then? Its likely that Norway rats actually originated in China, home of some of the oldest large cities in civilization. After flourishing in these cities, they spread to the corners of the earth.

Plaster Of Paris As A Rat Poison

If you want to kill a rat faster than baking soda, youll want to use Plaster of Paris. This substance is often used for crafts. It works with water and quickly becomes a moldable paste.

The good news is that you can use the same two recipes mentioned above to form bait balls.

But when choosing your peanut butter, you want to make sure that its not too oily. The reason is that the plaster will absorb the oil and then harden. The drier the peanut butter, the better. Youll need 3 grams of Plaster of Paris to kill a rat.

The idea is simple: rats consume the plaster, it enters the body and soaks up water, and the rats die from dehydration. Since the plaster will harden inside of the rat, it will also not be able to be digested.

Either way, the rat dies from either starvation or dehydration.

Youll definitely want to keep the plaster away from pets or kids.

Anytime that you use a poison, even one that is very strong and commercial-strength, youll want to make sure that you replace the poison often. The poison is almost always slow working, and it will take a few days of consumption to kill the rat.

Size will also play a major role in how long the rat will survive after eating the poison. If the rat is extremely large, it will take more poison to kill it.

Using multiple lures will allow you to attract more rats and ensure that the rats dont get tired of the bait.

Are Roof Rats Harmful

Pin on Rodent proofing

Any rat can become aggressive when threatened. They might bite you or pursue you. You could contract an illness like rat-bite fever if a roof rat bites you. Rat-bite fever symptoms might appear anywhere in a matter of days or weeks after the incident. Its important to recognize the symptoms because they can be present even after the bite has previously healed:

  • Joint and muscle aches.

Note that some infections caused by rats can kill people if not handled appropriately. They can infect people through their feces and urine. Although roof rats are yet to be linked to the Hantavirus pulmonary syndrome, you must still exercise caution when wiping up urine and excrement because you might have mistaken your rat infestation for something else. When people breathe air that has been around rat saliva, feces, or urine, they can contract the hantavirus.

Furthermore, fleas that previously fed on rats can make you sick. Diseases like tularemia and plague can be spread when a flea attacks a roof rat and afterward bites you.
