Rodents can cause damage to property beginning with attics and crawl space, create unsanitary living conditions and even carry diseases that can make you and your family sick. Rats can climb pretty much any surface and get wherever they want to go. They can squeeze through amazingly small holes and gaps. Sounds of scratching or movement are common signs of infestations. Mice tend to leave very small 1/8-inch droppings, while rats leave slightly larger, greasier waste that is about 1/4 inch to 5/8 in size. Squirrels have the largest droppings at around 1/2 inch to 1 inch.
You may not be able to find the place where your pests got in on your own, which is part of the reason why a professional wildlife control service is usually needed to successfully deal with rodents. The cost of removing rodents from a home varies, but typically it costs between $300 and $500. Normally, there is a fee of $75 to $125 for an initial inspection to determine what animals are present, where they are located and how they got in. Then, there is normally a fee to set the traps and a fee for each time that the pest control agent returns to remove an animal.
