Raccoons are pretty from a distance, but when they move into a shed on your property, they become more of a nuisance than an admirable element of nature. Raccoons carry rabies and other diseases, they've been known to destroy property and eat homeowners' trash, and mothers can become quite vicious if they think their babies are being threatened. If there are raccoons living in your shed, follow these dos and don'ts:
DO: Call a wildlife removal company.
It's not a good idea to attempt to remove or eradicate the raccoons yourself. Trapping them may result in you being bitten, and if you are bitten, you'll generally need to have rabies shots -- which are neither comfortable or affordable! Leave the exterminating to the exterminators. If you are having trouble finding a wildlife handler in your area, call your local SPCA or Humane Society. They should be able to give you a number.
DO NOT: Get too close to the raccoons.
Once the wildlife exterminators have been called, you'll need to put off any activities you have planned involving the shed until they have cleared out the raccoons. Don't go in there for a lawn mower or rake if you fear it will disturb the raccoons. Put off cutting your lawn or borrow a mower from a neighbor for the time being. Even if the raccoons don't seem aggressive from a distance, they may be when you are closer to their nest.
DO: Keep trash sealed and away from the shed.
One reason the raccoons may have picked your yard could be easy access to food. They'll make a big mess out of your garbage if you are not careful. So, keep your trash in a covered container, and place a cinder block or something else very heavy on top of the lid. Raccoons have very agile hands and can pry a lid off a trash can if it is not weighed down adequately.
DO NOT: Assume they are gone for good once the exterminator leaves.
The exterminator will remove any raccoons from your property, but they won't typically take any steps to make sure new raccoons don't move in. That's up to you. Seal any holes in the shed wall that may have allowed the raccoons to sneak in, and install a light in your shed. (Turn the light on at night for a while -- it will make your shed less appealing to these creatures.)
