Trying to get rid of raccoons yourself is not as easy as all the DIY tips make it seem. Raccoons repellents aren’t very useful and it’s highly likely that you’ll need to trap the animals to get rid of them.
Removing raccoons isn’t as simple as buying a trap and catching the raccoon. There are a lot of different factors involved. Including:

• Identifying how many raccoons are nesting
• Access points (how they’re getting into space)
• Types of trap
• The best bait to use
• Where to place the trap

You’ll also need to know what to do with the raccoon once you’ve caught it. Your local state laws will limit your options here. Most will only allow for on-site release or on-site euthanasia. So once you’ve captured the raccoon, you’ll have to release the raccoon back onto your property or humanely kill the raccoon yourself.
Then there’s the added complication of baby raccoons. If you have a raccoon nesting in your attic, it’s probably a mother and her kits. If this is the situation with your raccoon squatters, then hire a professional straight away.
Once you’ve removed the raccoons, you’ll need to repair or seal up their access points to prevent other animals from occupying the vacant space. You’ll also have to perform a thorough cleaning and disinfect the attic where they were living. Raccoons are carriers of parasites and disease, both of which will be left behind in their fecal matter, even after the raccoon is gone.
