You can deter squirrels by yourself. By using high-frequency sound devices, homeowners can ward off unwanted squirrels. Using these kinds of deterrents is extremely cost-effective, especially when the alternative is paying for professional removal.
Professional pest removal is best when it comes to removing squirrels from an attic. While sound devices may work, according to www.Squirrels.org, they are often effective for only a short period of time.
Having a professional remove a squirrel from an attic with one entry point will cost around $100, according to www.BatGuys.com. While a homeowner may prevent squirrels from entering using sound devices, the effects are often temporary. The cost of professional squirrel removal will increase based on the number of rodent entry points that need to be sealed.
