Spring is here. Winter is over, cold weather is leaving. However, with this comes squirrels also enjoying the warm weather. They will start to gnaw and your vents make very good chew toys. Once they chew the lead away the rain, which also comes with the spring, will start to leak into your roof. Dont let this happen, get some Critter Quitters and keep the vents safe.
