Squirrels are especially difficult to control due to their persistence and speedy, acrobatic movements. It's most effective for homeowners to nip this in the bud by taking preventative measures from the bushy-tailed animals. Squirrels can cause substantial damage to yards, gardens, roof and attics. They're excellent chewers and are notorious for chewing their way into buildings at a fast pace, as they love being inside buildings. Once they gain entry, they move in to make a mess with their constant gnawing on fittings and structures.
Squirrels create a massive nuisance for many homeowners, they can be heard chattering or squealing from the attic, or scurrying around and knocking things over. They are not hard to see as they are active during the day, and some of their antics are: They eat some garden plants and ruin others by scurrying around them, Inside, they create a mess in attics with their urine and droppings, They chew on electrical wires and insulation, creating a fire hazard,They leave filthy tracks on your walls
Squirrels enjoy swinging from tree branches to get where they’re going. Be sure no tree limbs are hanging over your backyard and trim all branches within a few feet of the backyard. Install the type of fencing that may keep squirrels out, use materials that they can't climb or squeeze through the holes. Great examples are wire or plastic mesh fencing which bother squirrel paws. Purchase squirrel baffles and put them on your bird feeders to prevent squirrels from stealing bird seed. As soon as they find a food source, in your yard, they will just keep on coming. If it's possible with your garden size, you might construct a makeshift mesh lid to cover the backyard which you could pull on and off as needed. This is a costly solution however.
Basically, you will need to make sure that there isn't any openings through which squirrels can enter the home. Read more in my 10-step manual for How to eliminate Squirrels.
Do a comprehensive inspection of your property and determine any openings which lead into the attic and walls; check out the vents, roof and wood joints, and similar items.
Notice openings and weak, rotten wood on the outside. Climb in the attic and find gaps which light enters as possible entry points. Seal up attic vents with hardware cloth, because net cloths cannot keep squirrels out. Secure with basic nail guns and screws. Trim the limbs of all branches and trees within six to eight feet of your property, this is within leaping distance for a squirrel.
Prevent squirrels from climbing nearby trees by fastening a 2-feet metallic sheet around the back of the tree, about 7 feet above the ground. Spray a repellent over sealed openings and cover as much distance as possible. Buy a strong steel chimney cap and put it on tightly to cover the top of your chimney. Liquid and granular squirrel repellents can be found in stores. However, repellents rarely get the work done and there's not any proven one. Those wthat contain the active ingredient -- Capsaicin, are more likely to work. They have to be implemented and re-applied with the suggested consistency. The liquid repellents are sprayed on surfaces, bird feeders, roof, garbage cans, flowers, as well as trees, to discourage squirrels from chewing or digging. The granules are acceptable for indoor use in temperatures below 40 degrees.
