Some methods to repel squirrels include traps, natural repellents, chemical repellents, electronic repellents and mesh fencing. These methods can vary in effectiveness depending on the type of squirrel and the severity of the squirrel problem.
Live squirrel traps are useful for catching small numbers of squirrels. Identify where the squirrels are entering, place the trap along their path and bait it with sunflower seeds or squirrel bait. Once the squirrel is trapped, it can be safely and humanely removed.
Cayenne pepper and chili powder are effective natural squirrel deterrents. Simply dust the powder on plants or around areas where squirrels enter. A spray composed of hot sauce, water and a few drops of mild dish soap is also effective.
Chemical repellents come in both liquid and granular forms. Liquids can be sprayed onto surfaces, while granular repellents can be sprinkled around the perimeter of the yard. Squirrels are persistent, so using the two repellents in tandem can be an effective choice.
More expensive electronic repellents deter squirrels using noise, motion and bursts of water. These devices are more environmentally friendly than chemical repellents and can still be placed in a variety of locations.
Mesh fencing is a versatile choice that can deter squirrels from structural openings. Fencing can be positioned under porches or around gardens to keep out squirrels.
