MONKEY REPELLER is controlled by a device called an adaptor. After the MONKEY REPELLER is plugged into the electric mains, the garden, lawn, and yard will be protected for 24 hours at a reasonable cost. Its ultrasonic shield prevents stray pets (such as dogs and cats) and possible field rats, squirrels, deer, martens, bats, pigeons, and monkeys from invading your property aggressively.
Under the safety of the MONKEY REPELLER, those undesirable visits will never be a problem again.
