i've been getting some unfriendly visitors for the past couple weeks who keep digging up my lawn. we installed an automatic motion sensor light but i guess it doesnt scare them away. ive stayed up a couple nights and found that they are mainly racoons and an occasional visit from skunks. is there any form of animal repellent that you guys/girls have found successful? i think they're eating the snails, so we tried using the snail killer pills but i guess they're eating something else now. thanks for your help.
