They are very good about calling ahead and we’ve seen far fewer ticks so far this year than last…fall is worst so time will tell. Happy so far because, after such a wet winter was expecting tick increase. What’s extra great about this company is that a professional, knowledgeable person answers the phone or calls back immediately. With all the businesses I deal with, this is a rare delight. I’ve also used this company for ailing trees and bushes. Results are positive there also.
