.....Haven't read anything here but the comments on this page, but I'll add my $.02.....Seems to me that earlier on in the spring, ticks were just as abundant as ever, but recently I've noticed a substantial decrease in them. The Lab is just not coming home with nearly as many as he usually does after a romp or two in the fields out back, and I'm not seeing them on myself much either. Hey.... believe me, I'm sure not complaining about it......
