I absolutely HATE ticks!!! We have them so bad around here and Frontline doesn't even phase these nasty little creatures. I've stopped using it and now I spray my babies with a natural spray that truly seems to be working. I was iffy about trying it but I haven't found any ticks recently.
Also, let me add that my one baby girl Trixie tested postive for Lyme's Disease. Simply being bitten by a tick can produce a postive reading so further testing is required. After testing postive they did further testing on Trixie and it came up as a high positive. She had to be put on a certain type of medicine for a month and will be tested again in another 6 months. Tick bites should definately be taken seriously. Not all ticks carry diseases but it only takes one.
