Bought seresto collar 4 months ago. Works very well for fleas, doesn't work for ticks.
Our house backs up to the woods and we have to deal with ticks 8-9 months of the year. This collar has had zero effectiveness against ticks. We have pulled ticks off our miniature schnauzer almost every day since the beginning of April. I was hopeful when my vet recommended the collar because in the long run it costs less than the topical drops. We haven't seen one flea, but it's a bust when it comes to ticks.
