They must be. We don’t go into the treed area very much, but we probably need to just spray our fenced part of the yard and brush with permethrin. This will have taken both cats in 6-weeks. We were using frontline plus for flea & tick once we realized the Chesterin was flea only. I still found a tick on her so switched her to a sesestro collar that’s supposed to repel them. I guess it was too late.
We’ll have to make sure my husbands kids don’t leave the yard since they’re so bad. I didn’t even think about us watching out for Lyme.
