Alright so my filly was looking pretty scraggly shes wormed fed couldn't figure it out. Then I see her itching on the fence. I think ok lice. I check no lice, but then i feel all these little bumps. I look and shes full of TICKs. Big ones and itty bitty ones. (yes I have been itching for nonstop) I hate all those nasty little critters. Whats the best way to get rid of these pests? I treated her with equispot and its not working.
