I fluke three times a year - around Oct, Jan, Apr. April I use a wormer/fluke combi only need something for adults, but what should I use at the beginning? I have both a triclabendazole based one, and a closantel based one, so I’m not using the same active ingredient. Do both of these kill down to the same age? I can see they both say immature and mature, but the closantel based one specifies kill rates of immature broken down into weeks so didn’t know if this one was more effective? At the beginning I’m assuming I really need the one that kills down to the youngest age.
