Q

Treatment & prevention for Rhipicephalus spp?

A

parasiticides are effective. This is much easier to control than Amblyomma because Rhipicephalus spp is a 1 host tick.

If lactating dairy cattle, carbamates and organophosphates are applied as sprays or in backrubbers for the control of ticks

Rhipicephalus spp are REPORTABLE ON CATTLE!!! If you see them, submit them to a regulatory vet to determine if cattle need to be quarantined!
