We present a reinterpretation of CMS searches for type-III seesaw lepton triplets at the LHC, both for the normal and the inverse seesaw. We find that, in contrast with previous expectations, these searches in the trilepton final state have a good sensitivity to triplets with predominant coupling to the tau lepton. We also show that the limits resulting from direct searches can be neatly presented for arbitrary masses and general flavor mixings. Thus, it turns out that the common (and often unrealistic) simplifying assumptions about the flavor couplings of the triplets used by experimental collaborations to present their results are unnecessary and should be dropped.
