Yeah, but EMPs would only affect robots. Disruptors shut down electrics AND knock out, paralyze, nauseate, confuse, blind, demoralize and a bunch of other fun but non-lethal effects.There are also disruptors to deal with mechanical objects, but these won't affect electrics and vice versa.

It apears the Ka have found their nemesis. The organic will be avoided at all costs until more data is collected
Direct confrontation will certainly affect the Ka in a negative capacity. Perhaps basic battery bombs will be used or dormant ship tactics to gather said data.
