This concerns an invasive mosquito (Aedes aegypti) that carries dengue/yellow fever/zika and more. Males were raised with a mutation that, passed on to offspring, kills females before reach adulthood (and have grandchildren).
They released this on 1 hectacre of land, the genes functioned as expected, and the genes didn't travel more than 400m (affected mosquitoes have a sort of fluorescence under the right light). Probably also as expected, the genes disappeared after a year (a few generations). My guess is that mostly happened from neighboring unmodified Aedes aegypti mosquitoes genes coming over to replace the modified ones.
AFAIK it'd take a monumental effort to wipe out a species this way, but suppressing or near-eliminating a population in a place you can isolate from non-modified aegypti sounds possible, particularly if you do other suppressive efforts.
