Not sure what you mean by the plastic clip, but by posting this you mean I shouldn't be looking for ways to seal the air intake? Which is kind of what I thought, and thought it odd that that is what my mechanic was seemingly implying...
You did not try the right trap. Look at this one from Home Depot Victor Smart-Kill Wifi Electronic Rat Trap-M2 - The Home Depot. Bait it with peanut butter and or chocolate.
Yeah -- me too (when the rats come for my Prius...)! Is there a "deluxe" video version so you can watch all the "action" live on your phone?!?
It's one of those clips, IIRC, unscrew anti-clockwise with a pozidrive, a few turns and then prise out.
Bummer. Look what happened to me over the winter. Had my first Wth moment - Varmit ate thru seat cover! | PriusChat Not good! I am trapping the varmints now.
