@douglasvb How often do you drive your Tacoma? That's the first deterrent - driving (or running the engine) every day.
Actually, I do it at least every other day along with the peppermint spray. I also have a LED bulb that automatically turns on when dark in a trouble light fixture I keep under the engine pointing up. I suspect running the engine is more effective than the spray or light. Tried traps, but after catching a native lizard, stopped.
I had $2K damage to a chewed wiring harness a couple years ago and was suddenly glad I had comprehensive insurance. No issue since then, knock on wood.
