naphthalene inside engine bay

I cannot see the pics very well.
Pure naphthalene is moth balls..solid at room temp.. and a minor component of gasoline
Has some tox issues and is strong aromatic solvent may attack plastics.
Never heard it repells mice

 

That looks terrible from chemical safety perspective, to be honest.

 

Peppermint oil.

SM-G900V ?

 

As long as you don't spray in one area constantly it should be fine. Start the car after and let it warmup and burn off some of the water. Don't soak the inverter, fuse box, or anything electrical. Don't spray with engine running as you risk sucking water through the intake.

No need to panic.
It's a volatile material so it should evaporate, and it is not highly toxic.
But you don't want to get into your eyes.
It melts to liquid at about 175F
I think if you hosed off with water, or brushed some with a broom, and let the rest evaporate, you'd be OK.
The problem with dissolving it, is then in liquid form it might eat into plastics.

 

Should be. Then get some pure peppermint oil, soak some cotton balls in it and place them in a sock or panty hose and tie that under the hood somewhere it won't interfere with vehicle operation. Should rid you of rodents.

Just try not to get it on your skin or eyes, and do not breathe in the dust.

 

..probably a good trip down the highway would evaporate a bunch just due to the air movement

put a fan over night until it goes away

 

Well, yes but, at your own risk. I have on my previous Gen 2 and Gen 3 cars. Never had an issue. Don't soak it and don't spray with direct high pressure.

I would use a damp cloth.
