An air puffer (the kind used to clean lenses) and a quick once-over with isopropyl alcohol wipes would probably be more than enough. I’d hope that your camera wouldn’t be a strong source for hitchhikers: it’s made of delightfully smooth and synthetic materials, and you’re hopefully not leaving it lying on the ground or anything.
Feel free to point at this post and laugh when I lose all of my plants to spider mites.
