How often do you need to apply it?

Same here . I still saw rodent droppings in my engine bay. Today was supposed to be the second day for re-application. I’d say this product doesn’t really work.

I do not see a listing of ingredients in the description. Can someone please tell me what the ingredients are?

The exact ingredients on the bottle are: pure peppermint essential oil, water and other non toxic emulsifiers. So far it has worked great for us and we also had a minor peppermint oil fragrance in the car. It does not last and we spray the motor weekly. Before this product we have $10,000 worth of wire damage to our Prius. You'd think that Toyota would get it not to use a soy based product, but they apparently don't. Good luck it's a good product.

What's different between this and other versions like "insect and pest control"? i'm going to assume that it's just marketing, which is fine.

Insect and pest control?? Like Raid, etc. This is designed for inside your car engine. Will not harm wires, etc., that squir.,mice and other critters like to chew on.

Is this good for roaches

It’s highly unlikely to have any affect on roaches. Rodents find the scent repulsive.
