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.

Mouse/Rat repellent. I needed something to use around my car because who wants to have their car engine sputter and lose power when driving? Apparently, a mouse and or a rat of some sort, crawled into my engine area and chewed my wires in the engine area. I was made aware of this product through our car service center. So far, it has worked. This will save you grief in the long run and bucks at your expense to get your car fixed, not to mention towing and rental car. This was an expensive fix. However, if you are a mechanic yourself it wouldn't cost you that much. Invest in this product!

Muy buen producto. Desde la primera aplicación, dejé de ver rastros de roedores en el motor. Para Ratas o ratones, muy efectivo! Ojo, para ardillas no está especificado, considérenlo antes de aplicarlo.

Tenia mis dudas, todas las noches el cacomixtle se metia mis carros, no importaba si era nuevo o viejo. Al inicio trate de ponerle una casita para alejarlos pero no funciono. Encontre este producto y funciono perfectamente ya no se mete a mis carros, aparte que deja un olor a menta, una botella dura aprox dos meses, ya es mi compra mensual este producto
