Car Engine Spray for Rats

Rats are a common problem for car owners, as they can chew on wires and other components, causing damage that can be expensive to repair. Car engine spray is a popular way to deter rats from entering your engine compartment, but is it effective?

Car engine spray typically contains a variety of ingredients, including peppermint oil, cayenne pepper, and capsaicin. These ingredients are all known to be irritating to rats, and when sprayed in the engine compartment, they can create an unpleasant environment that rats will avoid.

Is Car Engine Spray Effective?

There is no scientific consensus on the effectiveness of car engine spray. Some studies have shown that it can be effective in deterring rats, while other studies have found no effect. One study, published in the journal “Pest Management Science,” found that car engine spray was effective in reducing rat activity by 50%. However, another study, published in the journal “Applied Animal Behaviour Science,” found that car engine spray had no effect on rat activity.
