Sugar ants are a common problem in cars. They can be a nuisance, as they will often build nests in areas where food is stored or where people sit. There are several ways to get rid of sugar ants in a car. One way is to use a vacuum cleaner with the hose attachment. Make sure to turn the vacuum cleaner off before reaching into the car, as the noise may scare the ants away. Another method is to pour boiling water into the car and wait five minutes. The heat will kill any sugar ants that are inside the car. ..
