If you have noticed spiders crawling in your car, it might be infested. The first thing I recommend you to do is to look closely for the nest since there is definitely the one. No need to hesitate! These tiny creatures, even non-venomous ones, may still be huge destruction for the driver and cause road accidents. You have to take a spray with natural oils since you don’t have much time to wait.
If you can use another car, just apply spray with chemicals. Repel it across the interior of the car. Wait for a week. You have to repeat the same procedure. I strongly recommend using odorless sprays or at least those which smell you like. Remember, this scent will be with you for the next couple of weeks.
