Guys just buy a Hit the red one .Spray properly in infected area. Be careful use a mask. After spray close your car door with glasses rolled up. It wil take hardly 10 minutes to kill every insect in the car. Dont use your car for next 24 hours. Clean the car and now spray a good air freshner. Purchase a good insecticide from an agriculture seed store and spray it on your parking place after every 4-5 days .
