Why do rats love your car’s engine area?

Rats being nocturnal animals come out from their day dens (sewers & gutters) at night in search of food. Your vehicle’s engine area is a safe 2nd home to eat food in peace – away from cats/dogs. Post dinner they have a necessary teething need to sharpen the insides of their front incisor teeth. Failing which can be life threatening, because their incisors grow at a rate of about 3 inches annually. The near endless supply of cables & wire under the hood ensures they have a juicy chew all night. Your car even has essential and clean water supply in the wiper spray ducts.

It’s tough to get rid of rats

Research shows rats depending on their species, share around 92% to 95% of their working DNA with us, humans. They are very intelligent and extremely territorial animals. No wonder, rats are one of the toughest pest to get rid of.
