If you’ve noticed yellow bugs on your car, then you’re not alone. With the arrival of spring, many small bugs of various colors become active.

And they show up in unlikely places and things, such as your car.

While they are harmless to humans and pets, they can be a nuisance to car owners, as their numbers can quickly multiply and leave unsightly marks on the car’s exterior.

In this guide, you’ll find out 7 types of tiny yellow bugs on cars, their behavior, and how to prevent them from congregating on your vehicle.

Let’s dive in.

Why Bugs Get Onto And Into Cars

Bugs get inside cars because they provide warm and sheltered environments that bugs can use for protection or nesting.

Bugs also find food sources in cars. The most common food sources that attract bugs to cars are food and beverage stains and food crumbs.

Bugs not only get inside cars. There are many bugs that can land on the car’s exteriors too.

It happens during the spring and summer months when most outdoor bugs and garden pests are active.

When the car is parked underneath trees or near dense vegetation, then the spillover of bugs and insects from them onto your car’s exterior is bound to happen.

Some bugs are attracted to the light-colored and reflective shiny surfaces of the cars. They misconstrue the car as potential mates or food sources!

The scents of the chemicals from the car, exhaust fumes, and fruity smell of some specific car odor eliminators attract bugs.

Wasps are one of the stinging flies that can get inside the cars attracted by the fruity smell.

These bugs are more visible on light-colored cars.

Globular springtails do not bite humans and are not known to transmit any diseases.

Carpet beetle larvae on car

Carpet beetles in cars are a common problem. These beetles lay their eggs inside the nooks and corners of your car.

Their larvae, which is a tiny brownish worm with yellow or tan stripes and hairy bristles, are damaging pests.

The larvae will feed on the fabric of the car’s interiors, leaving behind small holes and fecal deposits.

If your car’s interiors are made of leather, then it’s even better for the larvae.

It’s because the larvae feed on natural fibers like wool, silk, and leather.

Some carpet beetle larvae can crawl out of the car, in search of food, and appear on car’s exteriors.

On noticing the larvae, you must inspect your car.

Varroa mites are reddish-brown and can appear as tiny yellow dots.

Varroa mites have eight legs, and they have hairy bristles on their bodies. They’ll latch onto the honeybees to feed on their hemolymph (insect blood).

Varroa mites live in beehives. The infected honeybees introduce these parasites to their colonies.

Cars with bright colors, such as blue, purple, and yellow, can draw the honeybees. As these colors are often associated with flowers, your bright colored car can draw the honeybees.

Also, if there’s a fruity smell coming from your car, then it can draw the honeybees too, just like the way it attracts wasps.

As honeybees are active during the late spring and early summer, you may see varroa mites on your car during this period.

The varroa mites from the honeybees’ bodies can drop off on your car. And these varroa mites will appear as tiny yellowish or reddish dots crawling on the car.

The little yellow spots that you find on your car’s exteriors can be bug poop.

These fecal droppings appear as yellowish smears on the car’s exterior.

However, there are other things that can show up as yellow spots on cars –

Tree Sap: Many trees release their sap, which can drip onto cars parked underneath them. That leaves behind yellowish stains.

Pollen: During spring and summer many trees and flowers release pollens. These pollens can settle on the car, appearing as a layer of yellow dust.

Bird Droppings: Bird droppings can be yellowish in color and can cause damage to the car’s paint if left for too long.

Rust: If the car is getting rusty then the rust will appear as yellowish discoloration on the car.
