Aphids are one of gardeners’ most hated pests. They’re incredibly prolific, seemingly popping up overnight to take down your favorite veggies.

"Aphids are just experts at reproducing," said Ian Grettenberger an entomologist at the University of California, Davis. "Given the right conditions, they can multiply really quickly and get out of control.

For most of the year female aphids giving live birth to clones that are themselves already pregnant. That means that most of the time, all of the aphids you see in your garden are pregnant females.

When their population gets big enough and the plant they’re on starts to wane, aphids start giving birth to a new type of winged clones called alates. Amazingly, the alates are genetically identical to their wingless mothers. The alates take to the air to find new plants to colonize.

What do aphids eat?
Aphids use their pointy stylet to pierce plant leaves and such out the sugary sap. Usually, plants can handle a light infestation, but aphids reproduce quickly. Heavily infested leaves yellow and wither. Aphids can also carry viruses that they spread between the different plants they feed on.

How do aphids spread?
Aphids give birth to winged clones called alates that fly from plant to plant. Since aphids can clone themselves, it only takes one aphid to infiltrate your garden and start causing trouble.

How do I get rid of aphids?
Some gardeners use oils and pesticide sprays to get rid of aphids but it’s very challenging to get every last one of them. You can purchase predators like lacewing larvae to hunt and eat aphids. You can also purchase parasitoid wasps that lay their eggs in aphids, killing them.
