Common Garden Pests in Colorado (and How to Manage Them)
APHIDS
These tiny sap-sucking insects come in all different colors, including light green, white, black, brown, gray, and yellow. Their soft, pear-shaped bodies can appear waxy or woolly. With their long antennae, these creatures would be adorable — if they weren’t so destructive. Aphids multiply quickly, and when large clusters of them inject their toxic saliva into plants, you’ll see leaves curling or turning yellow. You also leave a sticky “honeydew” substance on your plants, which can attract other insects, such as ants.
How to get rid of them
-First, try wiping off the affected leaves. If you have an infestation, try spraying the leaves with a mixture of water and dish soap. You may need to re-treat the leaves every few days for a couple of weeks.
-Lady beetles (ladybugs) love to eat aphids, so buy a colony, either online or at your local nursery and release them into your garden.
-Plant some catnip near your affected plants, as the herb repels aphids. Keep in mind. You may be overrun with neighborhood cats.
