“Aphids are really bad this year!” This is what we've been hearing on social media and from many home gardeners. Aphids can curl leaves, stunt plant growth, and make a mess by the sticky honeydew they exude. Some aphid species create galls which can also damage plants. Low to moderate aphid infestations usually don't damage plants but if you do have more aphids this year, there are many options for controlling them.
Aphids in landscapes and gardens can be managed by a number of different methods, including biological control. Biological control is when naturally occurring beneficial insects, mites, or other organisms (also called natural enemies) reduce a pest's abundance by eating or parasitizing them.

Why might you release spiders outside? Spiders are beneficial insects called natural enemies. They are predators that help control other pests and insect eggs.
Beneficial insects can provide a lot of support in the garden. Natural enemies, which include predators, parasites, and pathogens, reduce pest populations and can help prevent damage to plants. Pollinators such as honeybees, native bees, butterflies, beetles, and other insects are essential for many vegetables you may be growing.
You may not have noticed many of these parasites, pathogens, and predators that help control pests in the garden, but they are there! Lady beetles (ladybugs), lacewings, and predaceous ground beetles are some common predators that you may find in your garden.../h2>
For the last two years, UC IPM has shared an Easter egg photo quiz with insect and spider eggs and egg cases. In case you want to play again, this post is from our 2018 egg hunt and this post is our 2019 egg hunt.
This year, with everyone sheltering-in-place, we want you to hunt for insect eggs and share photos with UC IPM! As you are planting seeds, weeding, watering the plants, or out in nature, keep an eye out for eggs hiding in plain...
