When you see spiders in your garden, you may wonder if they can hurt you or your pets. The good news is, most spiders are not likely to bite or cause lasting harm if they do. Plus, they provide natural pest control! Here are a few spiders commonly found in gardens and landscapes:

Crab or flower spiders look like tiny crabs. They use their enlarged front legs to stalk or hunt their prey.
The red imported fire ant, or RIFA for short, is no ordinary red ant. This invasive pest lives up to its name, delivering a sting that causes a burning sensation when its venom is injected into the skin.

This is followed by the formation of a white pustule, which can take several weeks to disappear. If not kept clean, the pustules can become infected and may leave permanent scarring. A small...
As part of our coverage of California Invasive Species Action Week, today we focus on a pair of invasive species that “work” together: an insect called the Asian citrus psyllid and the plant disease it can spread, huanglongbing.
Our long-time readers will know that we write about these pests quite a bit. That's because this pest pair has the potential of causing profound economic harm to the California citrus industry. So please read on and found out what you can do to help.

Watch out for some of these pests and diseases:
Apricot trees need to be pruned in summer instead of fall to avoid a disease called Eutypa dieback. It causes limbs and twigs to wilt suddenly and die.
