These bugs like it hot

Besides spider mites, one other pest apparently loves recent hot and smoky weather: Leaf-footed bugs. (They’re pretty crazy about tomatoes, too.)
Triple-digit heat has brought out an explosion of leaf-footed bugs in the greater Sacramento area. Right now, they’re scrambling around on ripe tomatoes and other fruit, sucking out juice. For example, dozens of young leaf-footed bugs were spotted in Midtown this weekend as multi generations feasted on the same tomato plants.
With distinctive leaf-shaped back legs, the leaf-footed bug is a close cousin to stink bugs – only bigger. Leaf-footed bugs often are an inch long and look like strange alien creatures. When young, they like to hang out in groups. Relatively slow to mature, they take six to eight weeks to reach adulthood. But once fully grown, they can stick around for months.
In the overall garden scheme of things, their damage is relatively minor. The leaf-footed bug stabs its long mouthparts into nice juicy fruit, flower buds, seeds and other favorite targets, then sucks out moisture. Usually, that results in only cosmetic damage; the fruit is still edible. But when their population grows like it is now, leaf-footed bugs become a bigger nuisance.
Three different species are native to California and they attack a wide range of crops and ornamental plants. The most common in Sacramento is Leptoglossus zonatus.
In home gardens, they primarily attack tomatoes, pomegranates and roses. They also have a huge appetite for almonds, pistachios, citrus and watermelon. But L. zonatus also will eat many different fruit, vegetables, nuts and flowers.

Leaf-footed bugs tend to congregate in weedy areas around vegetable or flower beds. (That’s also where they overwinter.) By removing weeds, you evict any leaf-footed bugs that may be sheltering in those plants, too.
The good news: Leaf-footed bugs can be easy to catch. No pesticides are necessary. The nymphs move slowly, stay in groups and can’t fly.
To remove them, gently shake the tomato plant or other host. Knock the nymphs off into a bucket of water with a teaspoon of liquid detergent. (The soap will keep the bugs from swimming to safety.) But wear gloves; if touched, these bugs will make your hands stink.
