“Good guys or bad guys?” That’s the question that accompanied this photo of mystery insects that suddenly appeared on a rose bush in a Sacramento garden.
Definitely bad guys – and they’re beginning to pop up all over town, especially on tomatoes, soft fruit and roses. The reason? They love triple-digit heat.
Those are nymphs (babies) of the leaf-footed bug, a relative of stink bugs. They'll make holes through your roses (and lots of other things). They’re very bad on tomatoes and can be a pest on apricots and peaches. They also like pomegranates, almonds, pistachios, citrus and watermelons.
Most of their damage is cosmetic, but in big numbers they can be a real nuisance. They puncture the fruit’s skin and suck out its juices.
The good news: They can't fly and they're slow. When young, they stick together. They release a pheromone that keeps the developing bugs in a little pack. (The better to attack your plants.)
Here's what leaf-footed bugs look like as adults.

Like many stink bugs, they're resistant to any pesticides (unless it’s a direct hit). Because the young nymphs are wingless, their instinct is to jump down from wherever they’re dining and scramble for cover.
What to do? Under the plant, put a bucket or dishpan of water with a teaspoon of dish soap (to break the surface tension). Then, gently shake the bush, vine, branch or cane and knock the bugs into the water. (Often, they will just jump when they see your shadow.) They can't swim and they drown.
You also can blast the hell out of them with a hose (you’re watering the plants at the same time). Or you can just squish them, but wear gloves; they'll stain your hands (and they stink).

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
