How to Manage Pests
UC Pest Management Guidelines
Plant bugs are sucking insects. The anterior portion of their forewings is leathery and the posterior portion is membranous. The false chinch bug and weed bug are occasional nuisance pests. Both species are a pale gray color as adults and nymphs and feed on weedy hosts; the false chinch bug is just under 0.25 inch, while the weed bug is just over 0.25 inch. When winter rains permit heavy growth of vegetation, these bug populations build up to large numbers. Later, as the vegetation dries down, the bugs migrate from the wild hosts and invade residential areas, including lawns and houses.
White-marked fleahopper adults are about 0.125 inch long, blackish or grayish, and have white markings on the wings, which are folded over the back. Their long antennae, white markings, larger size, and sucking mouthparts distinguish them from flea beetles. Fleahoppers can be observed by running your hand over the turfgrass or dichondra lawn. If they are present, they will hop about; some will land on the hand or sidewalks where they can be observed more readily.
All turfgrass species and dichondra.
Outbreaks of plant bugs are not common, but when they do occur, they can be damaging to turfgrass. All species of plant bugs feed via sucking mouthparts, so damaging populations can be expected to cause yellowing and stunting of the turf. Turfgrass is sometimes treated to prevent false chinch bugs and weed bugs from migrating into dwellings.
Treat for plant bugs if populations are high enough that damage may occur.
