How to identify Plant bugs

Damaged or discoloured leaves are some of the first signs of plant bug problems. While lesions will appear immediately following feeding, more serious plant damage will become noticeable within a few weeks. Heavy infestations may result in plants looking burned.

Habitat, Diet, and Life Cycle
These pests are found in every province in Canada and most of the United States and Mexico. They frequent areas with a high concentration of fruits and vegetables, and are likely to be found in gardens and orchards. Plant bugs overwinter in stream banks and rock piles, as well as under tree bark.
Most plant bugs eat flowers, weeds, and garden plants. They are particularly fond of beans, lettuce, peas, currants, and gooseberries. These bugs have also been known to eat azaleas, dogwoods, forsythia, and many other ornamental plants.
Plant bugs typically deposit one egg at a time onto leaves and produce two or three generations per year. Nymphs emerge after 7 to 10 days and are typically around 1 mm in length. The life cycle is completed within a month. Peak breeding season is in the summer.
