Four-lined plant bugs damage many species of herbaceous and woody plants, causing immediate damage, which may be severe in areas where bug populations are dense.

Overwintered eggs, inserted into woody plant tissues, hatch in spring. Nymphs can develop on many species of plants. More than 250 species in 57 families have been reported as hosts, but the bugs seem to prefer certain species in the mint family (Labiatae), nightshade family (Solonaceae), and the aster family (Asteraceae).

The bugs can cause considerable damage to a number of cultivated plant species. In the herb garden, peppermint, spearmint, sage, marjoram, lavender, and hyssop are consistently damaged.

In the flower garden; ageratum, coreopsis, dahlia, chrysanthemum, shasta daisy, gaillardia, and wormwood are damaged.

In the vegetable garden; parsnips can be seriously damaged, and cucumbers, lettuce, peas, potatoes, radishes, and squash are also attacked.

The form of the feeding damage varies with leaf shape, texture, pubescence, and venation. Leaves usually are peppered with small, depressed, round or irregular spots that may become transparent. Plants show symptoms of feeding damage as soon as the bugs’ stylets enter their tissues. The tissues clear immediately, beginning at the point of penetration and radiating out to from a roughly circular spot about 2 mm in diameter.

There is one generation per year.

Four Lined Bugs are getting to be a bigger problem every year. They have all but decimated a large planting of perennial geranium by late June. They've eaten into mums, valerian, brunnera, salvias, even looks like they tried some sedums.

I never noticed this bug until about four years ago. The infestation is getting worse every year. I have the same problem with the plants listed, but they are also devouring my butterfly bushes. How can I control them? I try not to use chemicals, but these critters are quick!

This bug seems new to my area (Minnesota). Have never seen in before this year, and boy did it destroy my spring perennial garden.
It seems like it will eat nearly anything. I've never resorted to insecticide before, but it was that or raze the entire garden this year.
How upsetting!

These bugs have infested and destroyed chrysanthemums and mint as well as Chinese lanterns and anemones. I would really like advice on how to get rid of them because they seem to be getting thicker and hungrier each year.

Oh this guy is a bad one! I could have written each post here. I have taken photos and they are just as found here. They need to be stopped any suggestions? Seven does not hinder them what so ever!

As the 1st line of defense, handpick the Four-lined Plant Bug whenever possible. (I rarely see it.)

When needed, use Rotenone, a plant-derived insecticide, which is harmless to warm-blooded animals, but kills all insects, and harms fish.

We just found out that this is the bug that is destroying our orregano and is now moving to our mint and God forbid - our basil! We're going to try neem oil first - I read that worked for someone else.

Is it too late for "HELP"? This bug is everywhere on our property, perennial and vegetable garden. Leaves are curling and falling off by the minute and it's only June. (2009). Second question... anyone suspect this damage on their rose bush? I have a reference that says damage from Fourlined Plant bug can look like fungal damage if severe enough. 50% of Our Rose leaves are tissue paper thin, irregular big patchy brown and see-through as if all chlorophyll is gone. Set right next to cranesbill. ANY comments? I hesitate to post that photo until I know...

Found them last night in one corner of the garden, have to pull all trimmed damaged foliage out of the compost pile!
Will ditomasious earth kill the larve?

Have wreaked havoc on my perennials the past two seasons, but most plants seem to recover as the summer progresses. Nasty little things, quick and hard to catch. Hopefully this spring's cool weather will limit their numbers.
