They have probably been back for a week or so because it has been raining so much I haven't been scouting out in the herb garden. The four-lined plant bugs are back for another season. The Herbal Husband is just devastated to see them. They are trouble, but I learned as a master gardener that a lot of bugs can only be managed especially if you do not want to spray toxic chemicals. Lots of the organic solutions are just as toxic. So it is better to just try and squish the nymphs and adults. They are true bugs which means just two stages. The nymphs are red and the adults are a yellow green color with four black lines. Last season I even saw the nymphs morphing into the adults. The good news is is there is only one generation a season and the damage will not kill your herbs only disfigure them. The herbs put on new growth to cover over the damage. I did a guest post about on The Herb Companion website. Here is the link called
Herbal Pests: The Four-Lined Plant Bug.
This is damage on oregano. The nymphs do not fly. I was squishing nymphs yesterday. They can be very quick as are the adults. The adults fly and they are quick and drop to the ground if they feel under attack. I just love to put on my Mud gloves and squish away. The top photo shows the nymphs on sage. They love members of the mint family, four-sided stemmed plants. All your favorite herbs. Click on the link above to get a partial list from my post last year. The plants all survive the damage. I have never lost a plant to four-lined plant bug damage. Hope if you have this insect your damage will be relatively light. They should be gone by the end of June at least in western Pennsylvania.
