these dont require spraying your plants, just vigilance, and personally id reccomend that first, unless you already have a spray regiment going.
And yea there are traps
If you grab the stalk down low and shake they fall off and you can stomp em, usually only lose 1 or 2 to fly aways
Problems only come i they build in numbers on or near by and are done trying to hump each other. If problems come from them though, it’s like a damn locust plague, ive had blackberry bushes mauled over single weekends. Like only skeleton remains mauled. You gotta be real lazy and unobservant to let that happen though, tbh. If there are no larger plants near by though, if unchecked they have a tendency to build up on a larger plant. A larger plant/bush/shrub surrounded by only shorter mowed grass becomes a lighthouse to them basically. It stands out to them on their flight paths as a source of food, and a likely place to find a mate.
