How to Get Black Bugs Out of Raspberries

1). Identify the black bug on your raspberries. The most common type of Picnic Beetle is a small, black bug with four yellowish-orange spots on the back and is about a quarter-inch long. Overripe and decaying raspberries tend to attract the bug. The Picnic Beetle might destroy the healthy fruit once it is in the garden.
2). Pick ripe and damaged raspberries from the patch and place into a gallon bucket. To prevent further Picnic Beetles from entering and consuming the fruit, pick the ripe and damaged fruit on a regular basis. According to the University of Minnesota Extension, unlike most raspberry pests, Picnic Beetles reproduce outside of the patch and fly in when the berries are too ripe.
3). Handpick the remaining black bugs off of the raspberry bush and put them into the bucket. Bury the ripe and damaged raspberries, along with the bugs, to deter the black bugs from returning to your raspberry patch.
