Thank you for contacting us about your raspberries. It is difficult to diagnose pest problems without a physical inspection. However, I suspect you may have seen the larvae of the spotted wing drosophila. These can be found in ripening fruit as opposed to other pests that occur in over-ripe fruit.

Here are some articles that may help you identify the pest and then take proper control measures. (Please note that the control options for home gardeners are more restrictive than for commercial growers.) If you choose to use a chemical control, spinosad is the active ingredient you should look for.
