The best thing you can do is knock them into a dish of soapy water every day. They are on the wing for a short time and will not be on your plants all summer. The worst option is a device that attracts them to its container and then they meet their demise. That will bring them from miles around to your yard. Any kind of residual spray will harm the beneficials.
