Bait stations appears to be well designed for purpose, insecticide helpfully packaged to permit metering of small amounts as well as generous pours,, legally EPA labeled. But a 3 week delay due to an out-of-stock situation at the mfg/distributor meant that what was already a late season order was received after the local population of yellow jackets had all been trapped or died. Further, the shipment came without printed instructions of any kind, and the necessary support wires for hanging the stations were also missing. I expect it to perform as advertised, but will have to wait until next spring to verify that. The domyown web site does contain some instructions for use, and a video describing assembly and use, very helpful, but this crusty old customer who matured in the age of print-only always prefers print to refer to, you can't assemble the station while sitting at your computer.
