Lindsey, I love that trap!! Put it under wherever your HOSP is perching; near your feeders, next to a fence, near favorite shrubs etc. It works better when you have a decoy in it. Are you using millet/mixed seed to trap. They prefer white millet. But others have luck with bread,popcorn, etc. Sprinkle seed on liberally on the bait area #3 and then on the landing pad #3 and #6 area. Also sprinkle a little on the ground around the trap to first get them interested. So, like the others I would recommend that you purchase a cheap box ($9.99 at Lowes) and put a Van Ert trap in it. That’s how you get your decoy for your repeater trap. Your bluebirds will be interested in it though so set your timer and check on it every couple of hours. Never leave the house with it set.
