SIMPLE AND EFFECTIVE SWIFTLET HOUSE

This is one of my new design of swiftlet houses. It only used 3 units of MP3 players, 1 timer, 1 ton of timber plank, 500 pieces of timber corner edge, 40 pieces of indoor tweeters and 8 pieces of outdoor tweeters. I spray the aroma for BH twice a week. There are also some bird droppings mix with ammonia and water in a flat bucket. Finally, turn on the sound. .........................................
After 2 weeks time, a swiftlet is staying in this BH.
