Trying Aroma in my BH

Due to some many incident to my BH recently, decided to try out apply Aroma to my BH. I bought a new type of Aroma from a shop in Klang and sprayed the Aroma during last visit. I will update the progress after next visit.

Observe from the BH after applied the Aroma, look like the swiftlet enter the bird house and stay longer then before. The Aroma that I used is from Indonesia and claimed very effective in certain area, do hope the same for my BH.
