Ha Ha LOL are there still people buying aroma? Snake oil. I guess drowning people will clutch at straws.

Best aroma is lots of bird shit......WET bird shit.

Best sound track for attracting birds? There isn't one. Some sounds work well in one district but cannot call birds in another. Try, test, to find a suitable sound. Beware of sound peddlers that add duress sound somewhere in the track. It'll work well to attract birds for the wrong reason.

Don't be fooled, there are many quacks around.

Post your building plans and pictures of your surroundings, might be able to suggest a few ideas. Incl how the various breakins were done.

WW Pahang will fall to PH next week.

Many swiftlet 'farmers' make money from selling 'miracle' sounds and not from their nests. Not all sounds work, some work better than others and some work for a short while only. A sound that works for your neighbour might not work for you.

Where is your location, maybe some locals ranchers can help.

Simple criteria. The sound attracts birds. It should attract passing birds and entice them to enter the new birdhouse to explore and hopefully stay.

Many sounds attract birds. Some more so than others. eg a sound of birds under duress will darken the sky with them as they are curious to see what is causing the duress. This sound will not entice birds to stay in your farm.

Good sounds attractive to these birds are usually mating sounds. This brings the young birds to discover the new nesting site and hopefully will be happy to stay.

Wow been a long time since I last looked here.

Spray Fendona all over including the nesting planks, tweeters, and unharvested nests. This will kill all the mites as well as when the mite eggs hatch. If you don't do this the mites will continue to breed.

Fendona won't kill any of the birds, even the babies in the nests. The level of toxicity is very low for humans and practically none after the nests are processed. That's why is approved for use in kitchens, restaurants and inside homes for bedding etc.
