Before jumping into any conclusion, I just wanted to say that these are just ideas and no guarantee that they will work.
Before you try please be careful not to harm you BH.
1) Throw Some Swiftlet Eggs On The Wall.
This is something that is possible. I was made to understand that many BH owners in the neighbouring countries are using this technique.
Just think of this. Most BH that were burgled, with all those eggs thrown on the floor, will be quickly filled with nests within a few short weeks. Most BH owner claimed that the nest number will increase by at least 10-20%. Do you know why? Because of those broken eggs !!!
In the neighbouring countries (cannot mentioned on my blog) this method have been practise for donkey years. What they did was to harvest those nest with eggs and immediately throw the eggs onto the walls. The effect was said to be very productive.
I do not recommend you use your BH eggs but try to buy them from the market and do the necessary. You need about 20 for one floor (20'X70'). If you cannot find them how about substitute the swiftlet eggs with burung puyuh bird egg?
Note: I do not guarantee anything but U might want to try.
2) Use Sea Cucumber laced with Ammonia Powder.
I received a call from a friend staying in JB.
"Harry I came to know that there is a very successful consultant based in Klang who use sea cucumber laced with ammonia powder. They put the dead sea cucumber in a container and laced it with ammonia."
Are U sure?
Hmm so so.
So if you want to try better think twice.
3) Ferment Those Birdshit !!!
This is something natural and original. Take about 5 kilos of fresh birdshit and mix them with tap water, about 5 liters or more.
Let the birdshit ferment for a few days and once ready filter for the water.
Now you are ready to splash to the BH wall. Before you do that it is recommended to mix with some fish oil.
Hmm ..... they sound very delicious like those tuak from the coconut tree.
Oh yeh please do not drink those birdshit water.....
All the above are for your knowledge and there is no proof that they can bring those birds into your BH.
If you choose to opt for any one or all Harry will not be responsible if anything should happened.
However if it works please let me know.
