I just came back from my hometown and help my parents with their bird house as well. They add another 2 humidifiers in the upper stair. Total up 4 humdifiers, 2 each room. But as usual, my parents didnt put humidifier in the downstair ( most populated area). Last few months were mating months? Because i saw alot of new swiftlets flying around. And manage to harvest more than usual (4.5kg). We were surprised because normally we harvest twice a month which total up around 1.5-2kg. I did count the bird nests too. I noticed the increment not so fast compared to last time. From august to december last year, increase from 1.3k to 1.7k nests. But as long there are increment, we will be happy. We are rural folks anyways except im studying at town right now. The bird shit seriously make me nearly fainted even i did wear my mask

. So i asked my mum, "ma, go buy oxygen tanks like diver use one", and she laughed.

Are the bird shit harmful?
So far i found few problems. The first problem with my BH is that there are lizards. Not sure got mouse or not. But i think my parents found few solutions for it. I will try to discuss with them more when i am on holiday which is next week. They operate the humidifer for 3 times a day. 45mins each time. Sometime im worried if it is too much or too little

. Should i get thermostat instead? And i told my mum to use fujibin humidifer for downstair one. Just use one since the fujibin humidifier can cover a large area.
From my experience,
1. I have in thousands of nests BH regularly and the smell is serious but I am still alive and well and worst, I don't wear any mask as I can't breath thru mask and feel very uncomfortable with them. That's proved that it's harmless but then, if you not healthy, you may faint so try to clean your BH more regularly to prevent the ammonia from BS as according to doctors, it's dangerous and bad for health to inhale too much of ammonia gasses. Oyes, in my BH, I would aften have s closed window in every floor so that when I am in the BH, I would open the window and let fresh air in.
2. By the way you describe the situation, you must have wet floor to create so much of gasses or otherwise you must have thousands of birds to produce similar effect.
3. Comparison with last year or any year is wrong as different time, different climate and almost everything can make a difference and the worst is the way you manage your BH. As I always mentioned, when the good is going, maintain the way and don't be stupid to follow blindly to any consultant's advice....not even mine!!!!
4. I have lizard problem, too but then, we manage to kill them so we need not use any chemical but I do heat that there is lizard stick and food to eliminate the pest...
5. Ultrasonic Humidifier has its problem like you need very clean water and maintenance is rather high. Break down more regularly but I do like the mist and not wet floor...feeling like you are in heaven ..hahaha. Furthermore, birds don't mind the ultrasound create by the UH.....honest
remarks by me!!!
6. As for the danger of UH posted by CoolAndy, you need to check it out. Best of luck to you , my friend.

i think they are using some sort of chemical product/potion or whatever it is. Im not really sure yet but they told me the liquid thing actually is to prevent ants from entering the BH. Odourless chemical i believe. Lets see how effective it is when i go back next week.
Just to share some of my BH pics: note the 2nd picture. The last plank is too close to the wall. That time constructor

For a new BH, in my opinion, it is best not to use any chemical even that the products seller may tell you that it's safe cos the seller may not know anything about BH or just pure good salesmanship. In the end, you lose or win but he still gain no matter what the outcome so beware....
Last Friday, I just went to visit 2 3S BHs (25x80) for sales @ RM520 K each with an acre of wet land @ Pekan. Over 6 months and after viewing the BH, I feel sad for the owners as the conditions and methods are not to my expectation of BH sanctuary specifications. On the way to the location, over 50 BHs can be seen by the lane and what about the interior which is not visible to my eyes......I went into the BH, the smell is not what I expect a BH should smell and too many even to comment.
If he is selling @ cost, then I will buy and try my luck but at the price quoted then I need to consider or recommending them to my friends to invest there as we will need to spend alot of money and also the location is too far and also at that area over 10 BHs, all not succefull.....so the competition to lure swiftlets is very high and difficult. Area suitable but everybody fighting for survival and that why I am against Eco Park concept in the first place for if too many BHs at ond location it's itself create a difficulty to gather enough birds to sustain and generate enough income to justified investment. The older BHs at the location will be better as they have an early start in the race.
Any buyers here interested, I can introduce the broker to you without any commission or kickback to me. There are many sellers @ Pekan and even failed BHs, some sellers are offering high prices for their BHs. One BH (3years) with just 200 nests is asking for 1.2M.
So, before you jump the Gun, make sure that your money is well invested at good location and with good consultant or contractor. Even if you failed, then you will get back all your money invested but don't expect to make alot of money for a failed BH unless the new intended buyer is a Fool.
Above is just my opinions on the matter concerning BH investment.
