Which of these do I need? Start with where your house is stuck.

Birds come to play every day, but will not nest?

• At night you hear bird calls inside. In the morning there are hardly any nests on the planks
• The identical house next door has birds settling. Yours only get a look around
• Birds do come in, but for months the nest count has not moved

Birds that get in but will not stay are often missing one thing: a scent that says other birds live here. This group has only one product. You just need the right one for a new house or an old one.

This is a start, not the finish. Once you have used it and see a few more birds, that is when we can really help: send us a video of the inside of your house and we will look at it for free: how much more this house can grow, and where it gets stuck next.

Mouldy planks, an ageing house?

• The nesting planks have not been cleaned in three years or more, with white powder or black spots
• There is a stale, mouldy smell inside
• The house used to grow well. In the last few years it has slowed, or even dropped

Ageing is one of the most common roots of falling production, and the planks are the part of it you can deal with today, no walls to break, no structure to change. One more thing to know: by the time you can see mould, it has already been growing for a while.

Meranti+ Nesting Plank Enhancer

Meranti is a wood. Meranti+ is what looks after planks made of it.

People often think we are selling timber. We are not. It is not a scent for attracting birds either. It is for the planks: it prevents mould and removes odour, and you spray it on without climbing up to wipe each plank. Spraying new planks before they go up costs far less than rescuing them later.

Clean planks are what let the bird count grow. We needed this product ourselves first: the planks in our founder's father's house were all mouldy, nobody could give an answer, so we had a factory make a version just for swiftlet houses.

Spraying pesticide on the same day? The order matters.

Chalcid, Fendona and that class are high concentration pesticides. They must not go on the planks.

Why that order: with Meranti+ on the planks, the pests can no longer settle there and try to escape downward. You are waiting for them below, so one pass does it. If the infestation is bad enough that the planks themselves must be treated, you need a pesticide that is suitable for planks. Getting that wrong costs you a whole ceiling of planks, so ask us first.
One more thing: finish spraying before 1pm (12pm in East Malaysia), so the planks are dry before the birds come home.

Is it the planks, or the air? A video usually shows us. Send us a video of the inside of your house and we will look at it for free. In some cases you do not need to buy anything.

You keep changing the sound, and it is still wrong?

• Three external sounds later, the birds still circle outside the entrance hole
• Internal and external sound run off one machine, and no amount of tuning gets it right
• The more tweeters you add, the fewer birds you get

Sound is the last step, not the first. Check the flight path first, then the spots where the birds live, and only then the sound. Good sound in a house that does not flow does not just fail. It brings more birds in to take a look, find nowhere to stay, and not come back.

External and internal sound are two different jobs.

External sound is the signboard that calls passing swiftlets down. Internal sound is the food inside that gets the ones who came in to settle. However loud the signboard, if the food is bad the customer sits for a moment and leaves. So the two are handled separately, not covered with one sound.

3.0 for internal sound, PRO+ for external sound.

3.0 is the best sounding internal sound amplifier we have right now. PRO+ controls the low, mid and high of its two channels completely independently, one to the outer hole and one to the inner hole.

Good external sound makes the birds more willing to come and play. Good internal sound gets them to settle faster. Both matter, but which one your house needs first, and whether you need a new machine at all, comes after a diagnosis. Sometimes the answer is “the tuning is off, fix that, no new machine”, and then that is what we tell you.

3.0 or PRO+: how to choose

AU8 25P paper diaphragm tweeter

A 2×5 tweeter built around three old problems: leaking, muffled and distorted sound.

The back uses copper, not iron, so it does not rust in a swiftlet house. The back cover is thicker, so the sound does not leak out behind. We ran 8 kinds of tweeters side by side in our shop for three months, and the birds chose the 25P to nest on first.

You can check this yourself: look at where the nests are. Nests in front of a tweeter mean a good tweeter. Birds all nesting behind it usually means it is leaking sound.

Which tweeter goes in which section, and how they are arranged top to bottom, depends on your house. We go through it one by one in the masterclass. It does not fit on this page.

Which machine and which tweeter suit your house, we can only say after looking. Send us a video of the inside of your house, recording the internal sound first and then the external sound, and we will listen for free.
