Termites (coptotermes, schedorhinotermes, nasutitermes) are endemic across Sydney, especially the Hills District, Inner West, Northern Beaches, and Hornsby Shire. AS 3660.1-2014 covers pre-construction barriers (physical stainless-steel mesh, graded-stone, or chemical soil treatment) mandatory on all new builds and major renovations. AS 3660.2-2017 covers existing-building treatment via chemical baiting, soil injection, or physical retrofit barriers.

Pest treatment operators must be licensed under the NSW Pesticides Regulation 2017. Insurance-backed warranties (6 years typical) are industry standard and transfer to buyers at sale. Annual inspection is the recommended maintenance regime.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
