How Often Should You Replace Glueboards & UV Tubes?

An insect light trap only works if its consumables are fresh. Two parts wear out on a predictable cycle: the glueboard that holds the catch, and the UV tube that attracts insects in the first place. Replace them too late and your trap quietly stops performing — often without anyone noticing. Here is a practical replacement schedule for Malaysian commercial kitchens.

Why Replacement Schedules Matter

A glueboard loses its grip as it fills with insects and dust, and a UV tube fades long before it stops glowing. The catch rate drops gradually, so the trap looks like it is working when it is not. Auditors also expect to see a documented replacement routine, not guesswork.

How Often to Replace Glueboards

Glueboards should be changed on a regular cycle and sooner if they are visibly full or contaminated:

• Standard kitchens: every 4 weeks (monthly)

• High-traffic or high-fly areas such as bins and loading bays: every 2 to 3 weeks

• Immediately if a board is full, dusty, wet or greasy

• More often during monsoon and hot-season fly surges

In greasy environments, oil and airborne dust kill the adhesive faster than the catch does, so judge by condition as well as the calendar.

How Often to Replace UV Tubes

This is the step most businesses miss. A UV tube keeps lighting up well after its useful output has faded — but the wavelength that draws flies declines steadily over months.

• Replace UV tubes roughly every 12 months, even if they still light up

• Many operations change tubes at the start of the high-fly season to be at full strength when it matters most

• Replace any tube that flickers, dims or shows blackened ends right away

  
  

Keep It Simple With Maintenance Packs

The easiest way to stay on schedule is to keep consumables on the shelf before you need them. IKAWA Maintenance Packs bundle the correct glueboards and UV tubes for your units, so replacements are never delayed by a stock-out. Matching consumables to your specific model — IK-XEN18, IK-TAC700 or IK-TAC750 — keeps performance where it should be.

Build a Replacement Log

A short log turns maintenance into evidence for HACCP, GMP and MS 1480 audits. Record:

• Date of each glueboard change and which unit

• Date of each UV tube change

• Initials of the person who performed the change

• Any notes on heavy catches that might mean a hygiene issue nearby

A spike in catches is a useful early warning — it often points to a door left open, a drain issue or a bin that needs attention.

The Cost of Skipping Replacements

A faded UV tube or a clogged glueboard does not announce itself, because the trap still hums and glows. But catch rates quietly fall, flies build up, and the first real sign of trouble is often a customer complaint or a failed audit. The cost of a fresh tube or a pack of glueboards is tiny next to that risk, which is why a fixed schedule beats waiting for visible problems.

Think of consumables as the running cost of protection, like fuel for a vehicle. The trap is only as good as the parts inside it, and a disciplined replacement routine is what keeps your investment working day after day.
