Spraying a shop is a licensed vector-control operator

Last updated 31 October 2026.

A shop with cockroaches behind the fridge, rats at the loading door, or larvae in a blocked roof gutter is often offered a “spray” by whoever is already cleaning or fitting the unit. NEA’s circular on the Control of Vectors and Pesticides Act says only a licensed vector control operator may advertise or provide treatment, control or elimination of mosquitoes, flies, cockroaches, rats and rat fleas, wherever the work is done. The pesticides are often restricted. The circular tells the public to use a licensed operator, to ask for the licence, to check that the person applying the product is a licensed technician or a certified worker, and to check that the product has an NEA registration mark. A cleaning company, a handyman and a car-detailer are named in that circular as examples of businesses that still need the licence if they advertise cockroach treatment.

Homey Furnishing Pte. Ltd. is not a vector control operator. The sealing page already says so. This guide does not add a spray price, a fogging price, or a bait-station price. If the photo is an active infestation, book a licensed operator. If the photo is a gap we already price, use that band. A shop door sweep, a mesh over a vent, and a silicone line at a pipe are quote on inspection unless they are the chute surround or the ledge net already printed.

People ask whether pest control is worth the cost, how to start a pest-control business, and what the mosquito penalty is. Worth is your infestation, not a slogan. Starting a business is NEA’s registration, not a page we sell. The penalty that NEA’s dengue-inspection page states for premises is a fine of up to S$5,000, or imprisonment up to 3 months, or both, under the Act. The composition sums NEA published in July 2020 for households, starting at S$200, are that household schedule. Construction sites on the same release were a different and larger schedule. Do not paste the household S$200 onto a shop and call it the fine. If NEA writes to you, the notice states the sum.

Curtains, blinds and roller shades are not part of this booking. A roller shutter is a different product and stays on the shutter page.

A licensed operator displays the certificate at the principal place of business and at every other place they trade, keeps a technician with the experience NEA requires, and does not hand restricted products to an unlicensed firm. GoBusiness lists the operator certificate. The fee stated there is S$90 for applications and renewals submitted before 1 April 2026, and S$99 from that date. That is the registration fee. It is not the price of treating your shop. Technicians and workers have their own fees on the same NEA pages. We do not quote them as our charges.

Sealing is physical. The chute page prices an under-sink surround at S$120 to S$220 when it is booked with a hopper, and the hopper itself at S$188 to S$280. Ledge netting is S$350 to S$580. Those rows close a path. They do not kill an infestation that is already inside the wall. The blog on sealing versus pest control is the longer version of that distinction for a home. A shop is the same distinction with a commercial door: a brush that does not meet the floor is a gap, and the brush is quote on inspection. A brush that stops a fire door closing is the wrong brush. The door still has to shut.

Mosquitoes in a shop are usually water. A clogged gutter, a tray under an aircon, a bucket in the store, an open grease-trap lid that holds water. Emptying water and screening a vent are housekeeping and, where we have a band, a sealing visit. Fogging the shop during trading hours is the operator’s method, with NEA’s conditions on the operator: notification before fogging, PPE, and the product mixed to the label. We do not fog. We also do not tell you to pour the larvae away if an NEA officer is sampling them. NEA’s inspection page says the officer shows you the habitat and takes the sample. Do not tip it out.

Send the evidence: droppings, a smear photo of a cockroach, or a tray of water. Say whether you want a gap closed or an infestation treated. If it is treatment, we will say to use a licensed operator and we will not price it. If it is the chute or the ledge, use those rows. If it is a shop door, expect quote on inspection.

Do not ask for the treatment to be hidden inside a cleaning contract or a fit-out. The circular is written for that disguise.

Treatment is licensed. A gap is only priced when a row exists.

Questions a shop should ask

Ask for the licence before you ask for the price.

1. Is this treatment, or a gap?
2. Is the operator’s certificate current, and is the person on site a technician or a certified worker?
3. Is the product NEA-registered?
4. Will the fire door still close after any seal is fitted?
5. Where is the water, if the complaint is mosquitoes?
6. Are you being offered a spray inside a cleaning or handyman invoice?
7. Is the figure a household composition fine pasted onto a shop?
8. Do you want us to name a spray price? We will not.

The licence does not change. Who owns the corridor does.

NEA’s operator page says a new operator needs an ACRA registration and at least one dedicated technician with three consecutive years of recent vector-control experience, and pays the registration fee. The certificate is displayed. It is not transferable. Fogging is notified to NEA, with more notice before a weekend. None of that is a menu for treating one cafe. If you are hiring, ask to see the certificate and the technician’s card, then ask what they will use and where they will not spray. If you are trying to start the business, the GoBusiness page is the application. This site does not coach that application.

Food shops have a second constraint. NEA’s environmental-health code and SFA’s checklist want surfaces that can be cleaned and pests kept out by the way the premises are built: doors that close, screens, no gaps. A spray does not repair a door that stands open onto a bin point. The door closer page is the closer. The sealing, if it matches a row, is the gap. The operator is the infestation. Three invoices, three jobs.

“Is pest control worth the cost?” is worth it when you can see the infestation or NEA has written to you. It is not worth a monthly fog that leaves the bucket of water in the store. Spend the first dollar on the water and the gap. Spend the licensed visit on what is still alive.

NEA’s circular, the operator page and the GoBusiness fee are the licensing sources. The dengue inspection page is the source for the premises penalty of up to S$5,000 or 3 months, or both. The July 2020 household composition schedule is cited only as that schedule, not as a shop fine.

We are not the operator. Chemical treatment stays off our invoice. A fire door, an exit sign and a food-preparation surface are not places to experiment with a seal or a spray.

How you're charged

A job that already has a sentence on HomeySG uses that sentence. The hour is not added on top of a band unless the written scope says so. There is no fuel surcharge and no published night premium except the mall overnight row. A shop does not inherit a flat’s price just because the fitting looks similar.

Only the chute, hopper and ledge-net rows are priced. A shop sweep, a mesh, and every pesticide are quote on inspection or not offered. NEA’s S$99 is their registration fee.

Ways to keep the bill smaller

• Tip out standing water before you pay for a fog.
• Close the priced gap once. A monthly fog through the same hole is the expensive loop.
• Hire the operator for the infestation only. Do not hide it in a cleaning contract.
• Check the licence before the visit. An unlicensed spray is not a bargain.

Sealing rows only. The registration fee is NEA’s, listed so it is not mistaken for a treatment.

Anything not in that table is quote on inspection.

WhatsApp the photos to +65 8561 0630. The reply uses a band already printed on HomeySG, or it says quote on inspection.
