Most offices, housing societies and restaurants have a pest control annual maintenance contract (AMC). Many of them still have cockroaches in the pantry and rats in the parking. The contract is being honoured, with a technician arriving every quarter, but the pests remain. Here's why that happens and how to fix it.
Why AMCs fail
- Visits follow the calendar, not the pests. A quarterly spray happens whether there is a problem or not, and a problem that starts the week after a visit gets ignored for three months.
- Spray and go. Spraying is quick and visible, but it doesn't reach cockroaches hiding in hinges and shafts. It can also drive them away from baits that would have worked.
- No inspection. Without looking for droppings, entry points and harbourage, the technician treats where it is convenient, not where the pests are.
- The source is never treated. Cockroaches come up from drains and shafts; rats come in from the compound. Treating only the pantry deals with the symptom.
- Nobody fixes the conditions. Food left out, overflowing bins, gaps around pipes and leaking taps keep bringing pests back, and the service report never mentions them.
- Records without information. A certificate says a visit happened, but not what was found, so nobody can tell whether things are getting better or worse.
- Wrong timing. Termite work done after the monsoon, or mosquito control that is only fogging, misses the moment when it would matter.
What an integrated pest management programme does differently
Integrated pest management (IPM) treats pest control as a process rather than a spray schedule:
- A baseline inspection and site map showing risk areas, entry points and where monitoring stations are placed.
- Monitoring with numbered bait stations and inspection points, checked and recorded every visit.
- Targeted treatment: gel baits for cockroaches, bait stations and traps for rodents, larviciding for mosquitoes, barrier treatment for termites.
- Proofing and housekeeping recommendations in every report, with a clear note of who is responsible for each.
- Trend tracking so you can see activity falling, or spot a new problem early.
- A seasonal plan: termite and rodent work before the monsoon, intensive mosquito control from June to October.
- Response between visits when your staff report activity.
Eight questions to ask about your current contract
- Does the technician inspect before treating, or start spraying straight away?
- Do you receive a report of what was found, not just a certificate?
- Are drains, shafts, garbage areas and the compound included, or only indoor areas?
- Are rodent bait stations numbered, and is each one's activity recorded?
- Do reports include proofing and housekeeping recommendations?
- What happens if you report pests between visits, and how fast?
- Are products registered with the Central Insecticides Board, and are they named on the certificate?
- Is the schedule adjusted for the monsoon?
If the answer to most of these is no, the contract is buying visits, not results.
How to write a better contract
- Scope by area and pest: which zones, which pests, which methods.
- Frequency by risk: monthly for kitchens and food areas, quarterly for offices, extra monsoon visits for mosquitoes.
- Response time for complaints between visits.
- Reporting: findings, actions, recommendations and trends after every visit, plus a treatment certificate.
- Outcomes: agreed measures such as the number of complaints and monitoring station activity, reviewed every quarter.
Your side of the deal
Even the best programme fails if conditions don't change. Assign someone to act on the recommendations: seal the gaps, fix the leaks, empty the bins at night, and keep stores off the floor. Pest control works best as a partnership between the provider and the people who run the site every day.
