Pest control in pharmaceutical industry: 5-zone device plan showing exterior bait stations, internal non-toxic monitors, insect light traps, air curtains and bird netting

SOP for Pest Control in Pharmaceutical Industry: Rodents, Insects & Birds

Short answer

Pest control in a pharmaceutical plant is a written GMP obligation. Revised Schedule M requires premises that keep out insects, birds and other animals, plus a written rodent and pest control procedure (Part I, clause 12.2.9)[1].

For pest control in pharmaceutical industry practice, the regulation sets the outcome but not the method. It says that no pest-control material may touch or contaminate the product (14.3, 16.5) and that SOPs and records must exist (17.3.10.1(f))[1]. It does not set a visit frequency, a bait-station spacing or, for most dosage forms, a device type. Those are your risk-based decisions, so this page marks each one as site policy.

  • Toxic rodenticide goes in locked exterior stations only. That is site policy, and it follows from 14.3 and 16.5.
  • Inside the building, use non-toxic monitors and glue-board insect light traps, and never place a trap above open product.
  • The contractor and the chemicals fall under the Insecticides Act, 1968. Each product must be registered (section 9), and commercial pest control operations need a licence (section 13)[2].
  • The evidence an inspector reads is the device map, the inspection records, the monthly trend review and the deviations raised from them.

What Schedule M requires for pest control in pharmaceutical industry

The table maps each clause that mentions pests in the notified Revised Schedule M (G.S.R. 922(E), 28 December 2023), with the international texts it mirrors. The right-hand column shows what each clause leaves to you. For the wider premises chapter, see the key points of Revised Schedule M.

On a phone, swipe the table sideways. Clause wording is condensed here; read the source before quoting it in an SOP.

What Schedule M does not say: checked in the full text

We searched every one of the 124 pages of the notified Schedule M reprint for specific words. Bait, glue, pest control operator, Insecticides Act and fortnight each return zero hits, and trap appears only in the drainage clause. The only devices it names are the fly catcher and air curtain (Part IX, 2.3) and insectocutors outside the airlock (Part X). So an SOP that cites a “Schedule M” bait-station spacing or visit frequency is quoting something else.

The Indian statutory layer that sits beside Schedule M

Schedule M does not cite the Insecticides Act, but the Act applies on its own terms to the chemicals and to the contractor. Every insecticide must be registered by the Registration Committee (section 9). Anyone undertaking commercial pest control operations with an insecticide needs a licence (section 13)[2]. Under rule 10(3A) of the Insecticides Rules, 1971, operations using aluminium phosphide, methyl bromide, ethylene dibromide or other notified fumigants need a separate pest-control-operator licence, with qualification and training conditions[7]. The published texts disagree on that licence’s form number, so check it with your state agriculture department.

The timing matters. As of October 2026, Revised Schedule M is being enforced, not waiting on a deadline. The extended deadline for MSMEs that applied passed on 31 December 2025, and in November 2025 CDSCO asked state regulators to plan inspections of manufacturing units[8]. Pest control is one of the easiest premises findings to evidence, and one of the easiest to get wrong on paper.

The 5-zone device plan for rodents, insects and birds

Because the regulation sets an outcome, the defensible way to write an SOP for pest control in pharmaceutical industry premises is by zone. Device type and chemical use change as you move from the fence line towards open product. The plan below is a schematic. Your own plan must be drawn on your site layout and approved by QA.

Pest control in pharmaceutical industry: 5-zone device plan showing exterior bait stations, internal non-toxic monitors, insect light traps, air curtains and bird netting
Figure 1. Schematic device plan for pest control in pharmaceutical industry premises. E = locked exterior bait station, M = non-toxic monitor, L = glue-board insect light trap. Toxic bait stays outside the building and no device sits inside the Grade A/B suite (both site policy). Device numbers match Annexure-I of the SOP below.
ZoneRodentsCrawling insectsFlying insectsBirds
Z1 Site perimeter and exteriorLocked, fixed, tamper-resistant bait stations with a registered rodenticideLicensed treatment of external surfaces per label; vegetation-free strip at wallsRemove breeding sites: drains, standing water, open wasteNetting or spikes on canopies and ledges
Z2 Building envelope and entriesProofing first: self-closing doors, sealed gaps and penetrations; monitors both sides of each doorSealed joints; monitors at thresholdsAir curtain or strip curtain; light trap inside, out of line of sight of the doorDock doors kept closed; strip curtains
Z3 Warehouse, corridors, utilities, canteenNon-toxic monitors along walls; pallets kept off wallsGlue-board monitors; spot treatment only under QA permitGlue-board light trapsAny bird inside is an action-level event
Z4 Production and QC (non-sterile)Monitors at airlocks only; no rodenticideMonitoring only; chemical treatment only at shutdown, with a permit and cleaning afterwardsLight trap outside the airlock, never above open productAction-level event; impact assessment of exposed product
Z5 Sterile / aseptic suiteNo devices inside Grade A/B; monitors at the outer change roomExclusion only; any find goes through the deviation routeLight trap in the corridor before the first change roomNot a credible route if the envelope is intact; any find triggers an integrity investigation

Every entry in this matrix is site policy built on Schedule M 12.2.9, 14.3 and 16.5 and on industry guidance. It is not compendial text.

Two placement rules come from industry guidance, not regulation, and are worth writing into the SOP as stated reasons. Light traps belong away from external doors and windows, so they do not draw insects into the building. And grid-type electric fly killers can throw insect fragments out of the unit, so their position must not put open product at risk[9]. The same guidance discourages “one per x metres” formulas for bait and monitor numbers: numbers should come from a risk assessment[9].

SOP for rodents, insects and birds control in production

This is the adaptable document. Every step is numbered so a deviation report can cite it. Each frequency and limit is badged by source: regulatory for statutory or GMP text, industry guidance for published good practice, and site policy for choices your QA must own.

SOP No.: QA/GEN/___ Version: 01 Effective: DD-MMM-YYYY Review: DD-MMM-YYYY Department: QA / Engineering Supersedes: ___

Pest control: prevention, monitoring and response for rodents, insects and birds

1. Purpose

To define how the site keeps rodents, insects and birds out of every zone and monitors for them. The procedure also covers the response when a pest is found, so that no pest and no pest-control material contaminates materials, equipment or product.

2. Scope

This SOP covers all buildings and the site perimeter: warehouse, production, QC laboratory, utilities, canteen and the outside of the sterile suite. It excludes fumigation and disinfection of the microbiology laboratory and cleanrooms, and routine cleaning and sanitisation, which each have their own SOP. Note that fumigation of a microbiology laboratory is a disinfection process, not pest control.

3. Responsibility

  • Pest control contractor (licensed): service visits, treatments from the approved list only, service reports.
  • Pest control coordinator (Engineering or Administration): escorts the contractor, carries out internal inspections, maintains the device map, raises proofing repairs.
  • Heads of Production, Warehouse and QC: keep their areas free of food and waste, and report sightings at once.
  • Quality Assurance: approves the contractor, the pesticide list and the device map; reviews records and trends monthly; manages deviations and CAPA.
  • Head QA: approves this SOP and its periodic review.

4. Definitions

  • Bait station (E): a locked, fixed, tamper-resistant box holding a registered rodenticide. Used in Zone 1 only.
  • Monitor (M): a non-toxic snap trap or glue board, in a tamper-resistant box.
  • Insect light trap (L): a UV unit that catches flying insects on a glue board.
  • Alert level: a count that triggers closer watch and a check of proofing.
  • Action level: a finding that triggers a deviation, an investigation and corrective action.

5. Materials and documents

  • The approved site device map (Annexure-I), with keys to the bait stations held by the contractor and the coordinator.
  • Monitors, glue-board light traps, spare glue boards and spare UV tubes.
  • The approved pesticide list (Annexure-III), with label, safety data sheet and registration details for each product.
  • The inspection record (Annexure-II), the sighting log, and PPE as each product label specifies.

6. Procedure

6.1

Qualify the contractor. Before the contract is awarded, QA confirms that the contractor holds a licence for commercial pest control operations under section 13 of the Insecticides Act, 1968[2]. Where fumigants are in scope, QA also confirms the rule 10(3A) operator licence[7]. File the technicians’ training records. The agreement must define the scope, visit frequency, reporting format and emergency call-out time.

6.2

Approve the pesticide list. Every product is registered under section 9 of the Act for the intended use[2]. For each one, Annexure-III records the active ingredient, registration number, dilution and the zones where it may be used. The contractor brings nothing on site that is not on the list.

6.3

Draw the device map. Mark every device on the site plan with a unique number (E, M or L) and record it in Annexure-I. Number and position come from a documented risk assessment, not a spacing formula[9]. Toxic bait is placed in Zone 1 only. Any change to the map goes through change control.

6.4

Maintain proofing. Doors close by themselves and seal at the threshold. Pipe and cable penetrations are sealed. Openable windows and vents carry fly-proof mesh, and drains are covered or trapped. Air curtains or strip curtains are fitted at the dock and personnel entries. For oral liquids, the airlock is fly-proofed by a fly catcher or an air curtain (Schedule M Part IX, 2.3). For topicals, insectocutors are installed outside the airlock (Part X)[1].

6.5

Remove attractants. No food or drink outside the canteen. Waste goes in lidded bins and is removed at a defined frequency. Pallets and stock stay off walls so walls can be inspected. Drains are cleaned to the cleaning schedule.

6.6

Inspect internally. The coordinator checks every M and L device at the frequency in section 8 and records each one on Annexure-II. The record shows whether the device is present, intact and in its mapped position, plus the catch (type and count) and the action taken. Change light-trap glue boards to the manufacturer’s instructions, and count the catch before you change the board.

6.7

Hold the contractor service visit. The coordinator escorts the contractor, who services each E station and records bait take per station. Treatments use only products from the approved list, in the zones the list permits.

6.8

Treat inside the building only under permit. Any chemical treatment in Zones 3 to 5 needs a written QA permit and is done outside production hours. Materials and open equipment are removed or covered first. Treated areas are cleaned, and line clearance is given, before work restarts (14.3, 16.5)[1].

6.9

Respond to a sighting. Anyone who sees a pest or its signs (droppings, gnawing, nesting, live insects) in Zones 3 to 5 informs the area supervisor and QA at once. If product or open materials are exposed, the area is isolated. The sighting is entered in the sighting log and handled under section 10.

6.10

Control birds. Fit netting or spikes on canopies, ledges and dock roofs, and keep waste lidded. Remove a bird found inside the building humanely, find its entry point, and assess any exposed materials. Check local wildlife law before removing nests.

6.11

Replace UV tubes at least every 12 months, or sooner if the manufacturer requires it, and write the replacement date on the unit record[9].

6.12

Review trends monthly. QA plots counts per device and per zone against the alert and action levels in section 7, and reviews bait take per station. Repeat activity at one device is investigated as a proofing failure, not just logged.

6.13

Review annually. Repeat the pest risk assessment, re-verify the device map against the site, audit the contractor, and re-approve the pesticide list.

No pharmacopoeia, Schedule M, WHO or 21 CFR text sets any of these frequencies. Write your own basis next to each one, because an auditor will ask for it.

9. Precautions

  • Never place a light trap above, or in line of sight of, open product or a process line.
  • No toxic bait inside the building, including at “temporary” infestations, without a QA-approved deviation.
  • No pesticide is stored on site unless the site has an approved, locked store. Otherwise the contractor brings and removes product at each visit.
  • Never move a device without updating the map. An unrecorded move makes the trend data meaningless.
  • Wear PPE as each product label requires, and keep the antidote details from the label with the safety data sheet.

10. Deviation handling

  1. For any action-level finding, raise a deviation the same day. Record the zone, device number, finding and photographs.
  2. Isolate the affected area. QA assesses every batch, material or piece of equipment that was exposed, and decides whether product is held.
  3. Find the route of entry: proofing, door discipline, deliveries, drains or waste.
  4. Correct the route, increase monitoring at that location, and verify effectiveness over the next inspection cycles.
  5. Close the deviation with CAPA. Where a sterile-area finding is involved, link it to the environmental monitoring investigation.

This SOP is a template. It needs local qualification, risk assessment and QA approval before use, and every limit and frequency marked site policy must be justified for your site. Statutory texts, including Schedule M, the Insecticides Act and Rules, and pesticide registrations, change between editions. Verify them against the current official text before you adopt this procedure.

What this page used to say, and why it changed

Until October 2026 this page carried a short SOP of the kind still common on Indian pharma sites. We have kept its core, a contractor-led programme with physical barriers at entries, and corrected five points that do not survive an audit.

  1. “UV light repellent.” Insect light traps attract flying insects. They repel nothing. That is exactly why one placed in line of sight of an open door pulls insects into the building[9].
  2. “The contractor visits twice a month.” That can be a reasonable site policy, but no regulation sets it, and the old text gave no reason for it. A frequency without a recorded basis is what an auditor challenges first.
  3. Phenyl, Savlon and Dettol mopping inside a pest SOP. Cleaning and disinfection belong in the sanitation procedure with validated agents and rotation, as in our SOP for preparation of sanitizing solution. Brand names tie a GMP document to a retail product.
  4. No device map, records, trend review or deviation route. Schedule M 17.3.10.1(f) asks for SOPs and records of pest control[1]. Records are only useful if every device has a number, every finding has a level, and every action-level finding has a deviation.
  5. “Regular fumigation” as pest prevention. Fumigation with aluminium phosphide, methyl bromide or other notified fumigants is a licensed operation under rule 10(3A)[7], and it does not replace exclusion. Formaldehyde fumigation of a microbiology laboratory is a disinfection process with its own controls. See the SOP for fumigation of microbiology lab.

Pest control audit questions

Check the rest of your premises against the same text

Pest control findings usually appear in the same inspection report as proofing, HVAC and layout findings. The Schedule M compliance dashboard maps the premises requirements clause by clause, so you can check the whole building against the notified text this SOP is built on.
