How should nature-oriented resorts approach pest control?

Open spaces integrated with forests, coastlines or lakes are a defining feature of premium resort environments and a key part of the guest experience. However, close proximity to natural ecosystems also means that resorts are continuously exposed to pest pressure from the surrounding environment. Insects, reptiles and other nuisance wildlife may move into guest and service areas in response to weather conditions, seasonal changes and natural breeding cycles.

Pest risk is therefore not distributed evenly across the property. Guestrooms, F&B areas, storage areas, waste zones, landscaped spaces and technical areas should be assessed separately according to high-risk pest areas in hotels and resorts.

The challenge for resort management is to protect guests from pest-related nuisance without compromising the surrounding landscape or ecological balance. Overreliance on broad-area pesticide spraying may affect vegetation and create odours that interfere with the guest experience. A hospitality-focused Integrated Pest Management (IPM) programme provides a more balanced approach by combining targeted control, prevention, monitoring and consideration for the surrounding environment.

1. Sources of pest pressure in nature-based resorts

Resorts located close to natural environments are often surrounded by dense vegetation, natural water sources and high humidity. These areas may already serve as natural habitats for many insect species before resort development begins. Swimming pools, decorative streams, landscaped gardens and other water-retaining features may unintentionally create additional moisture and standing-water conditions that support mosquitoes, flies, ants and millipedes.

Pest risk is therefore not distributed evenly across the property. Guestrooms, F&B areas, storage areas, waste zones, landscaped spaces and technical areas should be assessed separately according to high-risk pest areas in hotels and resorts.

Vietnam's tropical monsoon climate, with high temperatures and substantial rainfall, can accelerate the development and breeding cycles of many insect species. Open architectural designs with large doors, terraces and outdoor dining areas can also provide more opportunities for insects to enter guest and service spaces, particularly where light sources are visible at night. Organic waste generated by food-service operations can create odours and food sources that attract insects from surrounding areas.

2. Limitations of conventional pesticide spraying in open resort environments

Some resort operators still rely on pesticide spraying according to fixed schedules or only take action after pest activity has noticeably increased. This approach can have significant limitations in nature-based hospitality environments. “Regular pest management” does not mean that pesticides should automatically be applied on a fixed calendar date. Control frequency should be adjusted according to risk level, seasonality and actual monitoring data.

Outdoor pesticide applications may be affected by wind, sunlight and rainfall, which can reduce coverage or shorten the duration of effective residues depending on the product and application method. Adult-targeted spraying may reduce exposed insects at the time of treatment but may not address larvae, eggs or breeding sites concealed in vegetation, water or other protected locations. Once treatment effectiveness declines, insects from surrounding natural areas may re-enter the resort.

This is why responding only after pest activity increases can create a repeated cycle of treatment, recurrence and retreatment. Over the long term, businesses should also consider the cost of reactive pest control compared with proactive prevention.

Broad-area pesticide spraying may also create environmental risks. Depending on the product and application method, pesticides may affect sensitive vegetation, non-target organisms, water quality or guest comfort through residual odours. These risks can conflict with the environmental and wellness expectations associated with nature-focused hospitality. Resorts must also consider the impact of pest management activities on the guest experience. During periods of high occupancy, pest management activities should be discreet, low-odour and designed to minimise disruption to guests.

3. Risk zoning and hotspot control across resort areas

Effective pest management should be organised by functional zone, with control measures selected according to the risk profile of each area.

Guestrooms and private villas are among the most sensitive areas because pest incidents can directly affect the guest experience. Technicians can work with housekeeping teams to inspect mattress seams, bed frames, curtains and other potential bed bug harbourage points for early signs of activity. Concealed areas beneath sinks, around floor drains and within bathroom service ducts should also be inspected for cockroach, mosquito and other pest activity associated with drainage or utility routes.

Restaurants, beach bars and central kitchens can become high-risk areas for flies, ants and German cockroaches because of food, moisture and waste generation. Floor drains, grease traps and waste-handling areas should be cleaned according to a defined sanitation schedule to reduce food and organic residues that support pest activity. Kitchen entrances may require appropriately specified air curtains, PVC strip curtains or other physical barriers to help reduce flying insect entry. For flying insects in F&B areas, the placement of monitoring devices can significantly influence capture and monitoring performance.

See more about LED insect light trap placement and the use of flying insect capture data.

Landscaped gardens, water features and external service areas form an important outer layer of pest prevention. Control measures should focus on maintaining drainage, inspecting planters and landscape features, removing or managing suitable harbourage and reducing conditions that may support mosquitoes, centipedes, fleas and reptiles such as snakes.

4. Sustainable pest management in resorts using an IPM approach

Integrated Pest Management (IPM) helps nature-based resorts address pest risks at their source, reduce unnecessary pesticide use and maintain more stable long-term control.

A key element of IPM is reducing the food, water, harbourage and entry conditions that support pest activity. Operations teams should remove accumulated organic debris from gutters, eliminate unnecessary standing water after rainfall and maintain vegetation around walkways. Where permitted and appropriate, registered biological larvicides may be used in suitable water features to control mosquito larvae before they develop into adults.

Monitoring devices provide an early-warning network for pest activity across the resort. In suitable food-service support areas and service corridors, Vectothor LED insect light traps with glue-board capture systems can be used to monitor and capture flying insects without electrically fragmenting them. Enclosed mechanical rodent stations and targeted gel bait for cockroaches or ants can be positioned in concealed service areas to reduce unnecessary exposure in guest-accessible spaces.

When adult mosquito treatment is required in landscaped areas, ULV misting or other appropriate mosquito-control techniques may be used during suitable low-activity periods with equipment selected for the treatment objective. Where residual treatment is appropriate, application can target mosquito resting surfaces in low vegetation while using quieter equipment and scheduling work to minimise disruption to guests.

6. Frequently asked questions

Can a resort near a forest eliminate 100% of naturally occurring insects?

No. Complete elimination of naturally occurring insects is neither realistic nor an appropriate objective in a functioning ecosystem. The objective of an IPM programme is to reduce pest activity to acceptable risk levels, limit entry into guestrooms and food-service areas, and manage hotspots before they affect guests.

Will pest management activities create unpleasant odours for guests?

VFC PestMan prioritises targeted gel baits, mechanical traps and registered pest control products with clear product information, including low-odour options where appropriate. Technicians schedule work during lower-activity periods and use quieter battery-powered equipment where appropriate to minimise disturbance and odour in guest areas.

How can termites be managed in wooden villas while minimising damage to the structure?

Technicians may use Termatrac detection equipment to help identify termite activity within concealed structures and reduce the need for unnecessary destructive inspection. Where suitable, the Exterra monitoring and baiting system can then be installed around the property to support colony-level termite control.

Why should mosquito larvae and breeding sites be managed instead of focusing only on adult mosquito spraying?

A female mosquito can lay a large number of eggs during its reproductive cycle, depending on the species and environmental conditions. Adult mosquito treatment alone does not address the underlying breeding source. If standing-water habitats and larvae remain unmanaged, new adult mosquitoes may continue to emerge and maintain pest pressure around guest areas.

Pest management for resorts close to natural environments requires a risk-based approach that combines an understanding of pest biology with consideration for the surrounding ecosystem. A well-designed Integrated Pest Management (IPM) programme can help resort managers reduce pest risks, minimise unnecessary pesticide use and protect the guest experience while respecting the surrounding environment.
