The future of pest control

We know the scientific and industrial revolution was a springboard for the evolution of pest control.

Then, the third and fourth industrial revolutions (1960s to present) introduced various technologies that have benefited all aspects of pest control. We’ve had advances in AI and machine learning, electronics, robotics, biotechnology, computing, nanotechnology and the Internet of Things, to name but a few.

These developments are accelerating and will revolutionise pest control tools and management, enhancing efficiencies, precision and sustainability.

This is necessary in a world where sustainable technologies and practices are an increasing priority in every pest control innovation. They impact the choice of materials, whole-life design of products, harmful chemical usage and developments in new compounds to make them safe for non-target specific and the environment.

But where is it heading? Here are nine examples of how these technologies are being or could be further harnessed for pest control.

1. Biotechnology and genetics manipulation for a safer future

This topic is a vast area for innovation and could, one day, lead to a world without mosquito-transmitted diseases like malaria.

For mosquitoes alone, there are ongoing developments on multiple fronts. The World Mosquito Program’s Wolbachia project breeds Aedes mosquitoes that are infected with the naturally occurring bacteria which suppresses the ability to transmit viruses that cause human disease. Using naturally occurring microorganisms that can disrupt pathogen lifecycles, reduces the need for chemical interventions while minimizing harm to non-target species.

A biological weather station can recognise different mosquito species by analysing their wingbeats and capture specific ones. It sends this data to a cloud platform and stores the mosquitoes for future genetic disease analysis. 

These stations, when connected in networks, generate a large stream of data. This data, combined with genetic and environmental information, can be processed by AI systems to predict and address disease outbreaks and even climate changes.

In Tahiti, scientists are testing the sterile insect technique as a means of reducing dengue transmission by Aedes mosquitoes. The technique has been widely used in agriculture for 60 years and is now being tested in several countries for preventing mosquito-borne diseases.

Genetic analysis of air and water can identify pests (and people) in the local area and diseases they may carry. Sampling air in a Danish forest discovered 50 species of wild animal were living in the locality. DNA collected this way was able to identify disease-associated mutations and show the genetic ancestry of local animals. This could be useful on business premises to identify infestations and pest populations, allowing for pest activity to be tackled quicker and mitigating the risk of infection from disease-carrying pests. 

2. Looking beyond traditional rodenticides for environmental responsibility

While there haven't been significant advancements in rodenticides for many years, they’ll continue to be a viable choice — in integrated pest management — for the foreseeable future. This is stimulating both the development of new physical methods of control to avoid the need for chemicals and finding new ways to use existing chemicals that are environmentally friendly. Microencapsulation of existing compounds with, for example, gelatine and shellac, is a promising development in the medium term. A carbohydrate layer prevents carnivores from digesting the layer and thus the poison. This would allow rodenticides with an acute mode of action to be used and avoid bait shyness while protecting other wildlife. Other possibilities that are being tested include repurposing existing pharmaceuticals, modifying the structure of existing compounds and using more active isomers of existing compounds that also break down quickly in the environment.

3. Advancements in the fight against malaria

Mosquito up close

Malaria infects approximately 250 million people yearly and kills 620,000 – a staggering number, particularly when 95% of these occur in Sub-Saharan Africa alone. What’s more, 80% of the deaths are children under five. And, the ramifications aren’t limited to the population. In fact, where there are large numbers of infected individuals, the economies of developing countries are also suppressed.

For many years, malaria cases were successfully being reduced, but this was overturned with the COVID-19 pandemic. Numbers have now increased and mosquitoes are showing widespread resistance to some insecticides. 

To tackle the rising numbers, WHO is evaluating various alternative interventions that can offer new tools for eliminating the mosquitoes from urban areas and the disease. 

These include physical, chemical and biological methods – from traps and new pesticide formulations to mosquito genetics manipulation, sensory interference (chemosensory interference) and sterilisation.

4. Internet of Things (IoT) and sensor networks for real-time monitoring

The use of millions of IoT devices automatically monitoring pests and sending data to cloud systems will greatly expand. It will include a wider range of pests and types of sensor, such as environmental, optical, sound and gaseous — to detect volatile organic compounds (VOCs) that are emitted by specific pests. This data will help predict and identify infestations early, allowing for prevention, rapid response and more-targeted interventions.

5. Leveraging Big Data for pest control advancements

The vast amounts of data collected will need more sophisticated tools to make full use of it. Various features of Big Data analytics have been talked about for years but we are only now beginning to realise its potential as we learn how to apply multiple sets of data in a practical way. More sophisticated tools for combining and analysing data from a wide range of sources and formats, such as pest monitoring, identification, pest biology, weather patterns, environmental data and pest control activities, will give holistic insights into pest dynamics and help optimise pest control strategies. Adding specialised machine learning and AI tools to the traditional analytical tools could generate new insights and give recommendations based on large knowledgebases on pests.

At Rentokil, we’re already using AI to study the relationships between weather patterns and pest infestations by analysing the billions of items of pest data gathered automatically by our IoT pest control devices around the world. This shows the datasets and modelling systems that are the most suitable for predicting pest infestations in geographic regions and on customer sites.

6. The AI and machine learning revolution for autonomous decision-making

AI and machine learning are already revolutionising pest control, for example with systems that use visible light and infrared cameras to detect and recognise pests and their behaviours. This is perfect in restrictive environments, for informing control strategies and optimising management. 

It means continuously 'learning' and refining detection skills with rules and logic that could, one day, lead to systems being able to autonomously decide how best to operate and manage devices for optimum efficiency. 

These are systems and devices that will only evolve and become increasingly more sophisticated and effective as AI tools advance.

7. Robotic systems and drones for precision applications

Robotics engineering, which combines advances in mechanical, electrical and computer engineering, will enable more sophisticated machines for specialist applications. For example, these systems could detect pests, gather essential data from the environment and control pests in human-restricted environments such as automated warehouses and restricted environments. They could be equipped with a range of sensors, such as sound, optical, gaseous and infrared.  Of course, AI will also play a role in their operation and reduce the need for human intervention.

Drones and ground-based robotic systems are used to monitor agricultural and other outdoor areas autonomously using an array of sensors and deliver precise applications of pesticides or biological control agents to specific areas, reducing chemical usage and minimising environmental impact.

8. The power of satellite remote sensing in pest control

Remote sensing technology on satellites records and monitors from small to large-scale landscape features, vegetation health and environmental factors that influence pest populations using numerous types of optical and other waveband sensors. The images can show where pest infestations are in crops or where plants are damaged by drought or fire and susceptible to pests and guide pest management decisions.

9. Elevating pest control training with augmented reality (AR) and virtual reality (VR) 

AR and VR technologies can be used for training pest control professionals to improve their skills. Simulated scenarios and visualizations can enhance learning and decision-making skills, removing some of the restrictions of having to set up physical spaces and find sites for practical training. It could also be applied to customer staff training and as a sales tool to give customers an immersive experience of, for example, how a pest control plan could operate on their own properties.

The path to the future

Throughout the history of pest control human ingenuity has been applied to finding ever-more effective means of controlling pests. As science and technology advanced, pests adapted and new pests thrived, more sophisticated and effective tools and practices were developed to prevent and control them.

Pest control will face new challenges and opportunities in the future, as the world changes due to factors such as climate change, urbanisation, economic factors and human behaviour. Pests will adapt and present new threats and pest control will need to continuously adapt to these changes. However, the scientific and technological developments across the many disciplines described above are addressing the challenges across multiple fronts and providing innovations that will improve both the effectiveness and sustainability of pest control for the long term.
