Sterilization of gull eggs.
The concentration of gull populations in city centers degrades the daily lives of residents: noise pollution, soiled facades and roofs, and aggression during nesting season. Manual interventions are slow, dangerous at heights, and place a heavy burden on municipal technical teams.
Conduct an effective, secure, and compliant gull regulation campaign without disturbing residents: mapping of gull nest locations, fast and safe egg sterilization, and complete documentation of proofs for your annual reports, with photos provided for every treatment performed.
Nest mapping and detection
Proven effectiveness in photos

85% of Asian hornet nests are invisible to the naked eye. Our AI-connected drone systems can detect and map 100% of nests located in trees.
They secure their public spaces with our technology

gull eggs sterilized each year in France with a success rate of over 90%. Photographic evidence provided.
Regulation has become a necessity.
"We had never seen anything like this. Since the start of the nesting season, the town has recorded over 100 gull nests on rooftops in the city center and on public buildings. We used to see about thirty nests a year. Now, reports are skyrocketing."

Controlled management:
Map, anticipate, regulate
We do more than just treat and sterilize visible eggs with 100% eco-friendly vegetable oil; we regulate the population in a safe and ecological manner. Our drone pilots, trained and certified by ornithologists, target the most invasive species.
Nest census
The situation
Seagulls are settling permanently in cities, causing nuisances and tensions during the nesting season. Preventive regulation, such as egg sterilization, allows for controlled and sustainable population management.
Our drones perform reconnaissance flights over rooftops identified by the town hall and by citizens on the reporting website provided free of charge by Cominthesky. Sometimes, a complete sweep of the municipality is carried out to precisely quantify and locate every nest (supported by GPS coordinates and photos). Real-time tracking and mapping on our web app, which is filterable and downloadable.

Sterilization: targeted spray treatment
The situation
Drone-based sterilization is much safer and less restrictive than conventional methods.
The drone positions itself at the height of the nest without requiring access to private property. The vegetable oil-based solution is sprayed directly onto the eggs, creating a film that prevents gas exchange and stops the embryo from developing. This method allows us to treat multiple nests in a single flight, making it twice as fast as traditional methods, with over 90% of births prevented.

Neutralization
The situation
Managing the seagull population is time-consuming for local authorities: census taking via email and phone, tracking with service providers, and reporting to the town hall and prefecture…
- Monitoring: photos checked and validated by the remote pilot are displayed in real time on the web app map provided to your town hall.
- Accounting and reporting: our AI detects eggs and chicks and automatically counts them by address and neighborhood. Data can be filtered and downloaded to simplify your tasks.


Falcon
Designed for precision sterilization of gull eggs
Highly stable drone
A drone designed for sufficient battery life despite a heavy payload, with exceptional stability that allows for stress-free operation.
Ultra-HD camera
To distinguish between gull species, spot hidden chicks, and verify that the vegetable oil has been properly applied to the eggs.
Our detection AI
Our AI, trained on thousands of images, can distinguish between multi-colored chicks and gravel, saving you from having to check every single photo.
Community
Automatic transmission of photos taken by the drone to a custom-built app for local authorities, allowing them to monitor and manage the mission in real time.
Why sterilize gull eggs by drone with Cominthesky?
Dangerous current treatment
Today, sterilizing gull eggs using rope access technicians involves putting people at risk and disturbing residents in their own homes.
A cost-effective solution
The drone solution is twice as fast, requires no cradle, and generally cuts costs in half.
Transparency
The web app provided allows you to track our mission daily and monitor the quality of the work performed: photos from the second visit demonstrate that the eggs sterilized during the first visit did not hatch, providing proof of the service's effectiveness.
Significant time savings
Citizens report nests to be treated directly on the reporting website that we provide to you free of charge. The file of addresses to be treated, their mapping, and the tracking of completed treatments are automated and form the essential basis for detailed reporting.
Manage your pest control campaign in real time
Cominthesky provides you with the tools to manage the crisis:
Frequently asked questions
No, the injection is performed inside the nest, limiting the impact on surrounding wildlife.
Our drone can reach nests located at the tops of the tallest trees, areas often neglected by ground-based methods.
A simple safety perimeter is set up under the drone, but the operation is quick and does not require blocking off an entire neighborhood.
Do you have other questions?
Dealing with a gull infestation first requires quantifying and geolocating them.
