Egg
Eggs are placed in or near water, depending on species.
Inspect water-holding containers and clean suitable surfaces.
Egg → aquatic larva → aquatic pupa → flying adult. Egg-laying habits vary between Aedes, Culex and other mosquitoes; development depends on species and conditions. Diagram is schematic, not to scale. Timing varies with species, temperature, food and local conditions.

What keeps them going?
How they feed
Adults use plant sugars for energy. Females of many species take blood meals to support egg production. Larvae feed in water; pupae do not feed.
How they survive
Standing water supports the immature stages. Some Aedes eggs can withstand drying and hatch when flooded, so emptying a container once may not remove the problem permanently.
How do they reach your premises?
Adults may develop in small containers or other water-holding habitats nearby, then move to people and sheltered resting areas. They can also arrive from breeding sites beyond the property.
Water held in containers, blocked drainage, plant saucers and other standing-water sources can support development. The relevant habitats depend on species.
Signs worth investigating.
- Recurring adult mosquito activity or biting.
- Standing water around the property.
- Larvae in water-holding containers or other suitable habitats.
A sign is a reason to inspect, not proof of the species or extent of activity.
Control that addresses
the source.
Address breeding water and immature stages, then assess adult activity, exclusion and the wider surroundings.
- Survey accessible water-holding sites and the pattern of adult activity.
- Prioritise source reduction and discuss water-storage or drainage issues.
- Consider suitable larval or adult control only where justified and permitted for the site.
- Coordinate timing and access instructions with the premises team.
- Repeat inspections of breeding areas and review activity after conditions change.
Fine Enterprises PCO during site treatment. The method for your pest and premises is agreed after assessment.
Fogging alone does not remove breeding water or provide a permanent barrier. A sustained programme depends on source management and repeat assessment.
We agree the preparation, treatment scope and review points for your premises. Method, timing and follow-up depend on the confirmed pest, access and response to treatment.
Why a problem can continue.
- Relying on fogging while leaving breeding water in place.
- Forgetting small containers, covers or blocked drainage.
- Expecting an outdoor site to stay permanently mosquito-free.
Make it harder to return.
- Empty or manage unnecessary water-holding containers.
- Maintain drainage and cover appropriate water storage.
- Repair window screens and follow locally relevant bite-prevention advice.

Questions we can help with.
Is fogging enough?
No. Breeding sources must also be addressed.
Can mosquitoes breed in small containers?
Some species can use small water-holding containers. Regular inspection is worthwhile.
Can you promise no mosquitoes outdoors?
Outdoor activity is affected by surrounding conditions. The aim is to reduce risk and activity through an appropriate programme.
