Fly control in Rotterdam
Flies repeatedly appearing in your Rotterdam home, kitchen or business? We identify the fly and investigate the source. Effective treatment also needs to address that cause.
- ✓ Treatment and costs agreed in advance
- ✓ Urgent visit within 24 hours where available
- ✓ A report after the visit
Identification: what have you found?
Fruit flies, drain flies, fungus gnats, phorid flies and cluster flies have different sources. Tell us where and when they appear: near food, drains, plants, concealed spaces or seasonally at windows. A photo helps avoid the wrong approach.

These are comparison images, not photographs of your property. Magnification varies; on-screen size does not indicate body length.
Fruit flies near fruit
Check overripe fruit, empty drink containers and food residues.
Drain flies near drains
Fuzzy, moth-like flies may indicate organic drain deposits; the location alone does not identify them.
Fungus gnats near compost
Check persistently damp potting compost and plants; these differ from biting mosquitoes.
Phorid flies and hidden sources
Small flies that often run quickly can occur near hidden organic material. Recurrence after cleaning needs further source checks, sometimes around a drainage defect.
Cluster flies near windows
Numerous larger flies in an upper room can relate to overwintering. Species and season determine the approach.

A plan for your property.
Hospitality and waste
In a restaurant, takeaway or kitchen, inspection may include waste, drains, deliveries and cleaning points depending on the fly species. The plan fits food preparation and opening hours.
Apartment and shared cellar
Report small flies in an entrance hall or cellar separately. A shared-area source requires access and coordination with the manager.
Warehouse and port business
Around stored goods, we inspect organic materials, waste flows and access routes. Monitoring tools are selected for the way the premises are used.

Identify species and breeding source
We examine insects, locations and possible sources. Drain problems or concealed contamination may require further access or investigation. Adult flies are not always found next to their breeding source.
Address the source
Food residues, drain deposits, plant material or another confirmed source require targeted action. Cleaning, removal or repair responsibilities are agreed. Suitable additional control or trapping can support the plan.
Evaluate new activity
Adult flies can remain after source measures. We assess progress and investigate a missed source if activity persists. Your report records actions, owner responsibilities and agreed checks.
Costs and proposal scope
The source, access and scope of investigation determine the proposal. Cleaning or building/drain repairs by another party are not automatically included. We specify the monitoring and treatment performed by Eversor.
Preparation and aftercare
Before the visit
- Keep a clear photo or specimen and record peak times and exact locations.
- Provide access to drains, waste storage or affected areas; mention odours, leaks and previous products.
After the visit
- Carry out agreed source and cleaning measures; a fly lamp alone is not always sufficient.
- Record fresh activity at the same locations and report recurrence at the agreed review point.
Practice and agreed work
Example situation: flies keep returning near a drain
A clear photo and location support identification. Accessible organic deposits are removed appropriately. Recurring activity prompts checks for a hidden source or defect; the owner arranges required drainage repairs. Findings by location and date show whether source measures work.
Questions about this approach
Are small flies always fruit flies?
No. Drain flies can occur near drains, fungus gnats around plants and phorid flies at other organic sources. Identification comes before assuming the source.
Is a spray or lamp enough?
It may reduce adult flies but does not automatically remove the breeding source. Persistent activity requires source investigation.
What if the source is behind a wall or floor?
Additional access and a building or drainage specialist may be needed. We record findings and discuss further work before it starts.
Can you help food and hospitality businesses?
Yes. Source investigation, food protection, cleaning and monitoring are coordinated with your operations. See our Rotterdam hospitality route too.
