Control Fruit Flies in your Home or Business

Fruit Flies in Auckland found mostly in kitchens hanging around the sink or rubbish bin are a problem in most kitchens from one time or another. Normally they don’t become a large problem and can be resolved with sanitation such as keeping kitchen drains and rubbish bin areas clean. However EcoSan Solutions has seen many situations where this fruit fly gets out of control and can become very difficult to control. Sometimes numbers of this fly can increase dramatically, working their way into different areas of the building and infesting kitchens, lunch rooms, office areas and multiple floors and apartments of residential complexes.

Although this is a very small fly they can cause considerable distress, pestering staff in commercial kitchens, office workers and clients. They often swarm people at desks when opening snacks or their lunch. They can fly in faces attracted to light emitted from computer screens.

The fruit fly family

Fruit flies are in the same family as Mosquitos. They don’t bite but can come in very large numbers if they have the opportunity to thrive.

Red Eye Fruit Fly or the Common Fruit Fly is shaped with a similar profile to the common house fly but much smaller at just 3.18 mm long. Often hanging around food sources such as empty wine bottles in the rubbish bin, around rubbish collection area and around drains in the kitchen.

Black Eye Fruit Fly also known as Phorids shares a similar body shape as the red eye but is a little larger at about 4.78 mm. They possess a more robust upper body shape. Characteristically they are more active in comparison to the Common Fruit Fly. They will be in your face when you break open your lunch before you can take a bite. When they are able to establish themselves they can nest in buildings in much larger numbers than accustomed to with the Common Fruit Fly which tend to remain more localised and more docile, the black eye will spread out throughout buildings.

Drain Fly (Psychodidae) Less likely to be confused with a fruit fly, they can be found in similar locations. At their largest they around 5mm large and so the largest of the three flies. They can have a slightly fluffy appearance due to tiny hairs on their body.

Fruit Fly Treatment methods

Insecticide Residual treatments
The flies mentioned above are the most resistant to insecticide sprays and residuals of all flies which we normally deal with. The Black Eye Fruit Fly will see almost no decline at all after spraying insecticides. This can apply to both fly spray cans to industrial residual and knock down treatment.

It is important to bring the target under control in the early stages as if nests become established they may not be resolved easily with simple conventional methods and may take several weeks to resolve. Eco San Solutions has specialised residual solutions to assist with knock down and residual control of these flies which can be used as a tool to control these pests.

Trapping solutions
There are several trapping methods which we can employ to control the numbers of these irritating insects. UV light traps with specialised light wave lengths to attract these fly types can be very successful in isolating Fruit Flies. Lure traps are also effective and have proven quite popular with our corporate clients.

Sanitation Solutions
Various sanitation services may need to be employed to address the eggs and larvae of the Fruit Fly. Where these issues are not addressed, the lifecycle may continue to persist despite insecticide and trapping method. Sanitations may include treated water drains such as kitchen drain networks and also storm water drains. Appliances and rubbish collection areas may need inspection and improvements.

Larvae control treatment
Products which control the larvae life cycle can be used in areas of nesting where Fruit Flies lay their eggs. These solutions block or interrupt hormones unique to insects morphing stages and can prevent larvae from morphing to adult winged insect.

Obstruction techniques
Various screens and sealing methods may be employed to achieve fast improvements to fruit fly numbers, in some cases we have seen huge improvements in difficult to resolve cases by adopting these methods.
