During our daily practices of managing pests, we often are asked by customers “what are these flies always doing in my bathroom?” and “I keep spraying them, but they always come back”.
The simple answer is they are most likely to be a drain fly.
There are a few flies that can utilise drains for breeding which gives them the common name drain fly. Drain flys are also commonly known as the Moth Fly, these flies are fairly small, with hairs that are easily identifiable around the wings and can populate to large numbers quickly.
We recently conducted a cockroach treatment at a unit in Parramatta where drain flies were evident to the main bathroom and laundry. After questioning our Amalgamated Pest Control technician who explained what they are and how they can be managed, our technician went out to his vehicle and grabbed his foaming kit and completed another successful drain treatment.
Drain fly characteristics
The Moth Fly is possibly the most common drain fly found in domestic properties and very common at commercial properties. They seek out decomposing organic matter to deposit their eggs in. Inside your home this matter exists inside common drains such as the shower, sinks and floor wastes. Once their eggs hatch the larvae feed on microbiological organisms inside dirty drains. Due to this fact is why customers keep ‘spraying’ them and they keep coming back. The hatched adult flies may be killed but the larvae are still hatching, feeding in the drains and emerging from these drains as adults. Like many pests, if we don’t tackle the source, the problem will remain.
How can I get rid of drain flies?
If you have a problem with the Moth Fly, it’s recommended that you call in an expert to treat the problem for you. The one sure way to manage the problem is to treat the drain. This is done with specialised equipment and non-toxic biological agent combined with a foaming agent which will break down the decomposing organic matter which the Moth Fly larvae feed on. Cleaning the drain, leaving no available food source will control the problem as adults will seek other places to lay eggs. In most cases only one treatment will be required, in the more extreme infestations more than one treatment may be required.
A Foaming kit is filled with microbial concentrate and foaming agent. The Foaming kit is hooked up to compressor and the drain is foamed until the drain is full. The foam pushes out the water and starts to breakdown the decaying organic matter inside the drain. The same process is undertaken with any connecting drains.
Once the treatment is completed the matter in the drain that supports the larvae of the Moth Fly is gone and therefore these annoying flies are no longer a problem for you.
This procedure doesn’t take long to complete and can easily be carried out in addition to any other pest management treatments being conducted at your home. Just ask our technician on his arrival or our office staff when you book your treatment.
