Flies in Ireland – Top 6 Questions


Flies are definitely one of the most annoying insects in Ireland. And they can be dangerous. Spreading illness, and even biting in the case of one of the species. We find at this time of year infestations are at their peak. And we are often inundated with questions about this pest. So we answered the 6 most common questions we get asked.

1. Why is there so many flies in Ireland?

The answer to this question is simple. Our weather creates the perfect environment for this insect to thrive. As they love mild to warm weather. And considering our winters tend to be more mild than freezing, they typically survive all year long. During summers, the fly population increases. As our temperature averages twenty degrees. However, heat waves cause reproduction to speed up. So, when temperatures reach over 23 degrees, numbers soar.

2. Can a fly bite you in Ireland?


The only species of fly that bites in Ireland is the female horsefly. Typically, they are only found near horses, cattle and woodlands. The bites can be painful and become inflamed and itchy immediately. Scratching can lead to infection. If bitten, keep the area clean with antiseptic soap and warm water. And apply a cold compress intermittently.

3. Why are there suddenly so many flies in my house?

A swarm means you have an infestation. Either inside or nearby your home. Fly infestations happen fast. One or two flies around your home can turn into a full-blown infestation in a matter of weeks. One fly can lay over 1,000 eggs in its 30 day lifetime. Fly larvae reach maturity in 7 – 10 days. And then they start reproducing themselves. Before you know it, one fly has turned into thousands in a few short weeks. If you see a swarm of flies that means dozens of eggs have already hatched. And more will be laid and hatching shortly.

4. How do they get into my house?

They gain access through open windows and doors. And even air vents. Attracted by exposed food, accessible rubbish bins and unclean drains. Eliminating entry points and practising good food hygiene are both easy ways to prevent them from infesting your home.

5. Do they spread disease?

Flies harbour multiple illnesses that can infect people. Some of the most common include food poisoning and diarrhoea. But how do they spread these illnesses exactly? Flies are not picky eaters. They consume human food, pet food, rotting food and even faeces. So they are forever picking up pathogens. Then, leaving them behind wherever they land. Transferring in a matter of seconds. Additionally, flies vomit and defecate when they feed. Consuming food that a fly has landed on will put you at risk for catching a fly-borne disease.

6. How can I get rid of flies?

Depending on the level of infestation, getting rid of an infestation can be done by yourself, or by a professional. A small infestation can be taken care of yourself. Firstly, kill any you find onsite. Do not give them the opportunity to reproduce in or near your home. Shop bought sprays should be sufficient at this point. Secondly, eliminate breeding site, such as bins and drains. And install protective screens on air vents, if possible.
