Warm, humid conditions create ideal breeding grounds for flies, often resulting in a spike in infestations during this time of year.
Rentokil has said flies are 'more than just a nuisance' and can pose a health risk as they can spread bacteria like E. coli and Campylobacter.
These bacteria can contaminate food, surfaces and equipment.
Early intervention is important to avoid infestations and related health hazards, the company said.
Colm Moore, Regional Technical Manager at Rentokil, said flies thrive in warm weather during the late spring and summer months.
"Identifying potential problem areas and acting early can significantly reduce the risk of an infestation,' he said.
To prevent fly infestations, Rentokil recommend sealing entry points such as windows, vents, doors, and pipes.
Homeowners and business owners are also being advised to dispose of food waste and to keep compost bins covered.
Screening kitchen windows and doors and cleaning drains and waste areas regularly are also seen as two vital preventative measures.
Just two flies can produce up to 500 eggs, which can hatch in as little as seven days, so it's vital to tackle this pest problem quickly.
Addressing these areas and implementing effective pest control measures can help mitigate the risks associated with fly infestations.
Rentokil's EcoCatch Fly Trap, is a sustainable, non-toxic solution designed for outdoor use and constructed from recycled plastic.
The company said the trap utilises the 'contrast effect' and uses sweet-scented liquid food lure to help capture common fly species, such as house flies, blow flies, and fruit flies before they enter homes or commercial premises.
It added that it is ideal for various outdoor business spaces such as hospitality venues, hotels, pubs, gardens, terraces, and external waste areas.
This is because it does not require electricity and the unit can be wall mounted, hung or placed on a flat surface.
"We recommend a proactive approach, particularly for commercial premises handling food,' Mr Moore added.
'Our EcoCatch Fly Trap offers an effective and sustainable external solution to help keep fly numbers under control by allowing species identification, facilitating root cause analysis during the peak season.'
