Are house flies dangerous?
“Keeping flies away from your food is vital for protecting your health. The adage ‘if you followed a fly for a day, you wouldn’t eat for a week’ is entirely accurate,” Natalie Bungay, Technical Officer, British Pest Control Association tells Country Living.

What attracts flies in your house?
“Spotting a few flies buzzing around does not necessarily mean you have a serious fly problem, although you should probably start keeping an eye out for other tell-tale signs, such as small dark clusters of spots in light areas and the presence of maggots,” David Cross from Rentokil continues.
