Flies are more than a serious nuisance, as they spread disease through their feeding and breeding habits. They walk over all manner of germ ridden surfaces, then over our food sources. They feed by vomiting acidic saliva onto food surfaces then suck up the resulting mush.
There are over 120,000 species of fly worldwide. Fortunately your home is only susceptible to a handful. Blow flies, House flies, Cluster flies, Fruit flies and Midges are our main culprits.
