Test your knowledge

fly drawing Houseflies are unpleasant, annoying and can be dangerous. They breed rapidly and under the right conditions carry diseases on the sticky pads on their feet, on the fine hairs on their legs and inside their stomachs. Flies will sit on dog faeces and then gladly wander around your lunch before you eat it. You end up eating some of the dog dung which the fly carried along on his hairy, sticky legs and you could end up being sick because of the germs the fly placed on your lunch. Not a nice thought is it? You should always cover your food and place perishables in the fridge. Wash your hands before you handle food and clean the area where food is going to be prepared or kept. Of course you should always wash your hands after you have been to the toilet.
