There is no animal or insect I despise more than Bremsen (German horseflies). These devils are as small as a housefly, but unlike the housefly these bloodsucking imps will chase you a hundred yards to get their fix. They are attracted to sweat, so walks in their territory on warm days will invite being jumped. The bite, which is painful, isn't the worst part of the attack, it's the swelling and merciless itching. The swelling could be as big as a golf ball and the itching could last for days. I have had the unfortunate experience of being violated by these filthy creatures and do everything short of buying a flamethrower to keep them off my property.
