Although no one seems quite prepared to agree on the reasons why, it is commonly accepted that the Fairy Folk problem is becoming ever larger. In an attempt to combat this I assembled a crack team of experts in this field in order to research the most effective ways of killing the most common breeds of Fairy folk. This is what we have managed to assemble from our findings - the most complete guide to fairy folk yet. I hope you will find it useful.

They will be sorely missed.

Elves - These are the only human sized Fairy Folk, and therefor easy to spot. They are also the most clever and evil of the Fairy Folk. They can only be killed by iron and steel.

Faeries - Like Fairies, but larger and a lot more stupid. Fully grown they are about 40-50cm tall with butterfly like wings which, because of their relative size, are completely useless. They are best killed by impaling then on a chopstick. Pine is best.

Fairies - Although in books these creatures are usually portrayed as good, in real life it is quite a different matter. Unlike Faeries they can fly, and so can be hard to catch. To dispose of these winged fiends impale them on a tooth-pick.

Flower Fairies - These are not fairies at all, but in fact a breed of gnome that has specially adapted to living on flowers. They can be killed by most common brands of pesticide.

Gnomes - By far the most stupid of all the Fairy Folk Gnomes are easily distinguished by their ridiculous hats and inability to string together a coherent sentence more than four words long. To kill them, biting off their heads is advised. It is best to spit the heads out, though, as they may cause food poisoning.

Goblins - These little bastards are easily recognised by the bright green pigment in their skin. They can be disposed of by covering them in saw-dust and then running away or hiding behind a large heavy object, as they are liable to explode.

Imps - As well as being notable for their artistic ability, Imps are also well known mischief makers. If your Imp becomes more trouble than its worth, hit it very hard with a dead chicken.

Lepricorns - These little Irish buggers, with their distinctive accent and green clothing, will quite happily steal your money, replacing it with a ‘lucky' four leaf clover. To kill these creatures Sellotape them to a light bulb until medium rare. It is best to do this in a well ventilated room as they tend to smell a bit.

Pixies - Probably the most common type of Fairy Folk, Pixies enjoy nothing more than annoying people. Their favorite tricks include moving things when your not looking and tapping you on the shoulder then running away. They should be trodden on. Hard.

Sprites - The smallest of all the Fairy Folk, never growing much more than 5cm in height, these are the only type, other than Fairies, that can fly. The most effective way to dispose of a Sprite is to pour a can of Sprite(hence the name) over it's head and then force it through the ring-pull. Keep away from the teeth, though, as they are very sharp and if you get bitten it can hurt. A lot.
