How to secure a trap

[BFG Central]

There are all sorts of methods for traps and snares.

What animal are you planning to catch?

The main thing for fixing in the soil is the surface area of the ground peg.
If your going for something bigger than a rabbit then look at using a dog tether http://www.ebay.co.uk/itm/CORKSCREW-GROU..._Steamers_

Or they make a ground stake that opens up at the bottom once its driven into the ground. A short tug upwards opens the hook at the bottom of the metal rod.

Regarding surface area think along the lines of a square pen.
Even better are the orange tent pegs you get from the £1 shops.
The spike is actually a cross so the surface area is massive.
