Check the number of rabbits to gauge how many rabbit traps to purchase.
As rule of thumb the size of the rabbit population can be easily obtained by counting rabbits at the site of damage, during the daytime in heavily infested areas or at night, using a spotlight. Where feasible, the number
of rabbit traps used should be one half of the total number of rabbits counted. In glasshouses and allotments where only a few rabbits can cause considerable damage, a minimum of 6 rabbit traps should be used.
