Pest Control Research sells a range of excelent kill traps as listed below. Kill traps have an advantage over leg-hold traps because they are not required by New Zealand law to be checked on a daily basis. This means the traps can be left set for several days or weeks which increases the time available for an animal to be caught and drastically reduces the time required to check traps. Portable kill traps are a popular option with the Department of Conservation and possum control contractors because of this time-saving advantage.
