Ultra Power Traps from The Big Cheese® are performance tested to ensure effective control of rats – just like the traps that professionals use. Ultra Power Traps are also easy to set and supplied baited ready-to-use. Simply remove the bait cover and squeeze the trap to set – the traps are guaranteed to kill rats, or your money back. For best results place the two traps 4-5 metres apart where rats are active. Heavy infestations may require more traps.
