We have a hudge problem with rats at the moment. I have tried every thing Bait shachets, Bait blocks, Snap traps, Live traps and a bath tub full of water (only got three that way). All except sticky glue traps. What are they, are they humane, do you have to kill the rats or do they die humanly. Last night counted 19 different ones. We lock up the chook food but for some reason they still come. Urgent advise and thanks ahead
