hi Roger
nutella and cooking oil,bread crumbs,blended cat food, blended mackerel,Peanut butter.any thing that has a strong Obnoxious!! smell (Steve/Dave Graham)
and any thing that is sweet! definitely not the named above!
but to be fair if there is a food source on your permission,just hide up about 30yds your zero as i remember your using .22 and you will get every one which comes out!
Ref payment! you can take it as a donation towards fuel, i have also looked into this to.
i am sure its about £150.00 per year for insurance ?,so @ £5.00 a rat it wont be long before you get 30 rats
