A collection device (10) is useful to scoop and bag refuse, such as pet excrement, from a surface. The device includes a handle (12) that supports a working head (30) that has an intake portion (32), a discharge portion (36) and a guide portion (34) therebetween. The working head has bag holders (70) to secure a bag (90), such as a plastic grocery bag, with a mouth engaging the discharge portion so that refuse may be introduced into the intake at an upstream end and dumped into the bag at the downstream end. The intake portion has forwardly extending tines (60). The bag holder is shown as radial posts (70) and/or a ring clamp (102). The handle may be either be a short hand grip (316) or preferably an elongate rod that permits use of the collection device while the user is standing. The working head is preferably cylindrical, but it may be flattened if desired.
