Robert from Belington, Wv 26250 writes,

Excrement dropping appeared in the basement wall under an exterior vent. I do not know what they are from....

Excrement droppings were found on the painted cinder block wall 4' off the ground, just below an unopened exterior vent. There are approximately 50 pieces, each being between 3/4 to 1 inch in length, and very thin, approximately .7mm. The tips of each end are sharp, and not blunt. There are no droppings on the floor, and the droppings appear to adhere to the wall. On the wall above, below, and to each side, I put up 8"X12" catchmaster glue boards, and on the vent opening, I lined the ledge with mice snap traps. I have caught nothing on the glue boards and the mice traps have not been disturbed in over a week. I can supply a picture of the dropping on the wall with a dime held up to give a relevant comparison. Any help you give me would be greatly appreciated. Thank you for your time and effort in this endeavor.


The droppings that you are describing sound like roof Rat Droppings. Roof Rat Droppings are described as "at least 3/4 inch long with pointed ends". Roof rats cannot be caught with mouse glueboards or mouse snap traps. We do carry Rat Glue Board Traps and Rat Snap Traps that would be more suited to this job. Baiting the traps with canned cat food or tuna fish, nuts, small pieces of floss or cotton balls (nesting materials) may also help to draw this species of rat into the traps. Please let us know if you have any other questions.
