Well, we left the traps out for another week, checking them several times a day.
As of last night, we have caught a grand total of 23 chipmunks, 1 mole, and 2 raccoons. (The raccoons both took a trip to the country and were released.) Sometimes, my husband will empty the trap and go inside for a few minutes only to come back out and find another tennant in the trap again. It's absolutely crazy.
We're pretty sure that we've eliminated the ones that were living in our yard and are now dealing with new ones coming in from our neighbors. It's time to seal up the holes on our property and apply some predator urine to mark the boundaries of our lot to keep new chipmunks from entering.
The crazy thing about all of this is that we don't live in the country. We live in the suburbs. Our neighbors' yards are 6-10" from the sides of our house. Why do we have so much wildlife all of a sudden?!?
