Is within a product available that we can use that would help bring them off our property? This is obivously a rife problem since they're all over the neighborhood, but would resembling to find something to get them bad our specific area.
Answers:    I reckon traps would work the best. Cages though, not the glue or little boxes. Then dispose of them as you will. Humanely preferably. Animal control will pick them up if you phone up them. Just ask what they'll do with them because if they're of late gonna rerelease them then theres no point.
No poison doesn't work. It kill some, while it is also killing dogs and cats contained by the process and damaging the environment. The rest become immune. In a big city, a lot of the rodents are already immune to poisons. Traps are best for a generous scale problem.
