We used this product to keep mice from entering the house via the openings in the stucco. Easy to install, we learned to tape the ends when cutting to keep the bits of cut copper to a minimum. This should solve our problem, took us a few hours to place the wire, in larger, deep areas we used chicken wire AND mesh AND foam. We don't expect any more problems! Product was shipped quickly. Should also stop larger bugs like scorpions from getting in.
Remember to NOT use rodent poisons, secondary poisonings is the leading cause of raptor deaths, and raptors are what keep the rodent population down.
