Droppings from cockroaches, squirrels, mice, bats, and birds can resemble rat poop, making it easy to confuse one for another. Mouse droppings are smaller and more pointed, cockroach droppings resemble tiny black specks or ground pepper, and bat guano can look similar but usually crumbles into powder. Bird droppings sometimes have a similar shape, but often include white uric acid deposits. If in doubt, it’s best to consult a pest control professional for proper identification and removal.

Skunks spray as a defense mechanism to ward off predators. The active ingredient in their sulfurous, oily musk is n-butyl mercaptan, which evaporates into a powerful and smelly gas. Once the spray hits the skunk’s target, the stench can linger for days, and water and common cleaning kits aren’t enough to wash it away.

If you happen upon a skunk in your yard, try to back away slowly to reduce the chance of them aiming at you. Encouragingly, they don’t use their weapon casually, as it can take up to 10 days for their life-saving weaponry to refill. Paw stamping, hissing, lifting their tail, and arching their back are early signs they feel trapped or under threat and that it’s time to make a careful retreat.

You’ll find groundhogs are most active during the morning hours and late afternoon, but they want to avoid humans at all costs. If you do set a trap, you can set it out the night before so it’s waiting on them the next morning, and try to remove any human scent when setting it out.

Scent deterrents like ammonia, vinegar, mothballs, and pepper can help keep coyotes away, but these are best used in tandem with other preventative measures. Remember that ammonia and vinegar can kill your plants and/or grass, so it’s best to soak rags in these substances or spray them on hardscaped areas to avoid damaging your landscape.
