Some suggest mothballs as a deterrent for iguanas, but they are ineffective and harmful. Mothballs contain chemicals like naphthalene or paradichlorobenzene, which are toxic to humans and animals, including iguanas. The fumes can cause respiratory problems, skin irritation, and other health issues. Moreover, using mothballs outdoors is not recommended, as they contaminate soil and water sources.

Identifying the specific animal running on your roof at night can be challenging without direct observation. Common nocturnal roof visitors include raccoons, squirrels, opossums, and rats. Raccoons are bigger and can create heavy thumping sounds. Squirrels are agile and may produce rapid scurrying noises. Opossums tend to move stealthily with less noise. Rats can make scratching or gnawing sounds. To determine the culprit, look for signs like footprints, droppings, or damaged areas near the roof. For accurate identification, consult a pest control professional or set up wildlife cameras near potential entry points.

Many people only see armadillos at night because the closer the animals are to the city, the more they stay in their burrows during the day to avoid noise. More rural armadillos are more likely to come out during the day when they can warm up in the sunlight and avoid predation by owls and cougars.

The truth is, there really is no such thing as a 100% deer-proof plant. Deer will decimate even the prickliest flora if they’re hungry enough. However, there are plenty of beautiful plants that deer don’t necessarily enjoy. These include thistles, wisteria vines, sword ferns, and beautyberries.

Deer are herbivores, and they love vegetable gardens as much as Peter Rabbit. If you don’t want to fence in your entire property, consider creating an attractive raised-bed veggie garden with mesh fencing around it to keep out deer and other critters.
