Finding Opossums in Attics Opossums are skilled climbers. The pests easily scale overhanging tree branches or power lines and gain access to rooftops. From there, they exploit weaknesses to gain entry in to attics. Damage and Problems Residents should be wary of having an opossum in the attic for many reasons. First, the pests' menacing, rat-like appearance makes for a frightening surprise when they are discovered. The pests also reproduce quickly. Females can carry two litters per year and give birth to about nine young at a time. Opossums in attic spaces also keep residents awake by creating loud scratching sounds at night. They chew away at insulation and can create fire hazards by gnawing through electrical wires. In addition, opossums can introduce ticks, lice, and fleas into the attic and the rest of the house. Furthermore, opossums are vectors for the following parasites: Mites - These microscopic pests burrow under the skin, causing itchy rashes. Roundworms - Larvae travel through the nervous system, liver, and lungs, causing fever or the enlarging of internal organs. Flukes - These pests live in the abdominal cavity and intestinal walls, where they reach maturity and lay eggs. Tapeworms - Common issues caused by tapeworms include digestive problems and abdominal pain, while more serious cases result in seizures or muscle damage. Opossums in the attic may also carry fungal, bacterial, or viral diseases like leptospirosis and coccidiosis. Exclusion To drive away opossums in the attic, eliminate all food sources. Secure garbage can lids tightly, and tie down trash bins to prevent them from being tipped over. Water and food dishes intended for pets must be brought indoors nightly, and bird feeders should be installed on tall metal poles.
