Depending on the number of raccoons inside the attic there will almost always be bathroom areas the raccoons use, and this is addressed by cleaning out the attic. Some people choose to get all insulation removed, attic sanitized, and replace the insulation. Others simply request the wildlife control company manually remove the waste only, and leave the insulation alone. Raccoon waste is hazardous because it can contain raccoon round worm eggs & parasites. These contaminates can potentially be spread around in the insulation when the raccoons burrow through it. Raccoons damage on the exterior is also a concern. Raccoons will destroy soffits, dormers, drip edge's, shingles, attic vents, gable end vents, and whatever else they can get their grubby little hands on. Most wildlife control companies can provide the services of animal proofing the holes where the raccoons had gained entry. This is highly specialized work and it takes a lot of background experience and training to be able to provide clients true professional raccoon removal services. You want to find a company that can solve all of your problems associated with raccoon infestation & damage, not simply trapping the raccoons and removing them. The wildlife removal technician should thoroughly inspect the attic space and provide digital analysis of the damage the raccoons have caused. Some work occasionally needs to be subbed out to another home improvement company because not all wildlife removal businesses have the necessary materials to completely restore your home. However they should be able to provide waste removal from the attic whenever requested. Below I provide pictures of what raccoon damage typically looks like. There is always a high damage risk with raccoons in the attic.
