Raccoon droppings and bird nesting material should be handled with a respirator, gloves, and sealed bags, and most homeowners in Merrimack, New Hampshire are better off paying for that part. Attic insulation contaminated by raccoon droppings should be removed by workers wearing respirators, not household masks.

Frequently Asked Questions

How do I get rid of a skunk under my deck?

Confirm the skunk is alone in Merrimack, then evict with a one-way door or trap it in a covered cage at dusk. Once it is out, a Merrimack provider trenches and buries hardware cloth around the deck perimeter. In Merrimack, New Hampshire, skunks may need a permit to trap, so ask first.

How long does wildlife removal take?

Plan on one to three weeks from inspection to final re-check for a typical Merrimack job. Removal is the short part; sealing and reinsulating takes longer. Providers in Merrimack, New Hampshire often schedule the follow-up a few weeks after sealing.

Are bird nests protected?

It depends on the bird. Federal migratory bird rules apply in New Hampshire, so a provider in Merrimack first identifies the species, then either clears the nest and installs a guard or schedules the work for after the young leave. Timing is the main effect on a Merrimack bird job.

Does homeowners insurance cover wildlife damage?

Policies vary, and the animal matters. Sudden damage from raccoons or groundhogs is often covered in Merrimack, New Hampshire, while squirrel chewing and slow contamination usually is not. Call your insurer before the work starts in Merrimack, and have the Merrimack provider itemize damage separately from removal.

How do I get rid of a groundhog?

Groundhogs in Merrimack are trapped in a cage set at the burrow entrance with fruit or vegetable bait, then the burrow system is filled and the area fenced with buried wire. Because they dig deep, Merrimack, New Hampshire providers bury mesh a foot down and bend it outward to stop re-entry under sheds.

Will the state help with a nuisance wildlife problem at my home?

Usually with information, less often with hands-on help. For Merrimack, New Hampshire the relevant figure is this: homeowners wanted guidance more than anything else: 73% of homeowners in a large northeastern Illinois metro region asked for information from the Illinois Department of Natural Resources (IDNR) in the Illinois Natural History Survey's 2000 study, a historical local finding, versus 52% wanting direct help. Local conditions in Merrimack, New Hampshire can differ from the survey population, so confirm the specifics with an on-site inspection.

Do most homeowners do anything about nuisance wildlife?

Most do, though a sizable share wait it out. The national picture, which Merrimack has no reason to escape: in the Illinois Natural History Survey's (INHS) July to October 2012 survey of homeowners in the greater metropolitan area of northeastern Illinois (reported 2013), 62% of the 830 households with a wildlife problem said they had done something about it.
