Rabbits face a range of formidable adversaries in rural and suburban areas. Natural predators such as hawks, foxes, bobcats, raccoons, coyotes, and weasels pose significant threats to their survival. These skilled hunters target bunnies for food, contributing to regulating rabbit populations. Outdoor housepets can be enemies, too, particularly dogs and cats. And loud little humans playing in your yard make great rabbit deterrents, too.

Yes, it’s possible for bats in your attic to find a way into your living spaces. Until you can properly remove the bats, the best course of action is to keep the attic doors closed and any holes sealed. Evidence suggests bats follow the airflow in your home, so they may try escaping from the attic to other parts of the house.

Both spikes and loose nets can be installed over nest sites to prevent the bird from returning, but nets are not a humane option since birds and other wildlife can get tangled in them. 

Spikes are a humane alternative that deter nesting without harming the birds. In small areas, like vents, a very fine mesh net can be installed to prevent the bird from returning. These nets don't generally pose a risk to the birds.

The lifespan of a bird's nest depends on the species. The building process can take from two days to three weeks. Once built, the nesting period for baby birds can last from two to ten weeks before they leave the nest. While most young birds are ready in two to six weeks, some predatory species may need up to two and a half months. Some species nest four to five times per year, so a nest could remain in use for several months. For specific information about a particular nest's longevity, it is best to consult a wildlife professional.
