Cypress & Conroe Hurricane Season Wildlife Invasion — Wha…

Fact-Checked Last reviewed: June 13, 2026

Hook Section

Last month, a homeowner in Cypress called me about raccoons in their attic. They had just come back from Hurricane Harvey and found the place trashed with droppings all over. I’ve seen this pattern repeat after every major storm in the Houston area. This guide is for homeowners in Cypress, Conroe, The Woodlands, Spring, and Tomball to help you navigate hurricane season wildlife invasions.

Roof Rats Displaced by Flooding

Heavy rains flood ground burrows and push roof rats to higher ground—attics, eaves, and wall voids. Your attic becomes prime real estate for these critters. In my territory, I’ve seen this pattern repeat after every major storm in the Houston area.

  • Roof rats are excellent swimmers but they don’t want to stay in flooded burrows.
  • Your attic becomes their new home, especially if you have any gaps or entry points.

Raccoon Attic Invasion Post-Storm

Storm damage creates entry points. Wind tears off soffit vents, loosens flashing, breaks vent covers. A raccoon only needs a 4-inch gap. After Hurricane Harvey, I ran raccoon calls non-stop from Cypress to Conroe for 3 weeks straight.

  • Raccoons are looking for safe den sites and will exploit any opening.
  • Mother raccoons with babies often look for new dens after a storm, making your attic their next home.

Snake Displacement

Flooding pushes snakes out of their normal habitat. They seek dry ground—under houses, in garages, or pool equipment areas. Most displaced snakes are non-venomous water snakes and rat snakes, but homeowners can’t tell the difference.

  • Assume it’s venomous until proven otherwise.
  • I always tell people to call a professional if they see something moving in their garage or crawl space.

Opossum & Armadillo Flood Seekers

These guys are less aggressive invaders but heavy rain floods their normal shelter. They’ll shelter under decks, in crawl spaces, and under sheds.

  • They usually seek temporary refuge due to flooding.
  • While they’re not as destructive as raccoons or rats, they can still do damage while there.

What Homeowners Get Wrong

Many homeowners assume that if they wait a few days, the wildlife will leave on its own. In my experience, this is rarely true. Snakes and raccoons are persistent and will stay until you address their entry points.

  • Snakes can be very tricky to remove without proper equipment.
  • Raccoons will likely return if you don’t seal off all entry points.

When to Call a Professional

Here’s the deal… when it comes to wildlife in your home, calling a professional today is often better than waiting. Emergency wildlife services can cost anywhere from $250-$800+ depending on the severity and type of animal.

  • Roof rats and raccoons may require more extensive trapping or exclusion methods.
  • Snakes need special handling to ensure they’re removed safely and humanely.

Pre-Storm Inspection Checklist for Homeowners in These Areas

Before the next big storm, make sure you’ve got these things covered:

  • Inspect your roof and gutters for any damage or gaps.
  • Check under decks and sheds for potential shelter spots.
  • Seal off any soffit vents, flashing, and other entry points.
