Yes, Cockroaches Can Survive Winter!

 In Cockroaches

A lot of people think of winter as a restful, peaceful escape from most of the pests that plague the Pacific NW. In some respects–they’re right! We don’t deal with wasps in the winter–and everyone knows that cockroaches die in the winter, right?

Wrong! Cockroaches are hardy, small, and willing to do whatever it takes to survive. These pests have existed on earth for millions of years, and have been found still living at nuclear test sites. Cockroaches aren’t dying out anytime soon. So why worry in winter?

Cockroaches Start Moving Inside During Fall

Cockroaches like it warm and moist. When temperatures outside drop down below 60 or 70 degrees, they start to get a little nervous. The beginning of September is typically a busy time for pest control all around–box elder bugs, rodents, and ants are all on the move, trying to find food and shelter. Cockroaches are looking for a winter home too–but they’re just a little sneakier about it:

  • Roaches can fit into very small spaces and cracks.
    • Time to check the sealant and caulking around your home!
  • Cockroaches can live for a long time without food.
    • If they get into your home, they can live in your walls–without you knowing or suspecting–for months.
    • They can’t live for very long without water. It depends on the species, but a cockroach will typically die without water after a week.
  • Cockroaches make it work.
    • Again, roaches have survived nuclear testing sites.
    • If you spray for them, they’re probably just going to move to the next room or apartment unit.

Do Cockroaches Hibernate?

They don’t hibernate, and will remain active as long as temperatures are above freezing. They obviously prefer a warmer and more humid environment, but they will survive–unless it’s below freezing. Cockroaches will go into a dormant state in freezing temperatures, but even that won’t kill them unless it lasts a week or more.

How to Get Rid of Cockroaches in Winter

The first and most crucial step toward getting rid of cockroaches is to eliminate their comfort zone. If your home supplies roaches with food, water, and shelter–they’re not going to leave!

  1. Clean and sanitize every surface: floors, walls, counters, pantries, and anything else that has touched food at any time.
  2. Make sure all of your food is sealed in hard plastic containers.
  3. Check for plumbing leaks through the entire home. If they find even a spare drop, the roaches can survive.
  4. Seal up cracks and holes in every part of the house–especially holes between floors, leading into walls, and cracks around window sills.

This is only half of the battle. You’ll need to hit the cockroach infestation with some significant pest control to get rid of them for good. Whatever you do–do not spray. It will just move them into another part of the home.
