How to Eliminate Cockroaches Inside When It’s Cold Outside

If you live in the northern climates and swear you see an uptick in cockroach infestations during the colder months, you’re not alone. Like other animal species, cockroaches go where the surroundings are temperate, preferring a warm and humid climate.

But cockroaches are nothing if not highly adaptable. After all, they readily survived the ice age. So it’s not just falling temperatures that drive cockroaches inside. The dry winter months also produce a scarcity of resources, which sends cockroaches indoors foraging for food and water.

That’s why it’s important to maintain a pest control strategy year-round. Your strategy should focus on denying cockroaches the three things they need to survive: warm shelter, food and water.

Here are five tips that will help stop a cockroach infestation during the cold months:

  1. Eliminate clutter around the house: Don’t allow piles of newspapers, empty boxes, unused paper bags and other piles of clutter to sit around. Disposing of clutter helps eliminate places that could hide and harbor roaches.
  2. Don’t provide sources of water: Roaches can live for up to two months without food. But they need water much more frequently to survive. That’s why it’s critical to repair leaky pipes and clean up pools of standing water. 
  3. Remove food sources: Eliminate food sources around the house. Don’t leave dirty dishes in the sink, sweep routinely after cooking, and never leave food or crumbs on countertops. Any leftover food should be stored in airtight containers.
  4. Deny access to the house: Cockroaches can squirm through the smallest openings. Be sure to seal gaps around pipes with flexible caulk, as well as patch any cracks and crevices you find around the house. 
  5. Use a long-term cockroach insecticide: Spray insecticides are contact killers – only killing the cockroaches you see, not the ones you don’t. To have total cockroach control, you need a killing agent like Combat that targets roaches at their source. Roaches readily ingest Combat Baits and Gels and bring it back to the nest where their sputum, feces and carcasses spread the poison to the rest of the nest–killing the infestation in an exponential domino-like effect.
