Where Do Roaches Come From?

Where Do Roaches Come From?

If you’ve lived in Canby or Salem long enough, you probably know how certain pests love to make themselves at home when the rains come. 

And with Oregon’s damp climate, the question “where do roaches come from?” becomes all too relevant for local home and business owners, especially when temperatures cool and these unwanted guests start seeking out some welcome warmth indoors. 

Cockroaches are experts at sneaking into homes, and once they’re in, the battle to get rid of them can feel endless. Whether you’re seeing one skitter across your kitchen floor or noticing droppings in a dark corner, here’s what you need to know about where these pests come from, what draws them to your home, and how to keep them out for good. 

Where Do Roaches Come From in Salem and Canby?

 

Roaches aren’t picky about how they enter your home. Here are the most common ways they invade our Pacific Northwest homes:

  • Pipes and Drains: Cockroaches are great at navigating sewer systems and can crawl up pipes, making their entry through kitchen or bathroom drains. 
  • Cracks and Gaps: Tiny cracks in your walls, floors, or exterior foundation are like highways for roaches. Even small gaps around windows and doors give them the perfect entry point. 
  • Deliveries and Grocery Bags: German cockroaches, one of the most common household species, often hitch rides in grocery bags, cardboard boxes, or used furniture. 

Once inside, these pests waste no time, spreading quickly in their new homes. One female cockroach can lay up to 40 eggs in a single egg case, leading to massive infestations in mere months. 

Why Are Roaches Attracted to Oregon Homes? 

Like all pests, cockroaches thrive in environments that meet three basic needs: warmth, moisture, and food. Many homes in Canby and Salem unknowingly provide the perfect setup for an infestation. Here’s why: 

  • Moisture: Oregon’s rainy climate means many homes struggle with damp basements, leaky pipes, or poorly ventilated areas. Roaches are drawn to these humid conditions. 
  • Food Sources: Leftover crumbs, dirty dishes, and even pet food act as an open buffet for cockroaches. 
  • Cluttered Spaces: Dark, cluttered areas like garages, basements, or attics create ideal hiding and breeding spots. 

Why Are Cockroaches a Big Problem? 

Believe it or not, cockroaches actually serve an important role in nature. They break down decaying organic matter and are a valuable food source for creatures like toads, spiders, and beetles. 

 

But indoors,cockroaches can also cause real problems for homeowners. 

For one, they reproduce quickly. A single cockroach can become a full-blown infestation within weeks. Female German cockroaches can produce thousands of offspring in a matter of months. 

They also pose health concerns. Cockroaches are known to spread bacteria and allergens, exacerbating asthma and allergies, especially in children. 

Unfortunately, they’re incredibly difficult to eradicate. DIY methods like sprays often only kill visible roaches. Their nests, often hidden, require professional-grade products and strategic treatment to fully eliminate an infestation

How to Keep Cockroaches Out of Your Home 

Preventing cockroaches starts with making your home less inviting. Here are some practical tips to keep them at bay: 

  • Seal Entry Points: Inspect your home for cracks, gaps, or holes around windows, doors, and pipes. Use caulk to seal up potential entry points. 
  • Fix Leaks: Repair any leaky faucets or pipes. 
  • Declutter Your Space: Clean out cluttered areas like closets and garages where roaches can hide and breed. 
  • Keep It Clean: Wipe down counters, vacuum regularly, and ensure there are no food crumbs left exposed. Store food in airtight containers. 
  • Take Out the Trash: Dispose of garbage frequently and keep lids tightly sealed. 

One more pro tip from our team here at Kanga? Don’t forget your drains! Pouring boiling water down your kitchen and bathroom drains weekly can help deter roaches from crawling up.
