No, not most houses globally, but cockroaches are extremely common, especially in urban areas, with studies showing 78-98% of urban homes can host them, even if unseen, as they are nocturnal and great at hiding, needing only food, water, and shelter found in most homes. So, while not every single house has an infestation, it's very common for them to be present, often in small numbers, hiding in walls or plumbing, especially in multi-family dwellings.

Does every home have roaches?

It's a common myth that every house has cockroaches. However, that's not entirely true. Not every home will have a visible roach problem, especially if it's well-maintained and free from food, water, and shelter sources for them.

How normal is it to have roaches?

Finding roaches in your home is not unusual, especially in regions with high humidity and warmth, like Florida. These resilient pests are naturally drawn to shelter and food sources, and they can easily enter homes through tiny gaps or when seeking refuge from extreme weather conditions.

Why am I getting roaches when my house is clean?

You have roaches in your clean house because they're after minimal water, food (even crumbs, pet food, or soap!), shelter, and they can easily hitchhike in via groceries or used items, exploiting tiny cracks or plumbing pipes for entry, especially in multi-unit dwellings where neighbors also have them. A spotless home doesn't eliminate their basic needs or entry points like drains, gaps, and vents.

Why shouldn't you squish cockroaches?

You shouldn't squish a cockroach because it spreads harmful bacteria, allergens, and pathogens (like Salmonella and Staphylococcus) into your environment, potentially causing illness or asthma, and the fluids can stain surfaces. Crushing them also releases a chemical signal (oleic acid) that attracts other roaches, essentially advertising an all-you-can-eat buffet and worsening the infestation.

What is roaches' biggest weakness?

A cockroach's biggest weakness is its dependency on food, water, and shelter; disrupting these needs, especially moisture, is key, as they can only survive about a week without water, making leaky pipes and damp areas critical vulnerabilities to eliminate for effective control. While resilient, they also struggle in clean, dry, well-lit spaces and dislike certain smells like citrus, lavender, or cucumber, but their fundamental survival triangle (food, water, harborage) is their primary Achilles' heel.
 

What draws roaches out of hiding?

Cockroaches are commonly attracted to homes by food, moisture, and shelter. They seek out food sources like crumbs, uncovered food, dirty dishes, and garbage, while also being drawn to unsealed pantry items.

What surfaces can roaches not crawl on?

Roaches struggle to climb extremely smooth, slippery surfaces like glass, porcelain, polished metal, granite, and marble, and barriers made from Teflon/silicone tape, petroleum jelly, or fine powders (like diatomaceous earth) are effective at stopping them because they can't get a grip. Rough textures or any imperfections, even on seemingly smooth plastic, can provide footholds, so perfect smoothness is key for a barrier.
