Summary: If you're still seeing roaches after spraying, cleaning, and trying everything the hardware store sells, read this to find out what stops them for good.

Home & Pest Advisor

Reason 01

Most people think roaches are a cleanliness problem.

They're not.

The roaches crawling across your counter at night are scouts.

They're just the visible tip of a colony that's nesting deep inside your walls, under your floorboards, and behind your appliances.

For every one roach you see, there are anywhere from 200 to 800 hiding nearby.

Reason 02

Products like Raid and Hot Shot work exactly the way they're designed to.

They just kill the roach that walks through the spray zone.

But you know what?

That roach never makes it back to the colony.

There's no contamination spreading through the nest. 

Just one dead roach, and 500 more that never came near your spray.

Over time, the survivors get cautious and learn to avoid treated areas. 

Some species even develop a chemical resistance to common insecticides.

Reason 03

If one apartment has roaches, every apartment in that building is gonna get them no matter how clean you keep things.

It's just basic building biology. 

Roaches travel through shared wall voids, plumbing lines, and ventilation shafts. 

This means your unit can be spotless as a NASA cleanroom and you'll still get them from the neighbor two doors down.

The landlord sprays, the roaches scatter into the walls and come back after two weeks.

That cycle doesn't end until someone eliminates the colony.

Reason 04

Roach motels trap individuals.

Boric acid powder sits and waits, and roaches that have been around long enough have learned to walk around it.

Diatomaceous earth works on soft-bodied insects, but roaches have a hardened exoskeleton and can develop behavioral avoidance fast.

Sticky traps just give you a body count, not a solution.

Every one of these addresses what you can see, not what's breeding in your walls. 

Reason 05

This is the one nobody talks about.

Professional exterminator visits run $150–$300 per treatment.

Most apartment residents can tell that it worked for three weeks, then they came back worse than before.

Sprays have a residual window of a few days to a couple weeks.

The moment that chemical barrier fades, re-infestation starts.

A few survivors hiding deep in the building re-establish the colony faster than most people expect.
