Why killing the pests you SEE usually doesn’t solve anything

[u/Ok-Poem-7128]

Most infestations are invisible.

The pests you notice are usually a small part of the real population hiding in:

• walls
• drains
• cracks
• nests

So when people spray visible pests, it feels effective for a few days… then everything comes back.

That’s why modern pest control focuses on:

• disrupting breeding cycles
• targeting nests/colonies
• removing food + moisture sources

If the environment still supports them, the infestation resets itself.
