Why Bathrooms Attract Pests

Bathrooms provide everything pests need to survive:

  • Moisture: Leaky faucets, standing water, and damp tiles attract cockroaches and other pests.
  • Dark, hidden spaces: Cabinets, behind toilets, under sinks, and around drains are perfect hiding spots for pests. Even damp, dirty towels and laundry on the floor can serve as hiding spots.
  • Food sources: Soap residue, toothpaste, and even hair can attract insects over time.

Arizona’s dry climate makes bathrooms especially appealing to moisture-loving pests.

Common Bathroom Pests in Southern Arizona

Cockroaches

Often found near sinks, tubs, and drains. Cockroaches thrive in moisture and can spread bacteria if left unchecked.

Ants

Species like odorous house ants enter bathrooms in search of water. They often travel along plumbing lines or baseboards.

Silverfish

Small, fast-moving insects that feed on paper, glue, or soap residue. Silverfish prefer damp, dark areas.

Scorpions

Scorpions, and particularly Arizona bark scorpions, are attracted to moisture and dark hiding spots, which makes bathrooms a potential refuge.

Centipedes or Millipedes

Moisture-loving arthropods occasionally wander indoors, especially during the monsoon season.

Signs You May Have a Bathroom Infestation

Look for these early warning signs:

  • Live insects near sinks, drains, or under cabinets
  • Droppings, egg cases, or shed skins
  • Musty, oily odors
  • Small smear marks along walls or baseboards
  • Unexplained damage to paper products or bathroom items

Simple Bathroom Pest Prevention Tips

Keeping your bathroom pest-free doesn’t have to be complicated. We recommend:

  • Fixing leaks immediately: Even small drips can attract multiple pests.
  • Keeping surfaces dry: Wipe down sinks, tubs, counters, and floors after use.
  • Sealing gaps and cracks: Inspect around pipes, baseboards, and vents to block entry points.
  • Decluttering regularly: Fewer hiding spaces mean fewer pests.
  • Disposing of trash daily: Soap wrappers, hair, and other waste can invite pests.
  • Cleaning drains regularly: Remove debris to prevent drain flies and roach breeding.
