How to Identify the Most Common Household Pests in Florida (Before an Infestation Starts)

Florida’s warm, humid climate makes it one of the most pest-active states in the country. Many infestations begin unnoticed and grow quietly until damage or health risks become obvious. Early identification is the key to preventing costly problems.

Common Signs of Pest Activity

Most pests leave behind clues before you ever see them directly. These signs typically fall into four categories: visual sightings, droppings, sounds, and physical damage.

Roaches

• Visual signs: Live or dead roaches, especially at night or when lights turn on

• Droppings: Small black specks resembling ground pepper

• Other clues: Musty odors, shed skins, egg cases in cabinets or behind appliances

Ants

• Visual signs: Lines or clusters of ants along walls, countertops, or baseboards

• Droppings: Fine debris near entry points or nests

• Other clues: Small soil piles near cracks, windows, or pavers

Rodents (Rats and Mice)

• Visual signs: Sightings at night, grease marks along walls

• Droppings: Small, dark pellets in attics, garages, or pantries

• Sounds: Scratching or scurrying in walls or ceilings

• Damage: Chewed wires, insulation, or stored food

Termites

• Visual signs: Mud tubes along foundations or walls

• Droppings: Small piles of pellet-like frass (drywood termites)

• Damage: Hollow-sounding wood, warped doors, bubbling paint

Silverfish

• Visual signs: Fast-moving, silver insects in bathrooms or kitchens

• Damage: Holes in paper, books, wallpaper, or clothing

• Other clues: Typically found in damp, dark areas

Why Early Detection Matters

Catching pest activity early allows for targeted treatment, reduced damage, and lower costs. Many pests multiply rapidly in Florida conditions, making delays expensive and disruptive.
