Why You See Bat Droppings but Not the Bats — and How to Get Rid of Them

If you’ve noticed small, dark pellets scattered beneath your eaves, in your attic, or on your porch, you might have a bat problem — even if you’ve never actually seen one. Bats are secretive creatures, and in Rialto and Fontana, it’s common to spot their guano (droppings) long before you ever catch a glimpse of the animal itself. At TruPest Solutions, we help homeowners understand why bats choose certain properties, the risks they bring, and the most effective ways to get rid of them.

Why You Usually See Their Poop, Not the Bat

Bats are nocturnal and prefer to stay hidden during daylight hours. They roost in dark, enclosed spaces like attics, under roof tiles, behind shutters, or inside barns and sheds. This means you’re far more likely to notice the bat droppings that accumulate beneath their roost than to see the animals themselves. Bat guano often looks like small, dark, crumbly pellets — and it’s a telltale sign you should take action.

Why Bats Hang Around Your Property

Bats aren’t trying to cause trouble — they’re simply looking for food and shelter. In the Rialto and Fontana area, bats are attracted to properties that provide:

• Abundant food sources — Bats are natural insect hunters, feeding on mosquitoes, moths, beetles, and other flying insects. A yard with a healthy insect population is basically an open invitation.

• Shelter from predators and weather — Attics, eaves, soffits, and barns offer safe, dark roosting spots.

• Nearby water — Ponds, pools, birdbaths, and irrigation systems can draw insects, which in turn draw bats.

What Bats Eat

Bats are nature’s pest control, consuming thousands of insects each night. In Southern California, their diet mainly includes:

• Mosquitoes

• Moths

• Beetles

• Flies

• Gnats

While this makes them beneficial in some ways, having them roosting on your property can create serious health hazards.

The Risks of Bats Around Your Home

• Health concerns — Bat guano can harbor fungi that cause histoplasmosis, a potentially serious lung infection.

• Structural damage — Accumulated droppings can stain and corrode surfaces.

• Parasites — Bats can carry fleas, mites, and ticks.

• Rabies risk — Although rare, bat bites can transmit rabies.

How to Get Rid of Bats and Keep Them Away

Getting rid of bats requires a careful, humane approach — and in many cases, professional help. At TruPest Solutions, we follow a proven process:

1. Inspection — We locate entry points and roosting spots in attics, rooflines, vents, and other structures.

2. Exclusion — Special one-way devices allow bats to leave but prevent them from returning.

3. Sealing entry points — We close gaps, cracks, and openings once bats are gone.

4. Guano cleanup & sanitation — Safely removing droppings and disinfecting affected areas.

5. Ongoing prevention — Regular inspections to ensure bats don’t return.

Important: Never try to trap or kill bats — it’s both dangerous and, in many cases, illegal. The safest solution is professional bat removal.
