What Do Roaches Eat?

If you’ve spotted a cockroach in your Sacramento or Northern California home, one question usually comes next:

“What are they finding to eat in here?”

The frustrating answer? Almost anything.

Cockroaches are expert scavengers, which is why they thrive in kitchens, bathrooms, garages, and even outdoor spaces around homes in Northern California. Understanding what roaches eat — and why they’re attracted to your property — is a key step toward stopping an infestation before it grows.

Common Foods That Attract Cockroaches in Sacramento Homes

Starches & Sugars (Their Favorite Targets)

Roaches eat carbohydrates and sugar-rich foods, including:

Even crumbs tucked behind appliances are enough to sustain them.

Proteins & Fats

Grease and protein sources are another major attraction:

This is why roaches are commonly found behind stoves and refrigerators.

Pet Food (A Hidden Problem)

Pet food is one of the most overlooked roach attractants:

In many Northern California homes, pet food alone can support an ongoing roach problem.

Non-Food Items Cockroaches Will Eat

When food is limited, roaches don’t leave — they adapt.

They’ll feed on:

This explains why roaches can survive even in homes that appear clean.

Outdoor Food Sources That Drive Roaches Indoors

Our climate allows roaches to thrive outdoors much of the year. Common outdoor attractants include:

When outdoor food sources become scarce or when weather conditions fluctuate, roaches move indoors.

The Real Reason Roaches Are So Hard to Control

Cockroaches aren’t picky eaters. They’re omnivores with survival instincts that allow them to feed on food scraps, household materials, trash, and even non-food items when necessary.

That adaptability is exactly why infestations can linger and why DIY treatments often fall short without professional help.

How to Make Your Home Less Appealing to Roaches

Sacramento and Northern California’s climate can encourage roach activity year-round. These steps help break their food chain and protect your home:

1. Keep Surfaces Clean
Wipe up crumbs, grease, and spills on counters, floors, and tables. Roaches are opportunists—they thrive in areas where food residues accumulate.

2. Store Food Properly
Use airtight containers for cereal, pasta, snacks, and pet food. This simple step drastically reduces roaches’ access to meals.

3. Manage Trash
Use trash bins with tight-fitting lids, line them with sturdy bags, and take out garbage regularly. We also recommend cleaning bins periodically to eliminate lingering food odors.

4. Mind Pet Food
Don’t leave pet food out overnight. Clean bowls after feeding and store dry kibble in sealed containers.

5. Declutter Regularly
Roaches love hiding among clutter. Keep cabinets, closets, and under furniture clean and organized.

6. Inspect & Seal Food Storage Areas
Check pantries, shelves, and cabinets for cracks or gaps. Use caulk or weatherstripping to block entry points.

7. Clean Appliances
Roaches often hide behind stoves, refrigerators, and toasters. Pull appliances out periodically to remove crumbs and grease.

8. Watch Outdoor Areas
Keep outdoor trash bins sealed, pick up fallen fruit or birdseed, and trim plants to remove potential food sources for roaches.
