Why this matters in LA (2025)

Los Angeles continues to report flea-borne typhus activity and maintains robust monitoring for rodent issues around homes and businesses. California and LA County health agencies publish ongoing guidance because rats and their fleas/urine can spread disease—and improper cleanup increases risk.

Quick action: If you see droppings, nests, or live activity, book a free inspection with Rodent Control in Los Angeles (24/7 response). For small indoor sightings, see our Mice Control.

Diseases tied to rats in Los Angeles

Flea-borne typhus (a.k.a. murine typhus)

• Official info: California Dept. of Public Health (CDPH) and LA County DPH detail transmission, symptoms, and prevention.
• What it is: Illness caused by Rickettsia typhi, spread by infected fleas that often feed on rodents, cats, dogs, or opossums.
• Where it appears: Endemic in parts of Los Angeles County (present year-round with seasonal peaks).
• Symptoms & care: Fever, headache, body aches; seek medical care—antibiotics are effective when started promptly.

Leptospirosis

• What it is: Bacterial disease spread through contact with urine of infected animals (including rodents); risk rises with contaminated water/soil.
• Why it matters here: Crawl spaces, alleys, and flood-prone spots can harbor contamination.
• Official info & prevention: CDC provides current guidance and clinical overview.

Cut exposure to fleas and rodent urine; control and exclude rodents to break transmission routes.

Food facilities: how vermin cause closures

Rodent activity (droppings, live rats/mice, contaminated surfaces) can trigger vermin closures for restaurants, markets, and food warehouses. LA County publishes inspection results publicly—owners and managers should monitor their listings and fix issues before they escalate.

What to do if you find signs (safe cleanup)

Do not dry sweep or vacuum droppings. That can aerosolize particles. Follow CDC cleanup steps: ventilate, wet disinfect, and bag waste safely.

Rapid checklist (CDC-aligned):

• Ventilate area ~30 minutes (windows/doors open).
• Wear rubber/plastic gloves.
• Spray urine/droppings/nests with bleach solution (1:10) or EPA-registered disinfectant until very wet; soak 5–10 minutes.
• Wipe with paper towels; double-bag waste; discard in covered bin.
• Disinfect hard surfaces; wash gloved hands, then wash hands again after removing gloves.

Rodent Control Los Angeles: Our 5-Step Process

It’s not bait-and-wait. It’s a closed loop: Inspect → Exclude → Sanitation Coaching → Targeted Removal → Verify & Prevent.
This aligns with Integrated Pest Management (IPM) best practices from university and public-health sources. Mice Control

Step 1 — Diagnose (Full-Property Inspection)

• Attic-to-alley survey: rooflines, eaves, vents, conduits, door thresholds, crawl spaces.
• Identify species (roof rat vs Norway rat) and activity level.
• Immediate safety notes if we find gnawed wiring or contaminated insulation.
• Deliverable: a simple report with prioritized fixes and a service plan.

Step 2 — Exclude (Seal Every ¼″+ Gap)

• ¼″ galvanized hardware cloth on vents/soffits; steel or copper mesh + mortar/metal flashing around pipes and conduits.
• Door sweeps/brush seals for garages and service doors; adjust thresholds until no light shows.
• Trim palms/vines clear of roof and eaves.
• Result: rodents cannot re-enter while we remove the ones inside.

Step 3 — Sanitation Coaching (Fast Wins that Matter)

• Lock bin lids, keep pads under grease containers, elevate cardboard and storage.
• Use city tools: Bulky Item Pickup and MyLA311 to keep alleys clean.
• Why: less food + fewer harborage sites = faster results.

Step 4 — Targeted Removal (Safe & Compliant)

• Covered snap traps and locked stations placed along runways—no open devices.
• Strategy tailored to California’s current restrictions on certain rodenticides; we emphasize exclusion + devices first.
• Pet- and kid-aware placements with clear maps.

Step 5 — Verify & Prevent (Follow-Ups You Can Trust)

• Photo-verified exclusion points, capture logs, odor-neutralizing clean-ups as needed.
• Re-inspection after weather or construction.
• Optional monitoring plan for restaurants, multi-unit, warehouses.
