DIY GUIDE TO RODENT REMOVAL

Before You Start: Know When to Call a Professional

Before attempting any DIY rodent removal, review the situations below. If any of these apply to your home, skip the DIY steps and contact HAWX Pest Control directly for a professional assessment.

Section 2: Health Hazards of Rodents in Your Home & Attic

Understanding the health risks posed by rodents is essential before you begin any removal efforts. Rodents are among the most prolific disease carriers in the animal kingdom, and many of these diseases can be contracted simply by breathing in contaminated air.

2.1 Diseases Transmitted by Rodents

2.2 Special Danger: Attic Infestations

Attics present a uniquely dangerous environment for DIY rodent removal. Due to limited airflow, droppings and urine accumulate over time, creating extremely high concentrations of aerosolized pathogens. When insulation soaked with rodent waste is disturbed — by vacuuming, sweeping, or simply walking through — microscopic virus particles become airborne and can be inhaled instantly.

2.3 Secondary Health Hazards

Section 4: Essential PPE & Health Safety Protocols

This is the most critical section of this guide. Proper personal protective equipment (PPE) and sanitation procedures are NOT optional. These protocols are the difference between a safe DIY project and a potentially fatal exposure to zoonotic disease.

4.1 Required Personal Protective Equipment (PPE)

Assemble ALL of the following items before beginning any inspection, removal, or cleaning activity:

4.2 PPE Donning & Doffing Procedure

Contamination most commonly occurs during removal of PPE. Follow these procedures carefully every time.

Section 5: Step-by-Step Rodent Removal Process

With your PPE assembled and health protocols understood, you are ready to begin the removal process. Work methodically through each phase.

Phase 1: Ventilate the Area

Before entering any enclosed space with evidence of rodent activity, open windows and doors and allow the space to ventilate with fresh air for a minimum of 30 minutes. This allows airborne particles to settle and disperses some pathogen concentration. Do NOT use fans that blow air toward you or back into living spaces.

Phase 2: Inspection & Mapping

Wearing full PPE, systematically inspect the entire affected area. Document your findings:

• Location and approximate quantity of all droppings
• Nesting site locations
• Gnaw marks and entry/exit points
• Food sources that may be attracting rodents
• Areas of potential re-entry from outside

Phase 3: Trapping Strategy

HAWX recommends snap traps as the primary removal method. They are effective, inexpensive, and do not pose the secondary poisoning risks of rodenticide baits (which can harm children, pets, and wildlife). Glue traps are discouraged due to animal welfare concerns and risk of escape with pathogen spread.

Rodenticide Bait Safety Warning

Second-generation anticoagulant rodenticides (SGARs) such as brodifacoum are extremely dangerous and are BANNED for residential use in many states. They cause secondary poisoning in owls, hawks, foxes, and household pets that eat poisoned rodents.

If you choose to use any bait products, use ONLY first-generation baits (warfarin, chlorophacinone) in tamper-resistant bait stations, placed ONLY in locations completely inaccessible to children and non-target animals.

HAWX strongly recommends mechanical snap traps for DIY use over any rodenticide product.

Trap Placement Guidelines:

• Place traps perpendicular to walls with the trigger end touching the wall — rodents run along walls and will trigger the trap naturally.
• Set traps every 2-3 feet along active runways (areas with droppings or grease marks).
• Bait with peanut butter, chocolate, nesting materials (cotton balls), or dried fruit. Use a pea-sized amount only — too much bait can be taken without triggering the trap.
• For rats: Pre-bait unset traps for 2-3 days first. Rats are highly neophobic and will avoid new objects until comfortable. Set the traps only after they have been feeding.
• Check and reset traps daily. Leaving a dead rodent in a trap for more than 24 hours significantly increases disease and fly/insect risk.
• Place a minimum of 6-12 traps for a small mouse infestation; 3-6 large traps for rats.

Phase 4: Safe Disposal of Dead Rodents

1. Put on full PPE before approaching any trap or dead rodent.
2. Spray the dead rodent and surrounding area generously with an EPA-registered disinfectant or a freshly mixed 1:10 bleach solution (1 part bleach to 10 parts water). Allow to soak for 5 full minutes.
3. Pick up the rodent with a paper towel or disposable rag — do NOT pick it up with bare hands even while gloved.
4. Place the rodent and the paper towel into a sealed plastic bag. Place that bag into a second bag and seal again (double-bag method).
5. Disinfect the trap and reset, or discard the trap if disposable.
6. Spray and wipe the surrounding area again with disinfectant.
7. Discard the sealed bag in an outdoor trash receptacle with a tight-fitting lid.
8. Remove PPE following the doffing procedure (Section 4.2) and wash hands immediately.

Section 6: Sanitation & Decontamination Procedures

Trapping rodents eliminates the infestation, but the health risk does not end there. Rodent droppings, urine, nesting materials, and contaminated surfaces must be properly decontaminated. This phase is as important as the trapping phase and requires just as much care with PPE.

5.1 Approved Disinfectants

Not all cleaning products are effective against rodent-borne pathogens. Use only EPA-registered disinfectants with proven efficacy against hantavirus, Salmonella, and Leptospira.

5.2 Step-by-Step Decontamination Procedure

5.3 Attic Decontamination Special Considerations

Attic decontamination is significantly more complex than other areas of the home and often requires professional remediation. However, for smaller, localized attic contamination, the following additional guidelines apply:

• Contaminated insulation MUST be removed — it cannot be effectively decontaminated in place. Bagged rodent-soiled insulation is considered potentially biohazardous waste.
• Wear P100 full-face respirator, full Tyvek suit, double gloves, and boot covers — no exceptions for attic work.
• Bag insulation in heavy-duty contractor garbage bags (6 mil minimum thickness). Seal tightly and label as "Rodent-Contaminated Material."
• After insulation removal, spray all wood surfaces (rafters, sheathing, joists) with bleach solution and allow to dry before installing new insulation.
• New insulation should be blown-in cellulose (which contains borate, a natural rodent deterrent) or new fiberglass batts.
• If HVAC ducts pass through the attic, have them professionally inspected and cleaned — contaminated air circulated through your home's ductwork poses a direct inhalation risk to all occupants.

Section 7: Exclusion — Sealing Entry Points

Exclusion is the single most effective long-term rodent control strategy. Trapping and cleaning address an existing infestation; exclusion prevents the next one. A mouse can fit through a gap the size of a dime. A rat needs only a gap the size of a quarter.

6.1 Common Entry Points

• Gaps around pipes, conduit, and wiring where they enter through walls or the foundation
• Gaps where the roof edge meets the fascia board (roof rats are excellent climbers)
• Soffit vents without intact, fine-mesh screening
• Gaps around HVAC lines entering the home
• Foundation cracks and gaps, especially near the soil level
• Around garage door edges (worn weatherstripping)
• Dryer vents and bathroom exhaust vents without proper flap closures
• Any gap larger than 1/4 inch (mice) or 1/2 inch (rats) in the building envelope

6.2 Sealing Materials

Section 8: Long-Term Prevention Practices

The best pest control is making your home an unattractive target. Integrate these practices into your regular home maintenance routine:

7.1 Food Storage & Sanitation

• Store all dry foods (grains, cereals, pet food, birdseed) in rigid, airtight containers made of glass, metal, or heavy-duty plastic. Cardboard boxes offer no protection.
• Clean up all food debris and spills immediately. Mice can survive on 3-5 grams of food per day; crumbs are a buffet.
• Do not leave pet food out overnight. Schedule feedings and store pet food in sealed metal containers.
• Take out the garbage daily and use trash cans with tight-fitting, lockable lids.
• Compost bins should be sealed, rodent-resistant designs. Never compost meat, fish, or dairy products.
• Clean behind and under appliances (refrigerators, stoves, dishwashers) regularly.

7.2 Exterior Environment

• Keep firewood stacked at least 18 inches off the ground and 12 inches away from your home's exterior.
• Eliminate dense vegetation, leaf piles, and debris within 18 inches of the foundation; these are prime harborage areas.
• Trim tree branches so they do not overhang or touch the roof (roof rat highway).
• Eliminate standing water sources.
• Bird feeders attract rodents. If you use them, place them on pole-mounted baffles and clean up seed spills daily.
• Consider motion-activated lights in areas around the foundation to reduce the darkness that rodents prefer.

7.3 Ongoing Monitoring

• Conduct a monthly walk-through inspection of attic, basement, garage, and crawl spaces for signs of rodent activity.
• Check all exclusion seals seasonally — expanding and contracting temperatures can reopen gaps.
• Keep 1-2 unset snap traps in key locations year-round as monitoring stations. If you catch something, you know activity has resumed.
• Schedule a professional inspection with HAWX Pest Control annually. Prevention is far less expensive than remediation.
