How to Eliminate Bed Bugs

Integrated pest management (IPM) combining both non-chemical methods and targeted insecticide use is the most effective approach for eliminating bed bug infestations. 1

Identification and Assessment

• Look for these signs of bed bug infestation:
  • Clusters of small, red, itchy bites in a linear or curvilinear pattern on exposed skin
  • Small red punctum at the center of bite marks
  • Three bites in a row (classic "breakfast, lunch, and dinner" pattern)
  • Rusty or reddish stains on bed sheets (from crushed bugs)
  • Dark spots (bed bug excrement) on mattresses, bedding, or walls
  • Shed skins, eggshells, or live bed bugs in mattress seams, furniture joints, and cracks

Effective Elimination Strategy

Step 1: Non-Chemical Control Methods

1. Thorough Cleaning:

   • Remove clutter to eliminate hiding places
   • Vacuum all surfaces thoroughly, especially mattress seams, box springs, bed frames, and nearby furniture
   • Immediately seal and dispose of vacuum bags outside the home

2. Heat Treatment:

   • Wash all bedding, clothing, and washable items at 60°C (140°F) 2
   • Tumble dry on hot cycle (>40°C/104°F) for at least 30 minutes 2
   • For delicate items that cannot be washed in hot water:
     • Dry cleaning with perchloroethylene
     • Freezing at -17°C (1.4°F) for at least 2 hours (note: loosely packed laundry takes approximately 8 hours to reach this temperature) 2

3. Isolation and Barriers:

   • Install bed bug interceptors/traps under bed and furniture legs
   • Encase mattresses and box springs in specialized bed bug-proof covers
   • Move beds away from walls and ensure bedding doesn't touch the floor

Step 2: Chemical Control Methods (When Necessary)

• Caution: Improper insecticide use can lead to health risks. One study identified 111 illnesses associated with bed bug-related insecticide use, including one fatality 3

• Effective Products:

  • EcoRaider (1% geraniol, 1% cedar extract, 2% sodium lauryl sulfate) - shown to cause >90% mortality in nymphs and 87% egg mortality 4
  • Bed Bug Patrol (0.003% clove oil, 1% peppermint oil, 1.3% sodium lauryl sulfate) - also showed >90% mortality in nymphs 4
  • Synthetic pyrethroids (if used by professionals)

• Application Guidelines:

  • Apply insecticides only to cracks, crevices, and other hiding places
  • Never apply directly to mattresses or bedding unless the product label specifically allows it
  • Follow all label directions precisely
  • Consider professional application for severe infestations

Prevention of Reinfestation

1. Regular Monitoring:

   • Inspect bedding weekly for signs of bed bugs
   • Use monitoring devices (passive sticky traps or active CO₂ traps)

2. Environmental Control:

   • Maintain indoor humidity between 35-50% 5
   • Seal cracks and crevices in walls, floors, and furniture
   • Reduce clutter that provides hiding places

3. When Traveling:

   • Inspect hotel rooms before unpacking
   • Keep luggage elevated and away from beds and walls
   • Wash and dry all clothing on hot cycles upon returning home

Important Considerations

• Treatment Duration: Complete elimination often requires multiple treatments over 2-3 months
• Whole-Building Approach: In multi-unit buildings, adjacent units should be inspected and treated if necessary
• Resident Cooperation: Success rates are significantly higher with full resident cooperation 6
• Professional Help: Consider professional exterminators for severe infestations

Treatment Efficacy

Research comparing three bed bug management strategies found that after 10 weeks 6:

• Non-chemical methods alone eliminated bed bugs in 67% of apartments
• Insecticides alone eliminated bed bugs in 33% of apartments
• Integrated pest management eliminated bed bugs in 44% of apartments

This suggests that thorough application of non-chemical methods can be highly effective, especially for light infestations, but an integrated approach may be necessary for more severe cases.
