Mosquito Dunks Work Within 24-48 Hours

Mosquito Dunks begin killing mosquito larvae within 24 hours of application. The active ingredient Bacillus thuringiensis israelensis (Bti) targets only mosquito larvae, making it safe for people, pets, and wildlife.

How Mosquito Dunks Work

  • Bti bacteria produce toxins that affect mosquito larvae digestive systems
  • Toxins are harmless to humans, fish, and beneficial insects
  • Effectiveness depends on water temperature and mosquito species

Application Process Timeline

  1. Apply Dunks to standing water sources
  2. Initial larval death occurs within 24 hours
  3. Complete control typically takes 48-72 hours
  4. Reapplication needed every 30 days for ongoing protection

Comparison of Mosquito Control Methods

Method Time to Work Cost per Treatment Duration of Effect
Mosquito Dunks 24-48 hours $15-25 30 days
Larvicide Sprays Immediate $20-35 7-14 days
Biological Controls 48-72 hours $30-50 60 days

Factors Affecting Effectiveness

  • Water temperature above 50°F speeds action
  • Still water allows better distribution
  • Proper dosage ensures complete coverage
