  4. Treatments for standing water • Bacillus thuringiensis (briquettes and granules) • Methoprene (Altosid, Pre-Strike) granules

  5. Backyard foggers • Thermal foggers • Aerosol foggers • Temporary relief from mosquitoes • Few hours to few days

  6. Residual insecticides for mosquito control • Treat mosquito resting sites • under eaves of buildings • around doorways • trees • shrubbery • foundation plantings • 3-4 weeks residual control PCT magazine Oct, 2006 for University of KY studies

  10. Drawbacks • Non-selective, may kill beneficial insects

  11. Treat outside and around doorways • Use residual insecticides • Lambda-cyholothrin • Deltamethrin • Bifenthrin • Cyfluthrin • Little risk to beneficials

  12. Mosquito misting systems • More expensive than spray services • Effectiveness and impact on beneficial insects not well studied • Probability of pesticide exposure and over-application by homeowners • Effects on mosquito resistance not well studied

  13. Bug zappers & other “sure-fire” mosquito remedies • Zappers ineffective in reducing mosquito bites • Citronella plants not known to repel mosquitoes • Citronella candles, torches can repel mosquitoes if wind is favorable
