Tips for Reducing Mosquito Callbacks

Tips for Reducing Mosquito Callbacks

Learn how to maximize your time in the field with these tips for reducing mosquito callbacks. Callbacks and retreatments for your mosquito service can be costly, time-consuming, and usually result in unhappy customers or the service being cancelled. Here are a few tips to help you avoid them.

Top 14 Tips for Reducing Mosquito Callbacks

  1. The number one reason for callbacks, in my experience, is improper or a lack of inspections on each visit.
  2. Do the proper math on the treatment area and apply the correct amount of product.
  3. Use the highest label rate allowed for the first treatment of the season.
  4. Use the proper application technique to get maximum penetration and product on underside of vegetation and other resting places (under decks, sheds, etc.).
  5. Vegetation grows quickly in summer. Be sure to target NEW vegetation on each service.
  6. Rotate chemicals with different modes of action to avoid resistance.
  7. Many times the breeding sites are on adjacent properties. If you suspect this:
    • Offer a free inspection to the neighbors.
    • Incorporate traps in your service to intercept egg-laying females coming onto your customers’ property.
    • Ask your customer to speak with the neighbors about your service.
  8. Keep vegetation trimmed to impact CAPT Stan’s Big Four where mosquitoes hang out: shade, moisture, cool, out of wind.
  9. Set/manage customer expectations. We aren’t very good at this as an industry. If you advertise ‘eradication’ or ‘no more mosquitoes’, you will have callbacks. I prefer the phrase ‘nuisance reduction’.
  10. Recommend floor fans and use of repellents in between services (CDC has a great website on the latter - Insect Repellents Help Prevent Malaria and Other Diseases Spread by Mosquitoes (
  11. Verify with customers where in the yard they are being bitten and what time of day. This will provide clues as to what species you are dealing with.
  12. Check for cryptic breeding sites such as plant drainage saucers, piles of leaves, corrugated attachments for downspouts, clogged gutters, etc.
  13. Change outdoor lighting scheme to sodium vapor. Many species of mosquitoes are highly attracted to ‘regular’ light.
  14. If a problem persists, try and get the mosquitoes identified. This can be done by your Chief Science Officer (if you have one), technical specialist, a local mosquito abatement district, or an entomologist at a local university.
