Checking for Mosquito Breeding Areas in a Household

Environment and Health

POTENTIAL Mosquito breeding areas and ACTUAL mosquito breeding areas:
Mosquitoes breed (lay eggs) in accumulated water. Hence we need to look for areas where water accumulates for sufficient time period.
Some common places to check for water accumulation are as follows:
Inside the house

  • Desert coolers
  • Flower vase
  • Potted plants
  • Water tanks, cisterns, and other stored water
  • Old cans, tyres, coconut shells, bottles, paper cups lying in open, etc.

Around the house

  • Puddles and roadside ditches
  • Open drains
  • Cess pools
  • Soakage pits
  • Old non-functioning fountains, bird baths, ornamental pools, etc.

The water collections should be visually inspected for the presence of mosquito larvae and pupae. These can be seen in the figure below.

If mosquito larvae are spotted in the water, report as ‘Mosquito Breeding Site’. If no larvae are detected yet, report as ‘POTENTIAL’ mosquito breeding site.
