Control of the House-Mosquito Group 



The formula for the control of this group — find all the water in 

 which it breeds, and make it unfit for breeding by di^aining, filling, 

 stocking with fish or the application of oil or larvicide — is as beauti- 

 fully simple as the practical work is difficult.

marsh mosquitoes bred here very intensively and migrated a distance of 



at least 2.5 miles. (Photo by Essex County Mosquito 



Extermination Commission). 



Satisfactory control of this group involves: (i) determination of 

 the size of the area which must be covered; (2) location of all 

 permanent breeding places; (3) provision for periodic inspection of 

 the territory (4) provision for treatment of all breeding-water sur- 

 faces. 



Determining the size of the area 



The size of the area depends upon the relation of the group to be 

 protected to large breeding places from which flights of mosquitoes 

 may come.
