Status of Mosquito Control in New Jersey

 QUITO EXTERMINATION COMMISSION 



INTRODUCTION 



Last year we were able to say ''approximately 95,000 acres of 

 the salt marsh have been rendered reasonably free from mos- 

 quito breeding. This has involved the cutting of 11,500,000 

 linear feet of ditches 10 inches wide and 30 inches deep, or their 

 equivalent, the building of 17.2 miles of dike, the installation of 

 76 sluice and tide-gates (representing 842 square feet of cross 

 section), and the installation of one 4- and one 12-inch cen- 

 trifugal pump. Approximately 50 per cent of the reasonably 

 permanent pools scattered over 315,000 acres of upland, has been 

 permanently eliminated. * * >k Approximately 95,000 acres 

 of salt marsh have been patrolled throughout the mosquito 

 season, and the mosquito breeding destroyed in so far as possible. 

 Approximately 315,000 acres of upland have been likewise pa- 

 trolled, a large amount of drainage and filling completed, and, as 

 nearly as possible, all residual breeding destroyed. 



"Not a single brood of any consequence has emerged during 

 the past season from the 95,000 acres which have been drained." 



This year we can say that 9,000 acres of drained marsh can be 

 added to the 95,000, making 104,000 acres, and that all of this 

 area has been patrolled throughout the mosquito-breeding season, 

 and that, in so far as practicable, all residual breeding has been 

 destroyed. We can say that, as last year, 315,000 acres of up- 

 land have been patrolled, many breeding places permanently 

 eliminated, and, in so far as practicable, all breeding has been 

 destroyed. We can say that while mosquitoes were at times 

 troublesome in the protected area, in comparison with conditions 

 in unprotected areas the protection afforded was very real indeed.
