(A) Mosquito Larve
Assessment
Problem is seen in the open area and may also be seen in other areas
during the season. Mosquitoes need water and high levels of moisture to sustain them.
Although stagnant water is the prime location for them to reproduce, there are many
other locations around the premises. Such places include water in drainage streams,
sewers, swimming pools, decorative ponds or any water accumulating. Mosquitoes
need water to reproduce and they readily move to moist shady areas in dense shrubbery, which may be watered during the hot summer, months. It is necessary to
determine prime nesting and sheltering locations of mosquitoes before putting into
place any prevention program.
(B) Adult Mosquito
Assessment
Usually Fogging treatment to be carried out mainly to control Adult mosquito ( dengue) and flying Insects. This treatment gives a lot of relief by destroying adult mosquitoes. Treatment will be providing inside the building and outside the building by Fumigation machine.
(a) Mode of Treatment:
The basic sampling unit is the house or premise, which is systematically searched for water holding containers. Containers are examined for the presence of mosquito larvae and pupae. Depending on the objective of the survey, the search may be terminated as soon as Aedes larvae are found, or it may be continued until all containers have been examined.
Method of Application will be as follows-
1. CHEMICAL CONTROL whereby chemical insecticides are used to kill the mosquitoes, such as by fogging. Chemical insecticides can also be applied directly to mosquito breeding sites or resting sites (indoor and outdoor spray) to kill the larvae and adults respectively;
2. SOURCE REDUCTION by removing containers, tyres etc. in which water can collect and mosquitoes can lay their eggs;
3. ENVIRONMENTAL CONTROL to eliminate the breeding by altering the environment to make it unfavourable for mosquitoes to breed. One noted example is sub-soil drainage, where drains are buried to make them inaccessible to mosquitoes;
(b) Frequency:
Mention the frequency depending on the type of premises/level of infestation.
(c) Pest Management log sheets:
As required will be maintained with details of the chemicals used and areas with date & time of treatment and client signature etc. Inspection card/Progress report (IC/PC) will be generally used in most of the cases. However specially designed log sheets will also be used in some cases depending on the type of client.
(d) Suggestions to clients on Preventive Measures to be taken:
For this treatment to be effective, an integrated approach- involving you (/ your production / maintenance staff is necessary.)
Empty water from buckets, tarps, cemetery urns, water troughs, or other containers.
Get rid of old tires.
Change water every other day in birdbaths, fountains, rain barrels, and potted plant trays.
Drain or fill puddles and low spots with dirt or landscape to reduce standing water.
Treat and clean swimming pools and keep them circulating.
Wear long sleeves and long pants if you must be in areas with lots of mosquitoes.
Make sure windows and door screens are "bug tight."
Drill holes in the bottom of containers that must be left outdoors, such as garbage cans.
Check your roof gutters and adjust to eliminate standing water.
Methodolgy with Spray:
The use of larvicides which are generally applied to stagnant water where mosquitoes breed.Providing & Applying chemicals for Anti-larva operation at all stagnant water pools, ponds, nallahs and open areas which are identified as source for mosquitoes breeding in the inner township and up to 1.0 kilometer outside the township boundary wall.
Methodolgy with Fogging (Cool & Thermal):
Chemical to be diluted with diesel or kerosene and applied as thermal fog or
ultra low volume aerosol spray @ 1 part of chemicals dilute in 199 part of diesel of kerosene to cover 20 hectare. More frequent applications may be necessary where there is a
continuing insect challenge. For mosquito control the spraying should coincide with the peak activitiesbiting times of the species, for most species this is at night.
Treatment outdoors should not take place during the heat of the day or if it is raining.
