How to Control Insects in Your Community
Have you been wondering how people control insects that can cause vector borne diseases like malaria in their communities?
Some of us have been getting the notion that diseases caused by insects are worldwide! Not actually.
Winter experiencing countries like Switzerland hardly report vectorborne diseases. In fact, there are no mosquitoes in Iceland according to study reports!
So, vector borne diseases vary in prevalence from one region to another.
In determining potential incidence of these diseases, you must therefore identify and determine the prevalence of vectors that act as primary transmitters.
Effectively, you can control vectorborne diseases through the combination of the use of vaccines or chemotherapy.
Types of Insects of Environmental Health Significance.
In essence, they include flies, fleas, lice, mites, mosquitoes, cockroaches and ticks.
Basically, it is very important to understand biological characteristics, breeding, habits and mechanism of spread of the diseases (spread) by each insect.
In the long run, this will assist you in instituting adequate chemical, physical and biological and mechanical controls.
Inspection and Surveys
i.) Fly Surveys
This method is used to determine those areas in which flies are in greatest concentration. It is also used to determine kind of flies in order to use effective controls. More so, to determine the potential spread of the disease.
There are several types of fly surveys in the community:
- Fly Traps – They consist of fly papers or cones. These fly traps can capture a cross-section of flies in a given area.
In addition, they can classify them according to species. You can line them with animal stools, sugar, fish or any other decaying matter to attract the insect.
- Fly Grills – It is the most used. They use natural attractions like gabbage, manure or any decaying matter. It kills the fly very fast.
ii.) Mosquito Surveys
Strategically, these are necessary for planning your operation and evaluating your mosquito control programmes.
Actually, we use the basic survey to determine:
- The species of the mosquitoes.
- Breeding places.
- Flight distance.
- Larval habits.
- Information actual control.
How do we control?
We can control mosquito larvae mechanically, biologically or chemically.
So, mechanical control involves emptying and removing all temporary containers such as cans, old tyres e.t.c
Chemically, using oil and other chemicals. Biological technique of eliminating the larvae is to stock the lakes and the rivers with golden fish.
When performing space spraying for adult mosquitoes, you have to accompany it by use of aerosols, fogging and dusting.
Most importantly, take note that the prevalence of malaria is very high.
Before DDT was used for mosquito control, the principal technique used to eliminate larvae was through the use of chemical larvicides.
iii.) Fly Control
They include mechanical, physical and biological control.
In order for you to eliminate flies successfully, you have to properly dispose solid waste.
Get in mind that animal feeds and stool are the best breeding sites for flies.
Finally, it is important to note that the insects become resistant to insecticides and for this reason, majority of them are out of use.
