The animals that vectors weaken livestock or transmit disease are capable of carrying a disease organism to the animals. or parasite from one host to another are called vectors. Public health pest Successful control of a vector pest involves management programs are usually directed several steps. The pest must first be against these vectors with the belief that correctly identified and its biology controlling the vectors will control the understood. Next, the pest infestation disease. The success of this approach is should be evaluated and finally, the evident by the eradication of malaria and selection of a control strategy may be yellow fever from many parts of the world implemented. If pest control is to be through control of the mosquito vectors. successful, it must be based on knowledge 1 and understanding of the pest’s biology, pest as spilled food or the presence of other items management technology, and environmental that attract pests. Once the pest is located, it safety concerns. must be positively identified to proceed The communities supporting a vector effectively. Many times identification must management program will be more be made from indirect clues such as damage cooperative if they understand the general or droppings. After the pest is identified it is methods and goals of the program. A easier to identify shelter areas and the means mosquito control program must reflect by which the pest gained entry. Some current legal conditions and community knowledge of the biology of the pest is very concerns. Community concerns should be useful for thorough diagnosis. Failure to reflected in vector control and public properly identify the pest can result in opinion should not be ignored. wasted time, money, pesticides, and labor. BASIC STRATEGIES PRESCRIPTION INSPECTION Prescription includes how, when, where, and what control techniques are needed to Inspection includes asking questions, control the pests. Effective prescriptions are inspecting the structure or structures, and determined only after inspection and inspecting other areas thoroughly to learn as diagnosis are completed. The prescription much as possible about the pest problem. should include the appropriate control During the inspection an applicator should strategy and any modifications to the look for locations where conditions favor existing habitat that will need to occur. infestations. Note the presence of food People should clearly understand that the and/or water that will attract pests and effectiveness of any control strategy is structural defects or openings that may serve reduced if problems such as sanitation, ease as a means of pest entry. Also, look for of entry, and re-infestation are not evidence of infestation such as structural addressed. damage and pest droppings or tracks. Successful pest control strategies commonly The inspection process should provide some include a pesticide application combined idea of the control measures to use, safety with other control measures such as habitat precautions that may be necessary during the adjustments. Habitat adjustments should control effort, and the best time and method include sanitation efforts to remove sources of control. Thoroughness during the of food, water, or other attractants that the inspection is a critical component of pest needs to survive.
