4. Name two methods by which pest and micro
ganisms can be Eliminated
Answers
Answer:
Pathogens are micro-organisms that can cause disease (infection) and are potentially harmful to humans. To cause disease, these pathogenic micro-organisms must first be passed on (transmitted) to a person and then overcome the body’s defence systems.
Clean the home regularly
Sweeping, mopping, vacuum cleaning, all these are essential in order to keep the home clean and tidy. Food particles sprinkled here and there attract pests and rodents. So cleaning the home regularly will not attract the pests. The pests feel comfortable in dirty and unhygienic environments, so if the home is clean, then the pests will not be tempted to dwell in your home.
Wash well
The clothes, bed sheets, bed covers, cushion covers, mattresses, rugs, carpets, all these things must be washed well, and you can use lukewarm water and the soap for this purpose. The bed bugs and the fleas often find their habitats in your clothes, so you must keep these clean. You can also beat the carpets and the rugs under the sun, with a stick, following the age old traditional method.
Keep the foods covered
Do not keep the foods open, as the smell attracts the insects like ants and cockroaches. The roaches carry harmful diseases with them, so they are highly capable of polluting your foods. If you find any soft mushy fruits or vegetables, or some food items on the verge of rotting, then you must throw them immediately in the garbage. Seal all the jars and the containers where you have kept the foods.
Wash the utensils
After the dinner is over, you store the unwashed utensils in the sink to be washed in the next day. The unwashed utensils like plates and the dishes with food crumbs on them stay in the sink the whole night. The night is a party time for the roaches, they find the strong smell of the foods and there is also darkness around. So, party times, they jolly well enjoy the food crumbs on your dishes, thus infesting them.
