The first step to pest control is knowing your pests, we can not walk around killing everything that moves. Moreover these pests have their fair share in the environment so killing is not always an option.
Step 1: The Good, the Bad, the Ugly
Even though bugs can be irritating there are some good ones, And some bad (in our view point ), and there is the ugly one (for somebody else they are beautiful )
Step 2: Mosquito
These are the most common pests you could imagine. They make this annoying noise and bite like hell. The bite area may turn to swelling while it bites it's saliva may get mixed with our blood. As a vector of diseases they are extremely deadly. Mosquitoes carry malaria, yellow fever, west Nile virus, Chikungunya, Dengue fever, Filariasis, zika and many more. Mosquitoes are a major disease carrier the for undeveloped countries (also for developed ones).
There are many mosquito traps and ways to avoid mosquito bites but most traps include electrocution which gives odors, Ultrasonic mosquito repellent not an option for people with pets( Especially dogs) and there are the repellent creams. The best method is to stop them from reproducing mosquitoes lay eggs on fresh and calm water and the larva grows in water. The water bodies are usually old cans, rooftop drainage, pots etc once we clean these places there is no more mosquitoes (Technically everyone have to get rid of them)
Step 3: Cockroach

They can even live days with there head cut off, Yup these are badass pests. They can survive a nuclear blast.

Which is harmful for cockroaches is also harmful for us also.Some traps are also there. Best way is to stop them from spreading clean your place once every month at least the kitchen. Arrange stuff properly so that cockroaches do not find shelter under them.
Step 4: Rats
Rats like to live where food is available easily and places they can hide in. Some grow to the size of an average cat. Since rats have very short gestation period (1 month) they grow in number very fast.
Using poison bites is the easiest method you just leave these where rats are usually seen. But for people with small kids and other pets it may be a little difficult because kids and pets may eat these baits, for such people mechanical traps without claws are preferred
