Places in Nigeria that require cleaning service

The truth of life is that only those places in Nigeria and other countries can be clean where people are not throwing garbage in the streets, cars don’t pollute the air, and local services remove all the dirt and trash in time.

While every year the whole planet celebrates the World’s Environment Day on June 5, many people forget that the unclean environment around them is the main consequence of their own lifestyle.

Top ten most dirtiest states in Nigeria

Nigeria consists of 36 states plus the Federal Capital Territory. Most, if not all of these places in the country cannot boast being clean and free from litter. No government program can make the state officials and responsible services provide more waste bins across the area and teach locals how to take care of their environment and why it is so important for their own future.

This place in Nigeria is also highly polluted and littered. If you visit some of the local towns, for example, Nnewi, Onitsha or Nkpor, you will be shocked at once.

Just walk around and look by your sides. You will probably think that local citizens are extremely lazy because they cannot carry a single candy wrap in their pocket until finding a trash bin. All used wrappers, packages, and plastic bottles seem to end up right under the person’s feet as he or she strolls along the streets of Anambra State.

Besides, based on information, Onitsha became the world’s most air-polluted city in 2016. Its PM10 levels exceeded the World Health Organization’s recommendations by 30 times.

This place is one of the most populated in Nigeria. It is well developed compared to smaller areas. It is called the economic center of the country, but it is also the dirtiest state in Nigeria.

How is it possible? Maybe it is the local culture, or perhaps it is the lack of education towards the importance of environment protection. The reality is sad, but many car drivers and passersby can easily throw their litter right on the roadside. If you walk the streets, you will be surprised at how much garbage is under your feet.

4. Kano State

Being highly populated or economically wealthy doesn’t guarantee that state or city will be clean, nice, and comfortable to live in.

Kano residents also suffer from waste, garbage in the streets and dirt. While this place is loved by tourists and surrounding villages are welcoming and friendly, the sanitation here is poor, and this is one of the main reasons why the state is added to our list.

These territories are quickly developing economically, but the state suffers from litter, dirt, and air pollution. Too much fumes and vehicular emissions in the air can lead to chronic asthma and different health issues, while the garbage in the streets make the cities of this Nigerian state look depressive and unappealing to tourists.

The capital of the state, Kaduna, looks way cleaner than the rest of the region where locals don’t seem to care too much about cleaning the streets and suburbs from trash. But still, this city was featured in the report by World Health Organization in 2016 as one of the most polluted areas in the world with a lot of smog, water pollution, and rubbish, according to

6. Osun State

7. Ogun State

While this Nigerian territory is not as dirty as Kaduna or Abia States, people who live in Ogun lack a good waste management system.

The garbage and dirt have to be disposed of in the correct way, which doesn’t happen here right now. This can change soon, as according to, the state has found a private company that can manage its municipal waste and help clean the territory from the litter. The company should provide the full-waste cycle, as it will collect, process and dispose of all the wastes.

9. Benue State

Unfortunately, this dirtiest state in Nigeria cannot boast great environmental conditions. Even the capital of the state, Makurdi, does not look nice and clean.

Everything can be explained by the local culture.

Besides, the capital, as well as smaller towns, lack portable drinking water even though there is the famous Benue River here.

While it can be complicated to name number 1 dirtiest state in Nigeria, we can say that people who live in Lagos, Anambra, Abia, Kaduna, Oyo, Benue, and other of the ten states we listed should think about their future and the future of their children.
