Mosquito nets offer critical protection against a terrible disease. Some estimates suggest Mosquitoes might be responsible for the deaths of as many as half of all human beings who have ever lived. Mosquitoes feed on the blood of humans. As they move from host to host, they can take blood born diseases with them. The elephantiasis-causing filariasis worm, yellow fever, various forms of encephalities and malaria can be transmitted by mosquitoes. According to the Centers for Disease Control, mosquitoes kill 2 million each year. Children are particularly vulnerable, due to their weaker immune systems.

Bell nets are probably the most recognisable form of mosqutio nets. Suspended from a ring, they fan out to cover your bed. Those mosuqito nets which require hanging (be it from a hook, wall or clothes lines) come with the necessary kit.

Freestanding nets pop up like tents and can be used by those out camping or who don't have somewhere from which they can hang a traditional net.

Of course, if you are off travelling then you may not always know where it is you are going to be staying. Compact mosquito nets are the answer. They are small enough to be carried in backpacks or hand luggage; the perfect choice for those off travelling the globe or trekking around Thailand.

While a net is essential, the World Health Organisation (WHO) recommends that anyone travelling in a malarial zone should take the extra precaution of having their impregnated with an insect repellent with a minimum strength of at least 50% DEET. Long Lasting Impregnation (LLI) kills mosquitoes as soon as they land on the net. "Long Lasting" means 2 years; after that you will need to reimpregnate the net, but this is easily done. Reimpregnation is a simple process that can be carried out at home. Draw the net through a solution of the anti-mosquito treatment and leave to dry.

Mosquitoes bites are most likely to occure during the night, as this is when the insects are at their most active. If you are planning activities during the early morning or evening, it's still important to keep yourself protected by mosquitoes. You may be up and moving, but that won't stop them trying to bite. Head nets are made of a fine mesh that offers you clear vision while also keeping the mosquitoes off your face.

Of course, mosquitoes can be a pest even if they are not carrying dangerous diseases. For that reason, some mosquito nets are available in non LLI versions which are suitable for using in the UK and other non malarial areas.

If you are travelling in sub-Saharan Africa, Asia or the Americas, it is important you take a mosquito net along. Whether you're staying in a double bed in one hotel or trekking through the mountains, sleeping beneath the stars every night, there is a net suitable for your requirements. Malaria is a dreadful problem, but there are basic steps you can take to avoid the worst of it.
