Mosquito nets have been around since 6th Century B.C. There is a lot of talk about treated mosquito nets at the moment so we thought it advisable to write about the facts of these essential items – especially when travelling to disease prone areas, which now includes part of Europe, thanks to Climate Change.
There are 2 main varieties of mosquito netting, impregnated and non-impregnated. The latter are great when there is no disease around and it does not matter if you get the odd mosquito bite during the night, they can be manufactured in natural fabrics such as cotton, or synthetic materials...which reminds us of yet another reason not to use Deet; if it comes into contact with your synthetic net the chances are that it will dissolve parts of it!
The other variety is impregnated, which is treated with a chemical, and a good one will kill any mosquito or other insect that lingers too long on the outside of the net. Think of a mosquito pushing her proboscis through one of the holes, trying to locate your skin. Quite a few insecticides will do this and they are all very safe if they come into contact with humans. However, there is a reasonable risk when re-impregnating a net –the majority of nets available in UK stores need this treatment every 6 months- this is also not good for the environment. Therefore, a longer-lasting impregnation (LLI), like Durallin (DAWA) is much preferred as they last for 3 years and every time a DAWA net is washed it is as good as new.
Nylon and polyester nets being light and flexible can be wrung well after dipping, with little emulsion wasted from dripping while drying. With cotton, the insecticide solution drips even after thorough wringing leading to some waste of insecticide. Polyethylene and polypropylene nets with thick and rather stiff fibres are difficult to wring.
In general, multi-filament synthetic materials (polyester, nylon) are preferred because:
- they are generally cheaper than cotton materials; although cheap cotton nets are also made e.g.in China and India;
- they are easier to impregnate;
- they absorb less insecticide;
- a given dose of pyrethroids is more effective on them, and less insecticide is lost during washing and drying;
- they are more durable;
- they allow more aeration to the net users.
The insecticide is a strong poison when in liquid form and can cause problems especially in under-developed countries because of poor sanitation.
However much you dislike using toxic chemicals if you want to avoid malaria and other potentially fatal illnesses it is imperative that you sleep under an impregnated mosquito net. NB no topical insect repellent can protect you throughout the night, whatever it says on the label!
The best mosquito net will keep out all insects, but these are few and far between. The WHO recommends 156 holes per square inch (hpsi) as standard, which will restrict nearly all adult female mosquitoes (Males do not suck blood and have no capability to do so), though that will still leave many biting insects that can squeeze through- it is only when you use a net that has 350 hpsi that you stop most insects from sharing your bed. There is a downside with very many-hpsi nets i.e. 400-500 and more, in that in humid climates the airflow can be heavily restricted and not even an overhead fan will blow the stuffy discomfort away.
In summary, only buy a good quality, sturdy, impregnated (If you are going to be exposed to risk) mosquito net that has an hpsi of no more than 400. It is worth paying the extra money for a LLI net as this will work out more cost-effective over time and be kinder to our planet.

Keep insects and other vermin at a distance and ensure a peaceful nights rest. Mosquito nets only provide extra protection against mosquitoes and malaria mosquitoes when they are closed on all sides, are made of durable polyester and their mesh is no courser than 1.75 mm. If the mesh is too fine, it can become muggy under the net in a damp tropical or subtropical climate and so is not suitable for those purposes. Our Mosquito Nets were designed in an atelier in Holland and are manufactured under the strictest quality standards. The high-quality multi-fibre polyester is ideal for durable impregnation and guarantees a long life span. For optimum protection it is essential to impregnate the mosquito net with the proper concentration of contact insecticide. The contact insecticide used on all our impregnated Mosquito Nets is deadly for mosquitoes and other vermin, but harmless to people. Impregnation provides extra protection as mosquitoes do not even get the chance to land on and bite through the net. The WHO recommends Long Lasting impregnated mosquito nets for high-risk malaria areas (tropical Africa, Amazon region, parts of South East Asia).
Mosquito nets are available in 2 varieties: untreated and Long Lasting Impregnation (LLI). If using the latter with incognito® spray then it is clinically proven to protect against malaria.
Untreated mosquito nets are ideal for at home or where there is no mosquito-bourne diseases. When travelling to areas where malaria or other insect-bourne diseases are a risk factor, impregnated mosquito nets are recommended. Standard impregnated mosquito nets remain effective for only 6 months when used.
The nets are washable but no longer effective once washed. After being washed just once they must be impregnated again, which not only puts a strain on the environment but costs you more financially. The useful lifespan of the impregnation improves if impregnated mosquito nets are stored in a dark space after use.
We only stock Long Lasting Impregnated(LLI) mosquito nets which you rarely get on the High Street. incognito® is the first company to introduce them into the UK. By using this new technology the impregnation remains effective 5 times longer than standard impregnated mosquito nets. Furthermore, the nets can be washed without losing their effectiveness. All LLI mosquito nets sold by us meet the requirements of the WHO (World Health Organization). The impregnation is effective up to 2.5 years when used daily and the treated mosquito nets can be washed up to 20 times.
The mesh we use in our nets has 365 holes to the inch, which is over twice the recommended standard for effective malaria protection of 156. The small sand fly, however, which also transmits diseases to humans, can pass through the mesh size on the majority of nets but not with our bed mosquito nets, due to their smaller holes/finer mesh. Indeed, all of our nets will keep out all insects. Peace of mind while you sleep!
These nets can withstand at least 20 washes without losing any efficacy. Store the net in its handy case for maximum effectiveness when not in use. We give 10% of profits to charity.
All our mosquito netting is durable and lightweight.
You can always use a larger mosquito net on a smaller bed.
Use insect repellents safely. Always read the label and product information before use.
