I’ve got a mosquito net I’d like to treat since I’m sure it’s lost all the chemical that was on it when I first purchased it two years ago. When I first started using it, it seemed to work better. Now I see mosquitoes and other small insects are landing on it and they don’t seem to be bothered at all by it. What can I spray on it to make it repel them?

The most common mosquito net treatment is to spray it with PERMETHRIN which you will find listed in our MOSQUITO CONTROL ARTICLE. Permethrin is odorless, won’t affect the netting in any way and will actively repel and/or kill any mosquitoes that land on it. As a general rule, you should retreat the net once a month if it’s left outside in the sun and not washed or stored.

If you store the net out of the elements and only take it out when in use, treatments should last longer and may not be required as frequently. If you wash the net with detergents, you will need to apply more Permethrin at least once every two washes if not more frequently. This is because the washing will effectively remove all of the Permethrin each time it’s washed.
