What about a mozzie zapper or it that the same as the one you were using. When we go to the farm we always have to take our mozzie zapper with us or we get eaten alive. The nights are usually when they are worse.

The one you were using can you reduce the time between sprays?

Are you near water or do you have water in pots etc near you. Water is the main breeding source for mozzies so if you can eliminate the source then that will help.
