I'm not really into the chemicals, especially for residential and rural areas. There are numerous alternative/natural products available that really work well. For a start, you may try here:

For example, I use a non-poisonous mint-oil based spray around the home for wasp. It shoots up to 20+ feet and takes em' out without any problems, and more importantly, no toxic chemicals that are going to linger or drain in to the surrounding areas.

It leaves a "fresh minty" aroma afterwards
