no it's not.
mosquitoes are a huge issue here. we live near the river, have big manure piles and a pond and a 700 acre cow farm across the lane. we breed hellacious bugs.
there are plants you can put in that are natural deterrents, although they are by no means close to 100% effective. but if you combine a lot of natural solutions (don't allow standing water, use Bt or diatomaceous earth in boggy places, plant lots of basil and lemongrass and chrysanthemums, put in bat houses) you can still enjoy being outside by adding physical barriers like netting over hats, light long-sleeved clothing and natural bug repellent.
i do use DEET but very sparingly, only when i'm going hiking or camping or otherwise venturing into the woods.
