Insect repellent with DEET!
Agreed ! However,.. I understand that 20%- 30% DEET is effective
but needs to be applied to only clothing and lower extremities, hands and arms,
and may need to be re-applied after 2 - 6 hours.

There are also organic oils and herbals which will repel various insects,
but their efficacy is dependent on the percentage of oils and inert ingredients.
