While DEET can repel all mosquitoes, ticks, and some flies, DEET does not repel all flies effectively. For those situations you will need the extra protection Sawyer® DEET Plus Lotion which has the special fly repellent, R-326. This is added to the formula and is effective against flies, gnats and no-see-ums. For times when sprays are more convenient than lotions, this is the formula to use.
