White-tailed deer have poor daytime vision; and without one such deer fence accessory, whitetails may risk running into the system. Therefore, deer fence warning banners are recommended when installing deer fence. 

The warning banners are white flags that deer can easily spot to alert them of a structure in front of them since they have trouble seeing the black color of the fence mesh. White deer fence flags are easy to add and are affordable.

For placement, we recommend that you tie one white warning banner on the fence for every 10 feet at a height of 4 feet. Do not place the flags at the top of the fence to help deer gauge height for jumping attempts.
