Influence of landscape factors on density of suburban white-tailed deer March 27, 2013 RE Urbanek, CK Nielsen - Landscape and Urban Planning, 2013
... We assessed the influence of landscape factors on density of suburban deer on 40 forest preserves in northeastern Illinois during 1999–2002 ... Patch density of agricultural land within preserve borders (ω = 0.95; β′ = 0.47), the mean nearest neighbor distance between all cover patches within preserve borders (ω = 0.95; β′ = 0.38), the diversity of patch types within preserve borders (ω = 0.66; β′ = −0.24), and the percent core area of forested land within preserve borders (ω = 0.52; β′ = 0.21) were the strongest predictors of suburban deer density. Natural resource managers should limit agricultural practices, reduce core areas of forest patches, and increase diversity of land cover patches within preserve borders to potentially reduce deer densities and limit deer population growth...
Field-edge planting to deter white-tailed deer and attract carabid beetles in soybean fields A Mullins - 2014 Nova Scotia, Dalhousie University
... This study tested whether or not damage to soybean from white-tailed deer could be reduced by field-edge plantings, while increasing the abundance of predatory ground beetles in the same soybean fields and subsequently reducing numbers of soybean aphid, Aphis glycines, on soybean plants... The two treatments in 2013 were: alfalfa + red clover + orchard grass and soybean (control). Deer grazing damage to soybeans was significantly lower in areas adjacent to a legume + orchard grass field edge planting....
Deer repellents, such as liquid scents, perfumes, and even human hair, may work well for a period of time, but deer may become accustomed to these scents over time. Change scents weekly to maintain these repellents’ effectiveness. Direct spraying of plants with capsaicin, the chemical that makes peppers “hot”, works well, but must be performed frequently, -- rain and dew will wash it away. Soak ground hot pepper in water overnight then spray on the plants.

Electrode design for deer repellent device January, 2013 KM Betzen - US Patent 20,130,008,390, 2013
An improved electrode design is provided for a baited, shock-producing, deer repellent device deployed in an area to be protected. This device has straight, parallel, positive and negative, un-insulated metal electrodes extending vertically from the top. The electrodes are spaced and sized so that they surround and protect the bait. This electrode design increases the chance that a deer will make effective contact with the electrodes while also allowing easy access to the bait for servicing. This electrode design also decreases the chances of the device collecting ice or snow, and it decreases the chance of discharge of the device by moisture or by contact between the electrodes.
