electronic deer repellents

Asked June 6, 2017, 8:11 PM EDT

Are any of the electron deer repellents, like those described on the following site, effective? I live in Baltimore and I want to protect freshly planted acuba, pachysandra, and the like. Thanks. ,,, wdc http://www.target.com/p/ultrasonic-deer-repeller/-/A-10884757?ref=tgt_adv_XS000000&AFID=google_pla_df&CPNG=PLA_Patio+Garden+Shopping&adgroup=SC_Patio+Garden_Top%20Performers&LID=700000001170770pgs&network=g&device=c&location=9007767&gclid=CjwKEAjwpdnJBRC4hcTFtc6fwEkSJABwupNiuY9WA_rCJbvMyLV8wfkzTWUmL1TYrLTgz7GlZ4bn9xoClWHw_wcB&gclsrc=aw.ds

We have no research that these electronic products work and do not recommend them. There are several spray deer repellents on the market that are very effective.

It's a good idea to be aware of how attractive each plant is to deer before you plant. Once planted, deer may nibble on some shrubs when the shrubs are young and tender and then leave them alone as they get mature. Other plants are deer candy.
Keep in mind that if there is intense deer pressure (high deer populations and little to eat), that deer will ultimately eat anything to survive.

That said, please look over our two fact sheets with listings of plants and their susceptibility to deer: http://extension.umd.edu/sites/extension.umd.edu/files/_images/programs/hgic/Publications/non_HGIC_F...
