I was reading the following blog https://ru-abandoned.livejournal.com/1501621.html and couldn't find a translation of the word "ягоза" that made sense from the context. According to the dictionary, "ягоза" is a "fidgety person". A quick search on google brings up a video clip entitled "ягоза- масленица"; and after watching this, it seems that this word can have also a somewhat more positive connotation, as in "can't stand still (from having so much fun)". The full sentence is "Свежий забор, ягоза и попискивающее дачло явно намекало на то, что незваным гостям там не рады". My translation is, "A new fence (COMMENT: I was also thinking that this could possibly mean 'live fence', as in being an 'electric fence') X and a beeping sensor clearly insinuates that uninvited guests are not welcome (here)"
