Zvinotora anenge 4 mavhiki kutian ultrasonic repeller kuti abudirire kudzinga zvipembenene.
Mumavhiki ekutanga kusvika maviri, vashandisi vanogona kuona kuti zvipembenene zvakanyanya kushanda pane kusashandisa zvishandiso.Izvi zvinodaro nekuti mafungu e ultrasonic uye emagetsi anoburitswa nemichina anotanga kurwisa tupukanana 'auditory system, sensory nerves, central nervous system, uye reproductive system, zvichiita kuti vasanyanya kugadzikana , kurasikirwa kwechido, kusagadzikana, ivo vanonyanya kushingaira.
Muvhiki yechitatu, zvipembenene zvinova zvisingabatsiri, kukwanisa kwavo kubereka kunoderera, uye havadi kufamba, saka havasi kushanda zvakanyanya.
Muvhiki yechina, zvipembenene hazvina kukwanisa kushivirira mafungu e-ultrasonic, nokudaro kupukunyuka kubva pamhando yezvigadzirwa, uye vashandisi vanoona kuti nhamba yezvipembenene inoderera zvikuru.
Kuti uwane mhedzisiro yenguva refu yekudzivirira zvipembenene, zvinokurudzirwa kuti vashandisi vasimbise pakushandisa ultrasonic tupukanana michina.
Mukuwedzera, kana iyofixed-frequency ultrasonic insect repelleryakashandiswa kwenguva yakareba, zvipembenene zvichaenderana neizvi kakawanda, uye midziyo haichazovi nemigumisiro pavari.Naizvozvo, iyo frequency kutendeuka inoshanda zvakanyanya.Nokushandura kuwanda kunoramba kuchienderera uye zvisina kufanira, zvipembenene zvinoramba zvichirwiswa, kuitira kuti zvibudirire mugumisiro wenguva refu yekudzivirira zvipembenene.
