Zimatenga nthawi yayitali bwanji kuti mankhwala othamangitsa tizilombo a ultrasonic agwire ntchito?

Zimatenga pafupifupi 4 masabatandi ultrasonic repeller kuti bwinobwino kuthamangitsa tizirombo.
M'masabata oyambirira mpaka awiri, ogwiritsa ntchito angapeze kuti tizilombo toyambitsa matenda timagwira ntchito kwambiri kusiyana ndi kusagwiritsa ntchito zipangizo.Izi ndichifukwa choti mafunde akupanga ndi ma elekitiroma omwe amapangidwa ndi zida zimayamba kuukira dongosolo lamanjenje la tizirombo, minyewa yamanjenje, dongosolo lapakati lamanjenje, ndi njira yoberekera, kuwapangitsa kukhala omasuka kwambiri , kusowa kwa njala, kukwiya, amakhala achangu.
