Maererano nekutsvagisa kwenguva refu kwakaitwa nenyanzvi dzezvemhuka, umhutu hwechikadzi hunoda chikafu chekuwedzera mukati mevhiki mushure mekusangana kuti zvibudirire kubuda uye kugadzira mazai, izvo zvinoreva kuti umhutu hwechikadzi hunoruma nekusveta ropa mushure mekuzvimba.Munguva iyi, mosquito dzechikadzi hadzichakwanisa kusangana neumhutu hwechirume, zvikasadaro zvinokanganisa kugadzirwa uye kunyange kunetseka kwehupenyu.Panguva ino, mosquito dzechikadzi dzinoedza nepadzinogona napo kudzivirira umhutu hwechirume.Zvimwe zvinodzinga ultrasonic zvinotevedzera masaisai eruzha rwemapapiro ehumhutu akasiyana-siyana.Apo humhutu hwechikadzi hunosveta ropa hunonzwa masaisai emutsindo ari pamusoro, anobva atiza, nokudaro achiwana mhedzisiro yekudzinga umhutu.
Nheyo yekushanda ye ultrasound ndeyokuti mafungu e-high-frequency anogadzirwa nemagetsi ekuchinja mafrequency.Iyi yakakwira-frequency wave haisi yekupokana yakakwira frequency, asi chaiyo frequency, iyo inowanzofanana neiyo frequency yekuzunguza kwebapiro remukonikoni kana frequency inoburitswa nemaremwaremwa, kuri kutevedzera frequency.Ultrasound inoburitswa nezvikara zveumhutu.Iyo frequency inonzwiwa nenzeve dzevanhu zvakajairika ndeye 20-20,000 Hz, uye iyo ultrasonic frequency yakakwira kupfuura 20,000 Hz.Hazvina kunaka kungofunga kuti masaisai e ultrasonic haanzwike nevanhu, kana kuti haana ngozi.Chimiro chemuviri wemunhu chakaoma.Pachava nemigumisiro, kunyanya kuvakadzi vane pamuviri, uye vana vachave nemwaranzi shoma.
Nheyo ye ultrasonic mosquito repellent ndeye kushandisa isingagamuchirwi inonzwika frequency yeumhutu kusimudzira mosquito kutiza, kuitira kuzadzisa chinangwa chekudzinga umhutu.Rudzi urwu rwemasaisai eruzha harukonzere kukuvadza kumuviri wemunhu, nekuti rudzi urwu rwemasaisai eruzha harusi kutinhira.Panguva yekubhururuka kweumhutu, kana mapapiro achirova mamorekuru emhepo, simba rekudzoka remamorekuru emhepo rinowedzera, zvichiita kuti zviome kuti umhutu ubhururuke, saka dzinofanira kutiza nekukurumidza.Iri inzwi masaisai rine simba pavanhu, asi harina zvarinoita pautano hwevanhu.
