DEET:
DEETmushonga wezvipembenene unoshandiswa zvakanyanya, unogona kuderedza tannic acid inopinzwa mumuviri wemunhu mushure mekurumwa neumhutu, izvo zvinokanganisa ganda zvishoma, saka zvakanaka kupfapfaidza pazvipfeko kudzivirira kusangana zvakananga neganda. Uye chinhu ichi chinogona kukuvadza tsinga kana chikashandiswa zvakanyanya. Kushandisa DEET kakawanda kunogona kukonzera chepfu, saka iva nechokwadi chekuteerera kuwanda uye kutarisisa paunenge uchiishandisa, uye edza kudzivirira kunwa kwenguva refu uye kushandiswa kakawanda.
Nheyo inoshanda yeDEET ndeyekugadzira chipingamupinyi chine utsi chakakomberedza ganda nekuputika, izvo zvinogona kukanganisa kupinza kwekuputika mumuviri wemunhu nemakemikari ekuongorora antennae yeumhutu, zvichikonzera kusagadzikana kumhutu uye zvichiita kuti vanhu vasarumwe nekurumwa neumhutu.
Mushonga unodzinga umhutu:
Inodzinga umhutu, inozivikanwawo se ethyl butyl acetaminopropionate, IR3535, uye Yimening, ipurasitiki uye inodzinga zvipembenene zvine spectrum yakakura, inoshanda zvakanyanya uye ine chepfu shoma. Hunhu hwemakemikari hwe ester inodzinga hwakagadzikana uye hunogona kushandiswa mumamiriro ekunze akasiyana. Panguva imwe chete, ine kugadzikana kwakanyanya kwekupisa uye inodzivirira ziya zvakanyanya. Umhutu hauna simba.
Pfungwa yemushonga unodzinga umhutu ndeyekuti umhutu hunoshandisa nzira yekunhuhwirira kuti uwane chinangwa chine hwema hunoburitswa nemuviri wemunhu, zvakaita segasi rinobuda uye hwema hweganda, uye basa remushonga unodzinga umhutu riri mumuviri wemunhu. Pamusoro payo panoita chipingamupinyi, nokudaro zvichibvisa hwema hwemuviri wemunhu, zvichimisa hurongwa hwekunhuhwirira hweumhutu, uye zvichikanganisa kunhuhwirira kweumhutu, nokudaro zvichiita kuti humhutu hudzinge.
