Nyaya huru yakaongororwa muchidzidzo ichi nedzimwe ndeyekuenzaniswa kwehuwandu hwemishonga yezvipembenene inoshandiswa munzvimbo dzakasiyana siyana dzekuongorora. Sezvakaratidzwa muMufananidzo 2b, pasinei nenguva yakatarwa yekupfapfaidza, huwandu hwekupfapfaidza hwakasiyana pamhando dzemagaba eaerosol, zvichigona kuratidza mutsauko mumaitiro ekugadzira (semuenzaniso, kumanikidzwa kwemukati, kushandiswa kwepropellant, chimiro chemuromo, nezvimwewo). Uyezve, kushaikwa kwemidziyo yekupfapfaidza iri kure iripo kunotengesa ine kushanduka kunodiwa muhurefu hwekupfapfaidza kunoderedza kushandiswa kwayo mukuongorora hukama hwemushonga nemhinduro yekudzora umhutu. Kupfapfaidza nemaoko kuburikidza nemakavha ekuyedza kana mahachi ekuwana (kana aripo) kunogona kutungamira mukuchinja kwehuwandu hwemushonga. Kutaura zvazviri, zvatakawana zvinoratidza kudiwa uye kukosha kwekuderedza manyuko aya ekuchinja. Kune vanhu veAedes aegypti vasingapindi, takaona hukama pakati pemushonga weaerosol uye kusarudzwa kwekupedzisira kwehutachiona kana kuramba (Mufananidzo 3b). Zvakanaka, huwandu hweaerosol hunofanirwa kuenzaniswa mumagiramu echinhu chakaputirwa panzvimbo pehurefu hweaerosolization kuti zvive nyore kuenzanisa pakati pezvidzidzo zvakasiyana.
RCAD inopa imwe nzira yekutsvagisa mune ramangwana inoderedza kukanganisa kwekuchinja kwemaitiro. Kunyangwe takaona kuti kurongeka kwema spray e aerosol hakugoneki, takaratidza kuti huwandu hwe aerosol hunounzwa kuburikidza nemakani akasiyana e aerosol hunogona kuverengerwa nekuenzanisa kureba kwe spray (Mifananidzo 2b, 3a). Kurongeka kwakadaro kwehuwandu hwe aerosol mukamuri chero ripi zvaro rekuyedza kwakakosha pakuvandudza kudzokororwa kwemhedzisiro.
