Pre neki dan sam našao ovaj preparat (ispod je link) protiv bele leptiraste vaši.
Ovo još nisam koristio, ali deterdžent za pranje posuđa jesam, samo što treba svaki dan prskati, ali vidim da ima nekih efekta.
Nebi da reklamiram ovaj preparat, nego da vi napravite sami kod kuće.

 NEEM ULJE
U poljoprivredi
Nim ulje se sve
 više koristi u organskoj poljoprivredi jer je efikasan i ekološki 
bezbedan prirodni pesticid. Ovaj prirodni pesticid može da zaštiti 
biljku od raznih insekata i štetočina bez negativnog uticaja na korisne 
insekte poput pčela i leptira. Stručnjaci koji su se bavili ovom temom 
zaključili su da pored toga što je ovakav pesticide zdravija alternative
 hemijskim pesticidima takođe ne šteti zemljištu, a može  povećati 
prinos.
Kako ulje nije rastvorljivo u vodi uobičajeno je da se pravi 
smesa od nim ulja, vode i sredstva koje će biti emulgator u povezivanju 
ulja i vode kako bi pesticide mogao da se raspršava po biljkama. 
Najbolje bi bilo koristiti emulgator organskog porekla kao što su 
ekološki deterdženti, prah sapunskog drveta i slično. Ukoliko vam to 
nije dostupno kao zamena može poslužiti tečni sapun za ruke, deterdžent 
za sudove,…
- U 250 ml vode dodati 1 kašičicu nim ulja i 1/4 kašičice ekološkog 
deterdženta ili deterdženta za pranje posuđa, dobro izmešati i time 
prskati biljke.
 
- U 1 litar vode dodati 30 ml nim ulja i 1 ml sredstva za emulziju 
(tečni deterdžent), dobro promešati i koristiti za zaštitu biljaka.
 
- U posudi pomešati 1 litar vode, 10-15 ml ekološkog deterdženta, 
tečnog sapuna ili odgovarajućeg emulgatora, 50 ml nim ulja i sve dobro 
izmešati, a zatim ovako pripremljenu emulziju dodati na 9 litara vode i 
još jednom dobro promešati.
 
Tečnost za prskanje bilja uvek pravite u količini koja vam je 
trenutno potrebna, nikada ne koristite staru tečnost. Kao i kod svakog 
prskanja nikada ne tretirajte biljku po jakom suncu jer može izgoreti 
list.
