Lye and aphids

Hey everyone, I have a question. Has someone ever tried, or has any thoughts on using lye as aphid killer? I have tons of wood ash and want to try using the lye as aphid insecticide. All i know about lye is that it can do harm, as it is very strong a solution. So, can someone tell me how can I measure, should I dilute it with water etc. Any thought is welcomed. Thanks in advance. Cheers

Vase, that is an interesting question and I am looking forward to what comments everyone makes.

Thanks a lot, Anne, will read them

Vase, I often skip the middleman and dust plants where I have bug issues with wood ash (usually, beans at the end of the season that are getting hassled by spotted beetles and stinkbugs, which always lead to mold). Because the leaves are in bad shape already i don't worry too much about them getting burned. I've not tried this for aphids (in my garden, aphids appear with drought, if I really feel bothered by them I spray a soap/garlic spray that seems to take care of the situation pretty quickly).
Let us know what you end up doing!
