Basil and Peppers...not

Just time for a gripe....my basil got aphids...as did peppers....no fun...I have such a nice indoor window for them too....I may try again...with a fresh set....but it is taking the fun out of it!  I tried a little soapy water...but the leaves wilted after that.....I tried to squash them off and wash them off...but to no avail....oh well...they are half alive...we shall see what peppers I get!
