Do not know your bugs, but have a few ecologic ways which may help
Pyrethum... it is from a special crysantenum... here it works great in the veggie garden... or rather it did work good, now it is impossible to find, think Bayer once again have got it blacklisted for uncomercial use..so I'm sure there will be a Bayer product using it in a few years...
or my fathers old advice... put old used cicars in a mix of water and let it stay for a few days.. then spray
Wait a week before you eat the veggies and make sure they are well water washed before you pick them... do not think my father cared
