We have flea beetles on our potatoes, mainly. Last year they destroyed our eggplants, so this year we are waging war against them – non-chemical warfare, of course. So here is what we do:

flea beetleFlea beetles, much like potato or cucumber beetles and other unwanted critters, can be deterred with an infusion made of nicotine. If you have a smoker in the family, gather the cigarette and cigar buds instead of throwing them out. If you have about 25 of them, boil the tobacco without the filters in water, let stew for a few hours or overnight. Stain, dilute, and spray on the foliage of your plants. Repeat if necessary.

If you do not have a smoker in the family, buy cheap snuff and use a tbsp to brew the infusion.

If you want a stronger repellent, add three cloves of crushed garlic and a tbsp of red pepper flakes to the tobacco.

    I had a terrible time with these a few years ago…For two years in a row they destroyed my Tomatoes, potatoes and were heading for my Beans…I did a little pondering and realized that they are a hard shell insect so I got out a baf of Diatamacious Earth (It can be found in most garden centers or by mail order) and I dusted the plants. You want to do othis on a dry day…

    “Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide” http://en.wikipedia.org/wiki/Diatomaceous_earth

    When the microscopic diatoms get in the joints of hard shelled insects they dehydrate. It workes like a charm!! I haven’t had a prob;em with them since…I hope this helps!!!
