Yesterday I had several on two different cuphea schumannii plants. So last night I sprayed both plant's leaves well with a soapy dish spray. Today Ive seen none on the schumannii but realized that I had not sprayed david verity. So at first I could not see JB on the david verity but after spraying it down with the soapy spray out they came. With the spray makes them unable to fly away so its easy to just pick them off and drop in my soapy bucket. In addition you just might be taking care of any potential mites on said plants with the soapy spray.

So do you have a recipe? What about our hummer friends? Do they make a funny face when they taste soap?
Seriously Steve thanks for the heads up?

All I know is it seems to work. I sprayed it last night and again today. If the hummers get a bad taste from it I have plenty of other plants in bloom they can use. Just a few drops of dawn in a quart sprayer seems to do the trick. Get those leaves soapy.

For what its worth to anyone, today I observed a hummer going over many of the david verity blossoms without a hitch. The same plant I spray heavily yesterday with the soapy spray.

Steve, this may seem nit-picky, but Dawn is a detergent, not a soap. Would perhaps real soap, like Ivory [dissolved in water] as we used years ago be more effective?

I would be very nervous about spraying such a concentrated detergent on flowering plants that hummingbirds were going to feed from. I concur with Nancy, a milder soap would seem more safe to use.

Luckily, our Japanese Beetles have only found a lone Jewelweed plant so far. Cupheas are devoid of them---I'll take it while it lasts!

Thanks and you may be correct. The dawn I used is ultra original scent most likely less detergent than others. Just the same I will keep your comments in mind although liquid hand soap is not something I buy I would need to go out of my way to get it. For just maybe one week out of the year , pretty iffy.

Steve, 'liquid hand soap' is likely detergent as well. There is a chemical difference between soap [which is a rather simple compound] and detergent [which is not simple]. At least it was when I studied chemistry a few years back.

To make authentic soapy water, one would take a container of water and shave some soap into it, allowing some time for the soap to dissolve. It has been quite a while since I looked, but soap used to be readily available at most supermarkets.

As far as I can see, the concoction you produce may be safe for plants and birds, but it isn't soapy water.

All I know is if they eat all the plants I will be very upset..So I am willing to try anything.

To my utter shock today when checking david verity I found these guys piggy backing and having a ball.
