Aphids On Long-Beans

Aphids are easily one of nature's greatest nuisances. 

If you grow a backyard garden, then you know they're a headache — there's simply no way around them.

They're ever-present from late May straight through the end of the season. They love to get onto flowers, vegetables, vines, crepe myrtles and especially my long beans.

In fact, if I didn't love eating my long beans so much, I’d still plant them—but strictly as a trap crop. Aphids are drawn to those vines like a bear is to honey.

Fortunately, even though they're abundant, they're fairly easy to get under control. And honestly, that's a good thing because, believe it or not, aphids are born pregnant. They multiply so fast, you'd swear they can double their population in a matter of days.

These tiny pests pierce the stems and the developing fruit, drinking the fluids and sucking the literal life out of your plants. But it doesn't stop there. As a thank-you present for providing them with a feast, they leave behind a sticky, sugary secretion called "honeydew"—a nasty, disgusting residue that happens to be an unbelievable delicacy for ants (especially fire ants).

In fact, many times, one of the best ways to identify an aphid infestation is by watching the line of ants going up and down the plants gathering up the honeydew. The ants farm the aphids for this prize and they'll fight off the natural predators in order to keep it. 

Wasps, hoverflies, ladybugs — they don't stand a chance. 

Ladybug eating Aphids

As soon as one of the good guys lands to eat an aphid, it immediately gets attacked by ants and is driven off.

So how do you get them under control? 

This is where the debate starts 😉 I'll tell you what kind of advice you'd normally get, and then I'll tell you what I usually wind up doing. 

If you ask the question, you'll receive one or more of the following responses:

Neem Oil, Spinosad, Pyrethrin, Bt, blast of water, and believe it or not, I've even seen Epsom salt listed.

What I do? There's only one thing listed there that I would do, and that’s blast them with a stream of water — as hard a stream as the plant can take. 

Now, to be fair, Neem oil works on soft-bodied insects, but it takes a few days and you have to reapply it after a rain. The others listed? Yeah — hard no!

Bt doesn't work on aphids, it's designed to stop the leaf-eating crawly things like caterpillars. Spinosad and Pyrethrin could work, but like Neem, they would have to be reapplied after a rain. Also, if you spray them at the wrong time, they'll affect the pollinators and the good guys you're trying to draw into the fray to help out.

Epsom salt? I honestly don't even know where to begin on that one 🤦‍♂️

Aphids initially get on your plants by flying onto or crawling over from a nearby plant. They're extremely slow moving once they're there and a blast of water from the hose knocks them into the dirt very quickly and very efficiently. Once gone, they don't find their way back. 

Before & After Spraying With Water

Down here with the heat and working with containers, I find I need to water at least every three days or so. That's more than enough frequency to blast them every time with the hose and keep their numbers low enough that I don't have too many issues. If nothing else, it keeps them low enough that they don't draw ants. That means the wasps, ladybugs, and hoverflies get to do their jobs and they don't get eaten in the process.

The best things about using just water? I'm not using chemicals, it isn't costing me a ton of money for something I don't need, and I'm out there with the hose anyway. Five extra minutes and the problem is solved.

Now, you're more than welcome to use whatever you see fit, but take it from this old guy that loves his beans — especially pest-free beans — the water works! And for those who haven't seen it, here's my full take on using chemicals in the garden:  Chemicals in The Garden - Do We Really Need Them? — It explains my whole philosophy.
