I bought some spray at home depot called Ortho ecosense brand
It works but I need something to keep bugs off for days, it seems like I have to spray ,my plants too much to kill all the aphids. With ever new bud I get new aphids! i used bayer and loved it but I am not sure if the plants I have are old enough ? I saw kris's post and it made me not buy bayer until they get older.
The smallest is rockets red glare which I just bought 4"

I am reading more on the label Ortho , it says do not spray more than 10 times per season ..... This season just started and I have used this stuff about 5 times already  . I also says do not wet plants to the point of drip run off..... umm this spray bottle does not mist and I get run off all the time. My plants seem find but I think i will start misty them with water to keep the oil from overlaying the leaves |

HI Kerry,
Aphids can be persistent and hard to eradicate. Ants often bring them or their eggs onto plants so that the aphids will produce honeydew from plant sap that the ants then collect as a food source. Amazing how they practically "farm" aphids. They will defend them from other predators, too! Thinking like that, what would a vet do? For sure control the ants if you see any of them near the plants.
By far the easiest and most effective way to get rid of aphids is to treat the hibiscus systemically with imidacloprid. I wish we could make some of the Marathon 1% granular available - very safe and easy to use but you need to have an Operators ID to get it. The only equivalent product I am aware of is Bayer Tree and Shrub which is intended for drenching into the root zone, not for spraying. The systemic effects last for months and will keep the hibiscus free of aphids and whiteflies with one treatment. You do want to get the dosage right if you use it but if measured carefully can be used even on small hibiscus.

Charlie Well We have no ants in my apt nor on my balcony , I checked my plants daily the only bugs I see is the aphids, Spiders ( because of the bugs  ) I will go to home depot and see if I can get the bayer tree and shrub insecticide. Thanks for the info I will post updates if there is success in this battle. The main thing i do with the ortho spray is just spray the new bud since this is where the aphids are nesting. |

Charlie is right about the dosage. I just can't seem to get it right with Bayer Tree and Shrub. I used it once for a bad aphid infestation, and followed the label instructions. It didn't do anything to the aphids. I doubled the dose and it killed the aphids, but almost killed all my plants. This was last year. I put some on my Island Girl several days ago because it has a small colony of aphids on one of the growth tips, and it hasn't seemed to do anything to them. I'm not going to try a double dose... I will wait a couple more days and if nothing changes I'll just prune that tip off. I HATE aphids...  |

I looked over my plants today and notice that Gator pride is being attacked more than the other plants. I killed them off of voodoo last week and my others but gator pride seems to be their favorite meal !

Hi Darkhorse,
The drawback to this product is that it takes a week or more to work its way into the plants systemically. If there is a bad infestation it gets worse during this time but once the imidacloprid kicks in its bye bye aphids, whiteflies, etc. Please do wait at least a week before dosing it again. The directions for dosage are not good because they are talking about trees and big shrubs but I worked it out once before for hibiscus and need to do it again so it is posted for anyone to try.

Hey Charlie, My Island Girl is now covered in aphids, but they're all dead.  I do with they would say that it takes some time to work on the bottle, or maybe they did and I didn't see it. I didn't double dose my IG because of what I learned from doing that to my plants last year. I also realized that I didn't have the Bayer Tree & Shrub. I had the one for roses and shrubs, but it killed the aphids anyway. I hope I caught it early enough so my other plants aren't invaded. Jordan |

Hi Jordan,
At least it worked! The Bayer Rose and Flower Insect Killer is intended to be sprayed on the leaves and it is a good remedy for aphids. It has the same active ingredient - imidacloprid - as the Bayer Tree and Shrub. The difference when spraying instead of drenching of the soil is that the systemic effect does not last as long when it is sprayed on the leaves. Drenching the soil with the Bayer Tree and Shrub can provide protection that lasts for months, while the spray lasts at best for a few weeks. The spray gives much faster knock down than the drench so that is a plus for it. The newer product, the Bayer 3-in-1, has the advantage of instant knock down from a pyrethroid chemical and the longer lasting systemic effect from the imidacloprid in it.

I haven't used the 3 in 1. I will probably try that next time I have to deal with aphids. Does it kill mites too? I think the rose Bayer I had was a drench. It didn't have a sprayer and I used it as a drench. I might be wrong about which product it was. I already threw away the bottle. |

It can be confusing with all these products. If you had the concentrate of Bayers Rose and Flower that would be too strong to use without diluting it. Anyway, if in doubt you can always post a question here before using one of the many similar products.

That's good news! The Bayer 3-in-1 contains imidacloprid which is what you need to get the aphids. Imidacloprid is systemic both as a spray and as a drench, although the spray does not last as long as the drench.

I made a mistake and bought the bayer rose and flower spray  . So far its working , I been a little bit cautious with it so I have not sprayed it too much. I got some horticultural oil and mixed 2.5 table spoon in one gallon as directed. I will see how it goes. I have LADY BUGS that visit my plants  So I know they are loving the aphids. Would the horticultural oil harm the lady Bugs ? |

The Bayer Rose and Flower Insect Killer spray that you bought is just fine for aphids and whiteflies. The 3-in-1 is the same but also has a miticide and a fungicide so we recommend that one instead but the Rose and Flower will take care of aphids and most sap sucking insects.
Mixing with hort oil is good because that will also take care of any spider mites that might be lurking. Spider mites are stimulated to lay more eggs by the active ingredient in Bayer Rose and Flower so the hort oil is an excellent addition to this spray that I would use every time I sprayed the Bayer product.
