There's a lot of information out there on what will and will not work on psyllids, and Neem is one that's been mentioned time and time again, however there are conflicting reports on its effectiveness. I've seen several instances where people have said it's basically ineffective, and what little it does requires it to be sprayed at too-frequent intervals, and others where people seem to think it's doing something ("Sprays containing an extract of neem oil [Greenlight Neem Concentrate] help control a variety of garden pests and may also work on tomato psyllid," according to the Ventura County Master Gardeners). I also came across an article about neem granules, but I've never seen them sold before, and they supposedly need to be put into the planting hole, so that's out at this point. As far as the scaley nymphs go, they don't come off all that easily. They're not like aphids or whiteflies in that regard. And the eggs are even harder to get off. I've rubbed them, pinched at them, sprayed them... they do not come off. I guess I could take a magnifying glass and an expensive pair of slant-tipped tweezers to squish them all, but that would take me years to get them all. Different methods of control work with varying degrees of success, but after doing battle with these guys last year and having them take out my entire tomato crop, I want to use whatever's going to make them die the fastest, provided it doesn't also make my household pets die. I'm not overthinking anything, really. I'm going on what I've read from various sources, and that's all I can do, since it seems that there are no experts on tomato psyllids roaming around doling out advice on what's guaranteed to kill them all off. Even the commercial growers haven't figured out the best way to stop their crop loss with all of the crazy insecticides they have access to, last I read, and I'd imagine if anyone was going to try everything under the sun and come up with a solution, it'd be those with money to lose, so I'm doing the best I can with what I have. Oh and Ray, as far as the Sevin goes, I've come across several recommendations against it. It kills off everything, including any bugs that could be beneficial in eating the psyllids. And the only thing I've read about being proactive against them is the one weird article I came across talking about the neem granules that seemed more like an advertisement than anything scientific. If they want to eat your plants, it doesn't sound like there's must to deter them, but if you find something, let me know.

I agree that they are red aphids and they are sucking the good from the plants. A forceful spray with cold water helps or try insecticidal soap. Mix with water as per package instructions and spray the plant. The soap will also kill any eggs and it is completely safe. Then watch to see if you've missed any.

Hi friends, I'm struggling with a similar problem and could really use some advice. I apologize for how long this is, but it's kind of a specific circumstance. My fiancée and I just moved into a little apartment with a lovely little deck that we'd love to be able to use and have friends over on. Unfortunately, the frame of the back door that leads out onto the porch is also the entry point for what appears to be a pretty large nest of honeybees. We have no way of knowing how old this nest is because we moved here from out of state (I've just started grad school in the area) and only discovered the bees when we were moving in (mid-august). The bees certainly aren't aggressive, but I have a crippling fear of all things-with-stingers because of a bad experience when I was very young (I've been stung since then in my life; I know it's not terrible, and that as long as we leave them alone it's highly unlikely, but when is fear ever rational or easily controlled?). I'm beyond disappointed we can't use our porch for this reason��"even opening the back door before they've gone to sleep causes a lot of stress and anxiety��" because it's one of the reasons we chose this place, but much MORE IMPORTANTLY than that, as the weather is starting too cool down here, they are finding their way into the warmth of our living space now and then. THAT I am completely unwilling to deal with in any capacity. Bees are completely unwelcome inside my house. We simply CANNOT tear apart our walls from either side because we do not own this building (nor are we financially-eqipped or have the time to do so), and while our leasing-management was great about sending an exterminator (twice) when we complained, all he did was spray around with some general pesticide that of course didn't even get into hive or probably kill more than a couple of bees if any. From the research I've done, no exterminator is equipped to handle this anyway. We're only going to be here for a few years while I complete my degree, so at this point, I'm not looking for ways to get rid of or move the bees, but ways to minimize our interactions with them so we can just deal with them as a temporary problem and I can function a bit better, with less anxiety issues (since our leasing-office seems disinterested in actually taking care of them, they can deal with every tenent they ever have complaining about them, I guess). We can't locate how the bees get inside the house so we haven't been able to seal it, but if there's some sort of spray or something we can use generally on our walls and in the area to discourage them from coming this direction, that'd be great. Recommendations, traps, or other ways to lure them away from the door/minimize their presence on our porch would also be great, but at this point, the only thing I NEED accomplished is to keep them from coming inside. I am unopposed to any methods that involve killing them. I truly wish I didn't have to, but there's simply no way we can get them moved. When they're outside, that's their business, but bees that come inside my house and violate my safe-space feeling have forfeited all empathy I have for them.

Image is too small. However you can apply a per-emergent herbicide such as XL or Amaze mid-Feb., mid-May and mid- September to prevent them germinating in the first place. Here is a link that might be useful: XL
