Regarding your webpage about pickleworms, the last sentence in the article says that Bacillus thuringiensis won't work once the caterpillars are inside the plant tissues, it’s too late for treatment, so spray early and spray often. But I've read that BT is systemic, so won't it kill the bugs even if they are inside? https://www.gardeningknowhow.com/edible/vegetables/cucumber/treating-pickleworms.htm
This fact sheet from the National Pesticide Information Center mentions that different types of Bt are engineered to affect different types of insects. The kind of Bt that is effective on pickleworms targets the larvae. Because pickleworms lay their eggs directly on the foliage of a plant, it's important to spray the Bt "early and often" as the article says, so that the pesticide can kill the larvae BEFORE they mature enough to tunnel into the flowers, vines and fruits.

Hi, I've recently seen spots in the leaves of one of my succulents. I thought it was just a problem with this specific plant. After a few days it had spread throughout the garden including my draceanas. I'm not sure what they are and what to do? Please see attached photos. These plants are located in Australia and it's winter season at the moment. Can someone please help? Thanks Len
This looks like a Scale infestation.
Use Neem Oil on your plants.

What is the best way to get rid of aphids especially & also spider mites? Thank you!
A strong spray of water will blast aphids off of plants but large numbers will return. Thus an insecticide listed for the control of aphids must be used. Spider Mite control takes the use of a miticide as insecticides will only kill off all of their natural enemies and make the situation worse. I used Avid and Floramite to control the mites. Both are costly if you buy an entire bottle on your own. I go to Ebay and buy smaller amounts from gardeners that have purchased the entire bottles and sell off some in smaller amounts at an affordable price for the small typical gardener like me. I spray the Avid once my roses and other plants have fully leafed out in the spring. Then if I see a problem get going with the spider mites, I will spray again only this time using the floramite as mites can tend to build up a resistance quickly if the same thing is used to often.
This is more of a how to then a question, you guys left out a huge and very simple ways of dealing with these lil destroyers 1st the moth either lays or drops it's eggs on the plant"tiny of white or gold egg"they luv to do it in the preflower because as it grows it the egg is encapsulated and hidden well then it hatches and starts eating it's way up and down ur flowers and stems keep plants netted with fine screen to keep the mother moth out in the 1st place.if u really want to see how an egg is planted watch a butterfly or moth when they land you will see them lay the egg it's sometimes on a tiny lil string or a super tiny lil ball.
Thank you for your information and I will pass on to the Editors.

Can you identify the attached pests and advise on eradication? I have them on cotoneaster lacteus, sedum and geraniums. Thank you.
I could not see the attached photo. Did it upload properly? Maybe you could describe the pest/damage to me. I recommend a product by Foxfarm, called Force Of Nature Miticide. It is all natural and VERY concentrated. I have used this on many pests, and it takes out even the most aggressive infestations, including russet mites. or, you can make your own using garlic, cayenne pepper, rosemary oil, neem oil, and a small amount of vinegar. Please contact me back if you have any further questions. Thank you
Although I can (will) fence in my vegetable garden moving forward, I can not fence in everything. They ate my peonies to the ground (I thought they were deer resistant )! My climbing Roses too! What can I do?
If Deer are hungry they will eat anything, even if it is Deer resistant.
This article may have some tips for you.
