Schlumbergera Truncata (Thanksgiving) and Spring (Easter) Cactus problems

Hi, I have several small Cacti and they are not doing well. First, they started with brown spots that looked like Mite damage but even with a high power magnifying glass, I never saw one Mite. I sprayed several of them with Alcohol a few times and I'm not quite sure if it helped or not. I put several of the problem plants outside for the Summer and they are doing better but now I have one with new growth but it has developed red spots on the older clades. Previously, the plant was exposed to too much sun indoors and turned red. They are now outside with minimum sunlight on a covered porch. I'm thinking they could have a virus? Also, I had what I think was a Fungal issue. See pictures attached to see the Fungal, Mite damage and the red spots. Thanks, Cathy

What are these?

Can someone please help me!! I live in a newly built development/apartment and ive recently had an issue with tiny black bugs on my ceilings at night (attracted to light) and have also predominately found them on the window sills and sometimes in the bathroom. They also appear near my ceiling vents and even in my bedroom. My apartment is not that big, it’s 825 sq ft. At first I thought that they may have been fungus gnats but I’ve tried the apple cider vinegar trick to no avail. These bugs do fly and are tinier than an ant. Last night I noticed possibly some larvae in my pantry and now I’m starting to believe that these may be flour beetles and are multiplying. My property management took a glance and couldn’t see anything, that’s how tiny these bugs are but I know I’m not crazy and I’ve now seen what looks like their casts. please help!!!

CREPE MYRTLE TREE CARE

YES about 3 weeks ago I purchased a MUSKOGEE Crepe Myrtle. I checked and this should be winter hardy for the PA area. I live in Catawissa. This tree is about 8' tall and was balled where the roots etc were 22"x24" It has started to bloom so I believe it has SETTLED IN WELL. I have not mulched it yet bc I was contemplating what is BEST and have done some research...BUT a friend tells me I should put small 1" river stone around it to help retain some of the moisture and then mulch with SOME peat moss topped off with Pine Straw. Im just reluctant. PLEASE ADVISE !!!

Boxwoods dropping leaves on one side?

We’ve had these planted for about 5 years and all of a sudden in the past few weeks they’re losing all their leaves on only one side?? Pics are: fronts, close up of leaves dropped, close up of the back side of the worst of the three bushes.

Article: Parasitoids - Tachinid Fly (Diptera) How to Attract

Hello, I represent some monarch butterfly "growers" in western Pennsylvania. We have been having issues with the Tachinid flies killing up to 90% of the monarch caterpillar population. This is increasing around the state and probably nationally. Please do not promote the attraction or in anyway try to get them to multiple. They are only beneficial in a small way. You have a large audience can you please get this information out there? Dan Giles
