Bed bug?

I found this on the baseboard next to my bed. I couldn't find any others. I woke up with two bites this morning but have no blood marks or spots or casings on the sheets or mattress cover. I did not see others in the slats or bed frame joints. I have never had bed bugs before. I could not get a better photo, but I did take a video of it walking on the wall before I trapped it with tape.

Mountain ash turned orange

Can someone tell me what is happening to my ash tree? There are a few new growths at the very top green leaves. I’d hate to lose it!

Found these ...Are these bed bug nymphs?

I have been fighting an infestation, and thought I was done. I put down interceptor traps for a few weeks and found these. Are they bed bug nymphs? I have a video that shows them better.

Rhododendron, disease or insect problem?

My large 15 yr old rhododendron suffered from the past winter, the entire top 3/4 died. It was cut, leaving only the undamaged bottom. It flowered but now all the new growth is deformed & dying as it forms.
Is this from a disease, insects and should I remove the entire plant?

Is this a carpenter ant?

I've been seeing these large black ants in my home. They are single and measure between 1/4 and 1/2 an inch. Hard to see where they are coming from as they are one only and so no ant trail. Are they carpenter ants?

Head cut for 1st level espalier lateral branching


I've attached a photo of one of my Asian pears trees. I would like to train it into espalier. Would I head the tree back to the red line and that would encourage 2 circled parts to grow as the first level (1 left, 1 right) lateral branches?
