What are these on my apple tree

Just checked the lable, you can use it on food crops, spray now and then again 14 days later.

 

I've got their "ultimate bug killer" says not to spray after 14 day before harvest

Just used it on my Gooseberry bush to keep the geese off

 

Went the flame thrower route, waited until well dusk, so minimal "good" insects about, then gave them a roasting, strangely thought of doner kebab from the smell, haven`t had one in years when I could get a good one.

 

Just for info, as they've been roasted.....Any and all caterpillars (but not sawfly larvae) can be treated with Baccillus thuringiensis. It's a bacteria in powder form that is specific to caterpillars and so totally harmless to other insects, animals and humans. You mix the powder with water in a sprayer and spray the affected plant(s) then the bacteria gets to work on the caterpillars. Very useful against processionaries, box moth, cabbage whites etc. Can be used as a preventative treatment too. Probably marketed in UK as treatment for specific problems, as it is here, but it should say in small print on the box if BT is the active ingredient.

 

The problem with those kind of remedies is having it readily available, by the time I had scourced it, shopped for it, on-line probably, they would have caused untold damage to my apple tree, probably dispersed to other plants, I would then be hunting for the dear little darlings.
