Can anyone help me identify these insects contamination in my garden ?

I happen to like using diatomaceous earth - natural, kills pretty much any insect that crawls across it within 24-48 hours (even bedbugs!). The only downside to this stuff is the fact that you have to reapply when it gets wet as water renders it completely ineffective.

neem extract (suggested dosage by brand), potasium soap (5-8g per liter) 1ml of pure cinnamon extract per liter -leaves-, 3 days later use a potasium silicate based product (as brand suggest) -leaves-, 7 days later repeat with the neem extract & soap & cinnamon -leaves 5 days later use silica trough the roots, 7 days later use again neem & soap & cinnamon. 21 days is the the average time to make a complete cycle, if you do it right you'll kill them and interrupt their cycle. Neem act by contact & ingestion, the soap will disolve the exoskeleton and will help the neem to make a way in their bodies, then sílica will make the surface of the leaves stronger and will act as irritating and it even work by ingestion & contact by the action of the soap and finally the cinnamon make an interruption in their sexuality process ghosting their pheromones and as neem they'll stop eating by its action. If you're in the first 2 weeks of flowering you can go for it but if you're advanced... you'll probably need to go to a chemical solution and quick as you can, most of them need 4 or more weeks to disolve their compounds.

use, neem oil , i tryed for my outdoors and worked. 10ml per 1 liter .

I can tell you soap is not strong too beat them. Peace

Hello buddy it seems you red spiders. They can be white, yellow, red etc . you can eliminate them naturally with insects predators who will eat them or you can beat them with chemical insecticide (systemic).i advise you to use systemic insecticide because they are really resistant . use spidermite Control or an other brand and follow instructions. Good luck

Mix a little dawn soap in water and spray the under and upper part of the leaves.
