goede service, goed behandeld

It simply works. I had lots of black aphids on a wisteria and a cherry tree. After one week, they are now almost gone of action of the ladybug larvas (which I can still be growing and going around on the plants). I has been a great experience for me, also understanding the interaction between aphids and ants (that I removed before treating the plants, as suggested) and as well as how ladybug larvas hide under the leaves of the plants and distribute over the branches every day. They walk a lot, searching for food.
FYI I found your company by walking by an Intratuin shop and seeing one of your flyers.
Sorry if this is in English, but it would have taken me too long to translate it in Dutch.
VerbeterpuntenI find that the small plastic box where the larvas are delivered is not ideal. There is some space between the two parts composing the box, leaving space for the larvas to crawl in (which can result in accidental crushing of the very small larvas. Yes, there are 50 inside and one cannot hope to save the all, still...).
I would also suggest to improve ideas on how to deliver the larvas in the plant. I did what explained (hanging small paper sacks with some green plastic chord on the branches of the plants) but I found that moving the larvas with a small sharp knife is also extremely effective (also to move larvas from one place to another after a few days, when perhaps there a too many on one branch and too little on another). It could be a good idea to shoot some videos and to give a weblink to the customers.
Another thing I did was putting the larva in large transparent container when they arrived (like Tupperware, about 20cm wide) and place a few leaves with aphids inside. It was interesting to see it took one day for the ladybug larvas to understand that was food. Once I saw that confirmation, I moved them outside (third day of the delivery) and they made the magic happen. They are extremely voracious. Impressive to see. Also, how fast they grow in a few days.
