Arrived late due to FedEx. The seller was understanding and offered a refund because I would be out of town when they arrived late. A friend released and most were still healthy.The ladybugs even laid eggs while I was away and I returned to hundreds of ladybug larvae still working on the aphids. And now have a few new ladybugs (note no spots on first day ladybug)Definitely will order again.

Pretty sure they were all dead on arrival. Over a week later, there are still a bunch of dots on the the tab that claimed to be the larva

Effective and easy to use. This helped address an out of control whitefly problem

I want to take back my previous bad review. I was frustrated and found the problem was with FedEx, not Nature's Good Guys. Good Guys responded very positively and will help get this order right. Much appreciated. I will continue to buy from them. These little Formosa wasps worked wonderfully last year.

We've had a very wet spring and my gardens were swarming with whiteflies. These arrived and were beginning to hatch. The conditions were not even close to ideal but I couldn't control the predicted days of rain or cooler temperatures so I simply deployed the cards throughout my gardens with very low expectations. After 11 days I saw one whitefly. I rustled the plants to see if they were simply on the undersides of leaves. One little lone whitefly took flight. An inspection of leaves showed no new eggs. I'm going to recommend these little wasps to all gardeners in my area.

Whats great about this is, that it will treat your neighbors white flys also. Once they get going they get going, but then they will always come back, but that is expected. Will buy again next season

They didn’t hatch! Don’t know why unless they were dead but never saw one. Followed the directions and everything so I’m very disappointed. Waste of time and money!

Most of the eggs hatched and they had a big impact on the white flies in my greenhouse (800 sq ft).The only problem is they are not self-sustaining. I believe they ran out of prey, once they took out the white flies, and died off.So, it appears they need to be refreshed regularly.
