Studies have shown that storing beneficial insects under cold temperatures has a terrible effect on them. I mean think about it: if you were constantly in a room with freezing temperatures your body is going to start weakening. Same thing happens to the insects. Some may even develop what the experts call "non-responding syndrome" in which, as the name indicates, the beneficial insect becomes unresponsive even if the prey is right in front of it (more on this is available here). The problem today is that most beneficial insects are imported from overseas, which is impossible to do without keeping the predators under cold temperatures for long periods of time. This is why we at GrowLiv produce beneficial insects locally to ensure high quality fresh products. Our insects are scientifically proven to have longer lives, faster reproduction cycles, and a better searching capacity compared to the leading suppliers. And get this, it's all available at matching prices.
