I bought the 1500 container from my local nursery and there is no way the container contained any where close to 1500 ladybugs...it was closer to 150 half of which were dead. My 3 year old twins were overjoyed to see the ladybugs when we released them exactly as suggested, but by the next morning we only saw about 8-12 live ladybugs on our rose bushes. Try explaining this to toddlers! Great idea, but don't expect the number promised.
