At least 50 ladybugs were still hanging around this morning. YAY!
Here are the tips that I used to keep them from taking off to the neighbor's yard.
1. Put them in the fridge for at least an hour. Mine were in for 3 hours. They go dormant in the fridge.
2. Water your garden first, then spray sugar water in your garden. The ladybugs will eat the sugar water until they find the aphids.
3. Release the ladybugs at dusk or when the sun is not out. I released my ladybugs around 6pm, it was cloudy and set to rain.
I can't wait until next year to do it again!
