And they keep on eating until the bad guys are gone, laying their own eggs in the process. When new pests arrive, fresh ladybugs will be waiting.
Ladybugs really work, and they are safe for the environment.
Ladybugs prefer to eat aphids and will devour up to 50 a day, but they will also attack scale, mealy bugs, boil worm, leaf hopper, and corn ear worm. They dine only on insects and do not harm vegetation in any way. Ladybugs should always be released after sundown since they only fly in the daytime. During the night, they will search the area for food and stay as long as there is food for them to eat. The more they eat, the more eggs they lay and the more insect-eating larvae you will have.
