Manhattan, KS— A natural way to keep gardens safe from hungry pests is to employ the help of praying mantids. K-State entomologist Raymond Cloyd said this top predator of the insect world can be beneficial to a home garden.


“They eat anything they can grab onto with their raptorial front legs,” Cloyd said, “including flies, crickets, moths, butterflies, wasps and caterpillars.”


He said home gardeners can keep an eye out for praying mantis egg cases between November and April. They appear as a hardened, Styrofoam-like egg case, and can stick to branches, stems, walls, fences, sides of houses and eaves.


Just-hatched mantids, called nymphs, will emerge 3-10 weeks after the eggs are laid.


“Nymphs that emerge in spring resemble miniature adults,” Cloyd said. “However, not all the nymphs will survive to become adults because they are susceptible to predation by birds, toads, lizards and predacious insects.”


To ensure the garden has a few praying mantid guardians, their egg cases can be preserved. To do so, Cloyd suggests:


If no praying mantid egg cases can be found in the garden, Cloyd recommends purchasing them from garden centers, nurseries or other mail sources.


Cloyd and his colleagues in K-State’s Department of Horticulture and Natural Resources produce a weekly Horticulture Newsletter with tips for maintaining home landscapes. The newsletter is available to view online or can be delivered by email each week.
