The Pests of Summer

An adult periodical cicada sitting on a leafAfter living underground for nearly two decades, some noisy, uninvited guests may be crashing your next barbecue. In fact, millions of them have been swarming through parts of the East and Midwest since mid-May, 2004.

Looking for mates and places to lay eggs, these visitors are periodical cicadas -- insects that spend 13 or 17 years (depending on the species) underground in their early years, feeding on sap from tree roots. When the nymphs emerge in late spring, they transform into flying adults, then buzz off to complete their life cycle before they die in about a month.

Cicadas are really noisy bugs, so if you live where they do you may want to keep a pair of earplugs handy. Their songs are cricket-like, and they're loud because they travel in large groups.

Cicadas won't be the only insect to bother us this summer, though. Pests such as mosquitoes, ants, termites, ticks, spiders, and fleas, will also crawl, fly or eat their way into our homes. Some can harm our health, and others can damage property.

This week's lesson will help you defend yourself and your home against some of these pests. You'll find out what kinds there are, how they live, and what you can do to keep them away. You'll also uncover the cicada life cycle, and see how to collect their old skins!

Gimme Some Skin

Begin with a stop at Cicada Watch 2004, hosted by the College of Mt. Joseph in Cincinnati, Ohio, and read the introduction on the home page.

Which states will see the most cicadas? What time of day do the nymphs crawl out of their shells? What are the three species taking flight this year?

Uncover a few more facts at the Cicadas FAQs page. For example, Do both male and female cicadas sing? When will the cicadas emerge? What is a brood? Which brood number is the one emerging this year?

Also, check out the Cicada Calendar to get an overview of their life cycle's timeline.

First read about their hunt for annual cicadas then about their hunt for periodical cicadas. What kinds of differences between the two types of cicadas did they discover? Were there any similarities?

If you have time, you can solve cicada mysteries with Ethan and Aaron, or see what else they found.

Have you ever found cicadas, wasps, beetles, or other insects, alive or dead? Did you ever find more than one species in the same area? If so, how do you think each species survived there? Identify each species and investigate their life cycles to solve the mystery!
