Hand Me the Raid

Great. A new class of insect has been discovered - the gladiators - bringing the total number of classes to 31. Prior to this, the last new insect class, rock crawlers, was added in 1914. All of the 1.2 million identified species of insects on the planet belong to the class of flies, twisted-wing parasites, scorpionfiles, fleas, moths/butterflies, caddisflies, ants/wasps/bees, beetles, lacewings/antlions, dobsonflies, snakefiles, book lice, bugs, lice, thrips, stoneflies, webspinners, angel wings, cockroaches, mantids, termites, gladiators, earwigs, rock crawlers, walkingsticks, grasshoppers/crickets, dragonflies, mayflies, silverfish, jumping bristletails, or aphids/cicadas. My question is when will Ortho have a spray for them?

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
