That because not all insects are bad. There's butterflies, earthworms, friendly tarantulas, bees (if you leave them alone), ladybugs, and other harmless bugs. But there are some nasty ones like mosquitoes, termites, deadly spiders, bedbugs, and other nasty and naughty bugs. So the exterminator is bad when he killed innocent bugs, but good when killing harmful bugs.
