Having lotsa bugs around means that your enviroment is healthy.
Bugs attract birds, which are nice to look at and hear sing. However there are sometimes too many birds, like Starlings. Kill them, they are not native to here. Kill feral cats; They kill the birds that kill the bugs.
If bugs bother you, don't ever move to where I live. Bug heaven down here.
Of course there are bugs that do, potentially harm us but generally it's not nice to fool Mother Nature.
Of course I'm sure that having one bug killin' bottle of something in your yard will not upset the balance of nature but folks tend to get bent outta shape when it comes to unwanted bugs. People get paranoid for no reason when it comes to insects.
Watch the Animal Planet for your TV viewing instead of Comedy Central, speakin' of animals... :(
