How do I get bugs out my car?

You probably have a leak in your car and have sitting water underneath the carpet or in the trunk. You might check for service bulletins [sometimes called secret warranties] for your car and you may be entitled to a free fix. See if you can find a leak first, sometimes it entails replacing a seal or cleaning away debris. If you have had standing water under your carpet you may want to replace the padding under the carpet. If you need to replace the carpet you can find molded replacement carpet for around $125. I really doubt your Cheetos or that one spill as much to do with it.
