I have a weird smell in my house that began when it got hot in may I have since had an electrician, plumber and air conditioning person here to see if they can find the cause with no luck it seems more promident when its hot and sunny and leaves a bad taste in my mouth ant suggestions thanks

Try to explain it better here and try to say where you smell it most, what room or rooms.

Usually a plumber can locate dead animals. That's the first guess. But they can be in walls and ceilings and chimneys and crawl spaces. Try an exterminator, but you may not get one to look for free.
