We have a very strong smell of ramps in our house. We have checked under house in the crawl space and there is nothing growing under the house. Was wondering if the smell could be coming from under the front porch of the house, no access from the crawl space, or from where could the smell be from? The smell is starting to get in the fabrics in the living room, so what can we do?

Not to be disrespectful, but it would help to know what you mean by "ramps?" I have never heard that term used before concerning something that smelled.

Ramps smell like wild onions.

If it is a plant them it could be growing under the porch. If you have access to the porch spray it with a weed killer like round up and then sprinkle a good dose of granular caseron. Be sure you do not want ANYTHING to grow there again for a while. We did this in a weed ridden bed and had to wait two years for anything to grow there again...
