Q: I have bed bugs and everything I read says to seal all cracks in the room before using insecticide. The wood tile floor (Parquet?) has little cracks all round them. It’s very old and unfinished but I just want to seal it, not bothered by color or a bit rough or stains, etc. Ideally a one coat brush/roller job. Do you know of a sealer/treatment that will seal the surface and fill/bridge up to 1/16″ cracks?
A: Any coating you choose, whether it is solvent based, water borne or de-waxed shellac won’t necessarily bridge the gap but will flow into the cracks. There are safe treatments you can use for bug infestations such as Diatomaceous earth / clay. This very fine, talc like powder can be spread about and is harmless to people and pets if ingested. It should not be breathed in though.
