(6 Pack) Johnsons Vet - 4 Fleas Room Fogger Spray 100ml

I was pleased that there was no unpleasant residue on surfaces after using these, and there was the odd dead fly/woodlouse around afterwards, however I'm not convinced of the full efficacy of the product as I looked through the glass doors into our lounge/dining room to watch the two I'd set off in there, and the spray did not last very long and did not appear to fill the room with a cloud of product which I'd expected to happen.

Doesn't kill the flea eggs.
