I didn't use (edit: MY Lavender-alcohol spray) around Cookie's room at all.just the carpet powder with Lavender.
I asked the exterminator not to spray in the reptile room because I (will) have diatomaceous earth down. He said he still has to spray in there but putting a towel over his tank will be fine. He said they use a non-residual, so after 10 minutes it won't be in the air at all. "They are all natural and made out of plants." And instructed me not to use anything else other what they are using or their warranty will not be in effect.
