Bug Bombs for Indoors

[MuscleGirl'sHobby]

I grow my Orchids in a room in my house, which kind of gets used as and office/study area during the day. It's that time of the year when it get's colder and wet out, and all the buggies go crawling for shelter. Spiders are invading faster than I can swat, as well as some ants and little fliers too. In the past we've used those Raid Bug Bombs that you set and then leave the house for a few hours... but that was before all the 'Chids moved in.
Is there any harm done to Orchids using one of these types of pest treatment? I kind of guessed that there won't be a problem, but wanted to make sure before I do it!

Thanks!
