It is unlikely to do you much good, Chris. It is highly unlikely that your infestation is large enough to feed that many Cryptos even for a short time. As a result, the vast majority of them would wind up spreading all over your home instead of remaining on or by your plants. (In addition, these beetles are known for being wanderers.) The result would be a lot of dead beetles in short order. Not exactly a wise expenditure of funds, IMO.
Depending on what your winter temps are like, if your chids are currently indoors until warmer weather arrives spraying with 90% rubbing alcohol does seem to do a number on the mealies though repeated application would likely be necessary. There are also systemics which you can use.
Once temps are warm enough for the chids to stay outdoors, you could summer your orchids outside and let the predators in your area wage the battle for you.
