Spinosad appears to be a hazard to bees only at the time
of application and for 3 hours afterwards:

Example:
The Entrust Product Label says: http://www.cdms.net/ldat/ld62B023.pdf  

"This product is toxic to bee exposed to treatment and for 3 hours 
following treatment. Do not apply this pesticide to blooming, 
pollen shedding, or nectar producing parts of plants if bees 
may forage upon the plants during this time period."

The label also says:

"Entrust does not have a significant impact on certain parasitic 
insects or the natural predaceous arthropod complex in 
treated crops, including big-eyed bugs, ladybird beetles, 
Stethorus, flower bugs, lacewings,minute pirate bugs, damsel bugs,
assassin bugs, predatory mites or spiders.  The feeding activities 
of these beneficials will aid in natural control of other insects and 
reduce the liklihood of secondary pest outbreaks."
