French cookie 3x3 grow.

At end of week 8 of flowering. Yhe thrips population has exploded,i checked what type of thrips they are. It turns out they are onion thrips, . The predators dont work sp well on this type i have now found out. It explaines the population increase after adding the predators,im going to have to just get these through there last few weeks,and hope it does not effect production badly. Then disinfect the tent and euquiment. Any ideas on slowing them down ? I cant really spray the flowers with anything.
