When tiny insects emerge from a bouquet composed of summer bulb flowers, this does no harm to the flowers but it’s certainly not pleasant for you. These insects have emerged from eggs that were laid there earlier and will usually have disappeared within a couple of days. One way to deal with this problem is to spray the bouquet with a mixture of dishwashing detergent, water and a dash of methylated spirits; another way is to place the bouquet outside on your garden table until the insects have flown away.
