Does it work outside in the light? or only in places that are in the shade? since it's photo sensitive.

BEST ANSWER: Outdoor Application: Apply as a surface application (including Broadcast, Spot and Crack
& Crevice) at the rate of 4 ml. in one gallon of water (or sufficient volume of water to get
adequate coverage) to treat 1,000 square feet. Use up to 12 ml. per 1,000 square feet for
insect populations that are difficult to control or in conditions that make it difficult to get
control of target pests. Alternate mixing directions for power spraying are to use 18
to 56 ml. of concentrate per 50 gallons of water. Apply to surfaces where insects breed,
travel, rest, hide or harbor. Treat known and suspected breeding sites on, under and around
exterior surfaces of buildings, walls, window frames, around garbage cans, eaves, cracks
and crevices, porches, decks, gazebos, patios, carports, garages, stagnant water, moist/
shaded areas, fence lines, and other areas where target insects are active or may be hiding.
Since NyGuard´┐Ż IGR Concentrate is photo-stable, outdoor applications on soil surfaces will
provide residual IGR activity, depending upon soil type and weather conditions.

Good Growth Regulator
I mixed this with an insecticide and it worked great! And when I didn't know how to use it, I called and asked for help and they were patient and went through step by step on how to use this item.
