According to the Alpine Roach Gel Bait product label "Apply gel in a 3 - 6 mm diameter spot (0.25 - 0.50 g). Approximately 10 spots per 100 ft2 are recommended for use under conditions with low to moderate infestation. For more severe infestations, approximately 20 spots per 100 ft2 are recommended. Apply many spots in areas of roach traffic and suspected harborage. Numerous small application spots are preferable to fewer larger application spots." Each spot of bait should be the size of a small pea. Each tube of bait gel is weighs about 30 grams.
