You should place Advion Cockroach Gel Bait indoors and outdoors as a crack and crevice treatment. We also recommend that you use an IGR (insect growth regulator) such as Gentrol Point Source Stations, for even more complete control of all life stages of cockroaches. This will help prevent the infestation from getting larger while you are eliminating it. Advion Cockroach Gel Bait Application Instructions For heavy infestations of cockroaches, apply 3 to 5 spots of ADVION Cockroach Gel Bait per 10 linear feet. For light to moderate infestations of cockroaches, apply 1-3 spots of ADVION cockroach gel bait per 10 linear feet. Each spot of ADVION gel bait should equal about 0.5 grams (approx. 1/4” diameter). For all levels of cockroach infestations, when a bead of ADVION Cockroach Gel Bait is used, apply a small thin bead that is less than 1/8” wide and approximately 2 inches long. Each 30 g tube yields approximately 60 bait placements. Each box of 4 x 30 g tubes yields approximately 240 placements. See our Indoor Roach Control Guide for more examples of indoor placement.
