So use a tiny pea sized amount every 12-18 inches and put them on tiny pieces of paper unless you have a deep crevice to put it in but if you use strips you’re wasting it, but it is good for areas that are vertical, but better to fill any cracks w/caulking anyways , also if you want a paste the igr products are really what you want, OR ortho Orthene fire ant killer which you can use as the powder or mix w/water and use as a spray and spray in cracks and then it’s invisible.
