A.If the roaches you saw in your kitchen and the roaches you saw in the garages are different color/sizes they are most likely two different types of roaches. Fortunately you can use the same method of treatment for both types of roaches. The larger roaches are wood roaches and do not nest indoors. The few times you will see them indoors would be if they were foraging around for food. However the small brown roaches in the kitchen are most likely german roaches. German roaches nest indoors and can multiply in large numbers if the infestation gets out of hand. We would recommend Maxforce FC Magnum. This will help you knock down any roach problems you have. This bait can be applied in areas unreachable by your niece such as in elevated areas like the counter or near the dishwasher and refrigerator. German roaches are likely going to nest near a heat/water source so applying the gels underneath the sink, along the water pipes would also be an ideal place for bait placement.
