Under the sink
Where the drain pipe meets the cabinet, roaches move in
In most Rhode Island houses the trouble starts at the hole cut around the pipe in the back of the sink base.
The hole around the drain pipe
Open the cabinet under your kitchen sink, empty it, and look at the back wall with a flashlight. Whoever set that drain cut a hole bigger than the pipe, and in most houses nobody ever filled the gap. That ring of open space runs straight into the wall cavity, where warm pipes, dark framing and a little moisture are everything a roach needs. Johnston has plenty of these kitchens, from older capes and two-families to ranches that were remodeled one cabinet at a time.
Check the same spot behind the dishwasher, around the washing machine hookups, and where a supply line comes up through the floor of a bathroom vanity. Droppings that look like ground pepper or coffee grounds along the back corner of the cabinet are worth noting. So is a stale, oily smell when you open the doors.
If you find any of this, call Integrity Pest Control in Johnston at (401) 467-3344 and describe what you saw and where. The family sets up an inspection, and the sink base is a good place to point them to first.

Why they hide where the water is
A roach can go a good while without food, but not long without water. That is why the kitchen sink, the dishwasher line, the bathroom vanity and the cellar floor drain are where you find them, long before one ever crosses the counter in daylight.
A slow drip under a trap, a cold water pipe that sweats all August, a damp sponge left in the cabinet, or a pet bowl filled at night can each be enough. Rhode Island summers are humid, and a fieldstone cellar holds that moisture well into the fall. When the first cold nights arrive, insects look for warmth, and a heated kitchen with a wet cabinet is the obvious answer.
Cardboard is the other draw. Boxes stacked beside the water heater or paper grocery bags stored under the sink give them cover and a place to lay eggs. Moving cardboard into plastic bins, wiping the cabinet floor dry and fixing a slow drip are things any homeowner can do before the inspection, and they help whatever comes next.
Why one visit is rarely the whole story
Ask anyone in the trade and they will tell you roach work usually takes more than one visit. Eggs travel in small cases that hatch on their own schedule, so the young turn up days or weeks after the adults were dealt with. A kitchen that looks quiet after the first pass can have new ones working their way out of the wall a few weeks later.
That makes a follow-up visit a normal part of roach control, not a sign that something went wrong. The useful habit between visits is to keep notes: which cabinet, which night, roughly how many. Write it down and tell the family when you call back.
Seal what you can in the meantime. A bead of caulk or a stuffed collar around the drain pipe, a door sweep on the cellar bulkhead and a tight lid on the trash all cut down the places to hide. Integrity Pest Control has answered the phone in Johnston at (401) 467-3344 for over 30 years, and a second call to say you saw one on Thursday night is a perfectly normal thing to make.
