Whenever we returned to the beach house after being gone for several days we would find a handful of mostly dead (in “The Princess Bride” sense) roaches scattered about. Where were they coming from? I caulked or foamed every crack I could find. Fortunately, my ever-loving wife, “Rochelle” (not her real name) was patient and cut me some slack because she knew I was really trying. (Not to be confused with the phrase, “He can be really trying,” which means something else entirely. I’m pretty sure I heard Rochie correctly but now I’m starting wonder if I was listening carefully.)
Plumbers and electricians like to drill holes. Lots of holes. The licensing test for plumbers has two questions:
- Can you glue PVC pipe?
- Can you drill a hole?
If yes, here is your license.
For electricians the questions are different:
- Can you strip Romex cable?
- Can you drill a hole?
Here’s your license.
Notice there isn’t a third question: Can you seal the hole? So although they are both good at drilling holes, the answer to that one is typically, “Not so much.”

In the pantry I found a dryer duct going into the floor that had enough space around it for a squirrel to get through along with a year’s supply of nuts so I foamed around that baby to slow down the varmint traffic. But still the roaches came.
I foamed the holes around the water pipes in the sink cabinets in the kitchen and all of the bathrooms. Still they came.
In the attic, I foamed the wiring holes that go into the tops of the walls. I caulked around the outside doors. It didn’t slow them down.
I pulled out the kitchen stove and foamed the openings in the floor underneath the stove. Same for the refrigerator. I squirted little puddles of roach bait poison in corners and by the doors. They are supposed to take the poison back to the nest so that the whole colony is wiped out. Maybe the roaches can’t read the instructions or they purposely flaunt them but that didn’t work either.

Then one day my ever-loving wife said she saw a roach on the countertop that scooted off and disappeared under the edge of the countertop. I looked up under there but couldn’t see where it had gone so I took out the top drawer to get a better look. (The drawer slides on each side have a little plastic lever that releases the drawer.) Nothing obvious so I figured it must have gone down behind the other drawers so I took them out too. Eureka! The answer was blindingly obvious.
The electrician had drilled a hole in the base of the cabinet to run a wire for the outlets. Oh, and I’m sure he sealed the hole. NOT! I was staring at a roach superhighway. The whole roach contingent could have crawled out of there side by side in parade formation. It was now clear that the little black dots in the drawers were roach rest areas when they needed to take a break from the highway.

Not only was there a hole in the bottom of the cabinet but there was another hole in the subfloor below it. Taking advantage of a more-or-less direct line to the roach hoard, I shot some poison down both holes.

Then I foamed the subfloor hole by sticking the Great Stuff gun down the cabinet hole. Did I mention it was a large hole? Then I foamed the hole in the cabinet bottom and replaced the drawers.
Result? No more roaches.
Sometimes I like to imagine the puzzled look on their stupid little faces when the survivors, if any, bump into all of that foam. What the …? It warms the cockles of my heart, if I have any, which I doubt because I tried to pay attention in school and I have no recollection of any mention of “cockles” when we were learning about hearts.
