Laying on the ground in the rain at night watching critters move about (two steppers, horned beatles..) became routine. Laying in my bunk on my beautiful yacht watching a palmetto bug scurry up the wall freaks me out! I am doing well on the targeted individual strikes but how do I get back to their base camp for an air strike?
+1 on the glue strips. Had a cucaracha problem on a yacht, and tried the bombs, sprays and "hotels". None worked for long. I learned that cockroaches carry hundreds of eggs on their bodies, and they hatch after mommy is dead. Using glue strips, I could see that there would be a "Halo" of just hatched Junior cockroaches around the late mother stuck in the glue. That "fixed" them!
In our 1st apartment we had a neighbor who raised roaches (northern palmetto bugs) as pets. We bombed our apartment, aired it out for 8 hours, cleaned every dish, glass, pot and pan, then ordered a pizza. As we took our first bite the roaches came back from their vacation at the dirty apartment next door. They sell glue strips that attach to glass for flies (don't ask). I could see taping them around dock lines like rat cones for palmetto bugs. The electric fly swatter-zappers give great satisfaction for smaller populaions.
I had some sort of cockroach bug problem this summer kind a look like a lightning bug without the flicker light. Anyway I had success with borax from the hardware store and confectioners sugar from the grocery store. make a paste out of both roll them together in a ball place them on tinfoil and hide them in all kinds of areas in the boat ; behind panels , in the bilge , under bunks , behind drawers etc. Set the Bates on little pieces of tinfoil they are completely odorless and can stay there forever. My bugs disappeared almost immediately in just a couple of days it was amazing.
Bugasalt, love it but too surgical. I have been reducing the fleet of bugs one at a time with no end in site. Thinking of running the boat to Maine in January and let the 20 degree temps get rid of them.
Get a pro. We ve had a few episodes over the years when critters hitched a ride in the few boxes we let aboard and a single visit from an exterminator solved the issue every time.
Yes that is probably the solution. Palmetto bugs and boats may be new territory for Maryland exterminator companies.
emailed a local pest control company this morning. They scheduled a tech to swing by between 1:00 and 3:00 today. I waited until 3:45 changing my Racors. No show. To add insult to injury one very healthy P bug walked by on the bulkhead while I was knee deep in diesel fuel. He stopped briefly and we made eye contact.
Buy this stuff, mix it up in a spray bottle and spray all door openings (floor), all around the edges where the floors meet the walls, etc. https://www.domyown.com/cyzmic-cs-controlled-release-insecticide-p-1420.html
The local pest control company visited the boat and did exactly what you describe . Two days later I went aboard and found dead Palmetto bugs sprinkled all around the interior. Hopefully that is the end of the critter issue.
