Getting Tough on Ants & Roaches

Get Rid of Ants and Roaches: One simple thing is keeping our boat pest-free despite being in southern Florida.

We try hard not to have ants and roaches on the boat. But this summer we are living on the northern edge of the Everglades. Ants and roaches are a fact of life around here.

Talking to people on the few other boats here in the yard, I think ours is the only one without an infestation of ants or roaches.

From our conversations, I think there’s only one thing that I’m doing differently. So I have to assume that’s what’s making the difference.

Every time we start a new trash bag, we spray a squirt of ant and roach killer into it before we put anything into it. Ditto for the bag lining the trash can in the head, and the recycled bags and jars that I use for garbage (food scraps) in the galley.

I can’t just spray around the floor or really anywhere on the boat, as we have a small (7 pound) dog. Paz is the licking-est dog I’ve ever encountered, but by spraying inside the bag when it’s empty, it’s nowhere that she can get into.

NOTE: when we first got the boat out of storage after just two months away – with plenty of ant and roach traps set out and no food having been on the boat while we were gone – we did have some ants and even a couple of roaches aboard. Within just a couple of days, there were none.

  1. Which spray do you use? Have you found some more effective than others?

    • I just buy whatever seems to be the “extra strong” at the grocery store. Since it’s usually not the same store as I bought it from the last time, it’s never the same. In general, I like Raid or Hot Shot but anything seems to work.

  2. When we were in a marina in Bali, all of our neighbors had an ant and roach problem. We started spraying the ropes with the same spray we used in the rubbish bins. It must have helped as we were the only ones in the area who were ant/roach free.

  3. If you have concerns about toxic chemicals I would & have used successfully cayenne pepper for ants. I don’t know if it is effective on roaches or not.

    • I don’t like to use toxic chemicals — I prefer things like the cloves and cayenne — but sometimes I’ve found that the sprays are the only things effective in a particular location.

    Is there a reason that something like Roach Pruf won’t work on a boat?

    • Roach Pruf is basically boric acid and works well, but you can’t use it anywhere that kids or pets could get to it. Boric acid isn’t all that toxic to humans and dogs/cats except for kids and small animals small size. We used a Mexican version of Roach Pruf on our first boat until we got Paz — but at 7 pounds, and the lickingest dog you’ve ever seen, we don’t want to risk having it anywhere that she might decide to lick. I could sprinkle a bit in trash bags, but the spray is easier.

        Thanks Carolyn:

        I can still put it inside places my cat cannot go like behind electrical plates and under trim. I have always used it on land because I am sensitive to the poisons, I had just wondered if it worked, I am currently a live aboard in Florida, looking to set sail next year.

  5. Diatomaceous earth. It’s a fine powder that is used for a wide variety of things. We buy it at the hardware store, where they sell it both as an insect killer and as filter material for pools. Farmers mix it in with the feed that they give their livestock to kill bugs. It is also one of the few insect killers that can be put on crops and still be considered 100% organic. So, not a poison, and not harmful in moderate amounts to any non-insect.
    But it kills any exo-skeletal insect (of which ants and roaches are just two examples). It kills them by mechanical means, rather than by chemical means. It gets into the crevices in their exoskeletons and basically grinds them to death. (Gruesome, eh?)
    We had a serious ant problem in our home that we were not able to control until we discovered diatomaceous earth. Sprinkled it outside around the home, inside in corners, and around cabinets. Ant problem completely solved.

  6. I worked on a merchant ship with a serious infestation, even fumigating the whole ship (everybody ashore!) didn’t work. I found the best by far are roach motels – ‘they can check in, but they can’t check out’. They are cardboard flatpacks that fold out as little triangular houses with bait and a sticky floor. After a few weeks the infestation had gone. Best to leave a couple of them out.

  7. We don’t have ants and roaches, thank God, but we do have a serious fruit fly infestation on our boat. I’ve tried the wine traps with different combinations of liquids and a drop of dishsoap that you read about on the Internet, but none seem very effective. Any advice, friends?

  8. excellent tip……

  9. Thank you for this tip!

  10. Great ideas. My daughter had what I called psycho ants in Key West. They would make you psycho.
