Good Questions: Cockroaches In The Dishwasher?

10-11-cockroach.jpgHello AT,

Terrifying question: I have cockroaches living in the door of my dishwasher. It's an 1896 tenement, so I accept them as neighbors, but is there any way to get and them out of my diswasher? I would send a photo, but it's just too upsetting.

Thank for any help that you can give, Amy

Dear Amy,

This is mindboggling, especially since we know you just renovated and that is a brand spanking new dishwasher.

The only recourse seems to be a good exterminator. Pest Away has a great rating. We would give them a call.

We would also pull out your dishwasher (if you can) and take a look at what it is like back there. If there are any holes or any moisture, we'd fill the holes and dry the moisture immediately. You might have a leaky hose.

Anyone else!?!?

I agree - it is a frightening thing to open the dishwasher and see cockroaches scurrying about. Ewwwww! I suggest running the dishwasher a couple of times (using scrubbing action), with nothing inside. Also, rinse off dishes compeltely before putting them in the d/w. may want to ask your super to take the door apart if worse comes to worst. Good luck!

Sorry!

If you are a renter, then consult your city's "Landlord-Tenent Ordinance." Under this type of legal document, a landlord is required by law to insure proper maintenance of the building and each properties respective appliances, etc. There usually is a clause that also mandates that certain maintenance fees---eg., exterminating not due to tenent's fault--- is the responsibility of the landlord. If the landord does not pay for it, the ordinance allows the tenent to deduct it from her/ his rent payment. At least that's how it works here in Chicago. Bottom line, if you're a renter, contact your landlord immediately. If you're a homeowner, then consult your building's owner association to determine if other owners are bothered by the same cockroach probelm. If it's determined another owner is lax in cleaning and is responsible for the investation of bugs, then your building's association can force this lax owner to pay for the exterminating and other related costs (there should be a clause in your owner's association by-laws that mandates this). Good Luck!

I had a problem with them in the drain of my bathroom sink. I've used Boric Acid with success, both there and the large gaps between my floor and floor boards. You could try running the dishwasher with boric acid. It's really cheap.

roaches love electronics and appliances. the heat, teensy holes, etc. especially if it's close to moisture. i've had roaches in every dishwasher i've had in new york. if you're prone to them, dishwashers just make way too good a habitat.

posted by the opoponax on 2006-10-11 14:23:47

eeek-- this is truly horrible -- I have a dishwasher and I've never seen a cockroach in it but I'm going to put boric acid all over the floor around and under it immediately. I can't imagine anything more horrible that washing your dishes only to get cockroach marks all over them.

posted by Diana on 2006-10-11 14:28:16

Age of your buidling is no reason to accept them! Trick is to fill all cracks, gaps etc., clean thoroughly (they leave a smell that tells other cockroaches it's a good place to hang) then use Combat. Boric acid also works, but is not taken back into the walls to kill even more roaches.

I had some dead roaches stuck inside my old microwave, right in front of the clock/digital readout. Even though it stll worked, I finally got rid of it because I couldn't stand the sight anymore.

As far as your dishwasher, you will probably need to do a lot of spraying (of toxic stuff -- yuck!) or get a pro. If it's an expensive dishwasher, it's definitely worth doing.

posted by Frank on 2006-10-11 14:36:46

I believe boric acid is carried back and they die from chemical burns. I'd put some of that in the door, and then, after not using for a while, would run the dishwasher many times to cleanse.

I would also call an exterminator, though I am anti-pesticide except when necessary.

This is my nightmare (worse than mice!)
Hope you solve this problem.

I was told this by the exterminator people who came to my apartment to fumigate: cockroaches NEED water - they can go about 5-6 months without food but will not make it past 30 days without water. That's why they hang out in the kitchen and bathroom, where it's usually damp and where water is plentiful.

posted by Brown Boy Girl on 2006-10-11 14:45:56

I had this exact problem in my last apartment (ground floor). I ended up taking the dishwasher door apart and I found an actual cockroach nest inside the electronics. I was this close to vomitting all over them. I had Raid on hand and killed them all on site (which doesn't mean more won't come). So then I plastered the inside of the door with boric acid, underneath the dishwasher with boric acid and they dissappeared for a while (5-6 months or so). Running the dishwasher won't do anything if there's a nest outside of the water's path.

posted by Rusty on 2006-10-11 14:52:30

To get rid of them mix boric acid with Eagle Brand milk (it comes in a can). Dab this in the corners of cabinets and other places. Good luck!

posted by reggie on 2006-10-11 15:07:07

water neutralizes boric acid's effectiveness, so dumping it into the dishwasher is not going to work. get an exterminator.

I disagree with Frank, though, about boric acid not being taken back into the walls. Boric acid kills because roaches that walk through it ingest it in the act of grooming themselves. They die--usually in their hiding places--and then are eaten by other roaches, who ingest the boric acid that killed the first roach. it's the gift that keeps on giving.

posted by ocgrl on 2006-10-11 15:22:54

boric acid + silicone caulk (the bugs were getting in and/or hiding behind moulding) have really reduced the amount of roaches I see. That and keeping all my dishes done before bedtime, and drying out the sink afterwards. Oh! And glue traps! It's so gross (and yet satisfying) to see them all stuck on there.

move.

just pack and move.

admit defeat.

i'm serious – that's f*cking disgusting. we can't win.

Eeeuuu, sorry about that Amy. I don't know if this will help, but I recently made a rather fascinating discovery: last weekend, doing the laundry down in the basement laundry room, I saw a humongous waterbug, y'know the kind, ugh, big as an oversized thumb. It was going toward my shopping cart and I wanted to just rid of it. Other people in the laundry tried kicking it, swatting it, but no one had the nerve to kill it. All God's creatures,great and small, yeah yeah I know. But I grabbed the first thing I could find: an empty Clorox bottle. It still had a few drops of bleach left, and I just put shook them out onto the waterbug, who tried to shake it off, then ran about 3 inches and fell over dead on its back. Bleach, who knew?!

posted by Phyllis on 2006-10-11 15:45:53

Oooh, I once trapped a waterbug in my sink drain, but he kept trying to come back out. I clapped a piece of tupperware on top of the drain, weighted it with a plate (I DIDN'T KNOW HOW STRONG HE WAS!) and promptly boiled a few kettles of water and dumped them, with bleach, into the sink to drain him away. Good to know that worked!

posted by Laurel on 2006-10-11 15:50:46

Phyllis and Laurel--
a more non-toxic way to kill them is to spray them with a solution of dishsoap and water. I couldn't believe it would work, but it's replaced Raid in my house.

posted by ocgrl on 2006-10-11 16:00:42

I moved into a new apartment a month ago and found cockroaches in my dishwasher. While I'm sad for you, I appreciate that someone else is dealing with this nastiness.
The one thing I remembered (someone in a creative writing class with me wrote an entire short story about roaches in her apartment, lovely) is that they often lay eggs -or whatever they lay- in the rubber lining around the dishwasher, since it traps water and is all sealed up/hard to get to. Something to note...and tell your exterminator.

posted by Elizabeth on 2006-10-11 16:05:07

eek! sorry. I don't have that problem with my dishwasher, but will take preventative measure this weekend to make sure it doesn't happen.

Can't you run a cycle with something poisonous to them like Lysol?

It apparently works really well. It's so cheap, it's worth a shot.

i live in GA.... land of the palmetto (a.ka. GIANT cockroach)....we have also had to battle the german cockroach in my dishwasher as well.....
you MUST take care of them as soon as possible..they multiply really quickly....
they LOVE water and heat so do not run the dishwasher.... it will not get them out...i stopped using the dishwasher completely and we eventually got an exptermintor.....it took about 3 months and they are finally gone....
please don't listen to the people who told you to move out.. it's a BUG people! you NYers are spoiled up there!

I swear by roach motels. They won't solve this problem (I'd figure out how to get in there--maybe there is something you can unscrew to get at where they are?--and spray some black flag) but then put some roach motels around and replace them if when you see a roach.

You cannot begin to fathom the repulsiveness of my apartment-before-last. Rent stabilized with a total slumlord for a landlord, so I had to clean for two weeks before I could move in. When I peeled back the (foul smelling, half disintigrated moldy) carpet, the floor was teeming. I set off about three bombs but a few months later I was roach free. Whenever I did see a roach, I'd go out and buy new roach motels. They never did set up shop again.

You don't want to bomb in a place you live (and a bomb won't get into the crevices of the dishwasher) but what I am saying is that the most repulsive infestation *can* be turned back. Don't lose hope.

roaches also hate baking soda and bay leaves, so maybe if you put a bunch of bay leaves in the dishwasher it will keep them out.

posted by kh on 2006-10-12 09:54:58

I've done battle with them in NYC apartments fro years.

I contacted the New York Museum of Natural History years ago and they told me that the "German Cockroach" (pictured) dies from BORIC ACID, not by chemical burns or poisoning-- But rather by SUFFOCATION.

The roaches breath through air holes in their backs,the BORIC ACID clogs the breathing holes and they die.

VERY IMPORTANT!!! DO NOT clump the boric acid when you apply it. Lay it down as fine, loose and powdery as you can. Godd Luck! If they don't leave- replace the door.

posted by sanserif77 on 2006-10-12 10:28:30

P.S. A chemical insecticide with no less than a .025% amount of CYCLOPROPANECARBOXOLATE works the best. I've tested ALL the brands and the ones that worked well had this solution in them.

(Horrific but...After a while you actually start reading the labels)

posted by sanserif77 on 2006-10-12 10:37:59

Fumigate! I am kind of shocked that that so few people recommend this option.

I had a really bad infestation in my apartment when I first moved in. So I planted three Raid Max foggers and left for two days.

The foggers are water based and easy to clean up. I haven't had more than one or two individual sightings since, and that was about six years ago.

Also, the foggers can get into little cracks and crevices that we can't even see!

- move. just pack and move. admit defeat.i'm serious – that's f*cking disgusting. we can't win. -

My sentiments exactly.

posted by Thomas on 2006-10-12 12:01:09

I agree. Combat bait houses. If you have a really bad case, use Combat gel (not in your dishwasher), under your sink, behind your backsplash, any nook or cranny that you won't be able to see the gel ever after. Two weeks tops. I've moved a lot. Combat has always worked for me.

posted by elizabeth on 2006-10-12 13:36:02

It's me again.

Important! Roaches DO NOT eat food remains. But they are intensely attracted to the glue-binding in paper products and cardboard boxes. Remove ALL paper bags and boxes. Roaches also LOVE water. Dry all water in and around sinks, drains, tubs, toilets and inside the dish washer. Again GOOD LUCK! I sympathise with you.
If all fails. I agree with Thomas- Move! and DON'T PACK IN CARDBOARD BOXES OR YOU"LL JUST BRING THE ROACHES TO THE NEW APARTMENT.

posted by sanserif77 on 2006-10-12 14:34:19

eek! im sorry for you too. sound like the exterminator then natural way is best. I've been seeing a few- what i think are "baby roaches" in my apt. could that mean i have roaches? i'd rather have mice. ugh!

posted by d on 2006-10-13 13:17:24

Had this problem and solved it thusly...I put those black Combat bait/trap things inside the bottom of the dishwasher, underneath the bottom rack when I wasn't using it. Shortly thereafter the roachies ceased to bother me. I think I didn't use the dishwasher very much during this period so maybe that helped too.

I totally sympathize with the fear that grips you when you are about to open the dishwasher door...

The information gathered by sanserif77 has been
the best so far. I just moved into an apartment
where I expected to have these ceatures crawling around. After 3 weeks of battles, I can't say I've
won the war; yet. Cockoaches are very clever and
have been on/under the Earth since the age of dirt.
I do seem to have them under control - the ones I now see don't run, they stand still upon my approach. I did lots of checks on Google and the like for Control ideas. Before my dishes went inside the cabintes, I spread bay leaves on the shelves due to them [roaches] not liking the smell, I powdered my kitchen with boric acid, and I sprayed a garden-strength insecticide in both the kitchen and bathroom (among the other rooms). The chemical is Bifenthrin, which is good for both outdoors and indoors; to boot, it has no odor
(at least to us humans). The sinks are dry, all food is refigerated until ready to cook or eat,
and I run the vacuum each day.

Good luck with this.....

I moved into my apartment 4 months ago and the first week had problem. Baby roaches coming out of the cabinet cracks. i sprayed the entire thing with raid. That made them all come out, and then it got bad. I called my landlord immediatley and he had his exterminator come out and spray, for the next few days more emerged. I think it's a process when you spray, I heard they come out because if they pass the threshold they die. I didn't see a thing for 2 months after and then I started seeing baby roaches here and there. I called my landlord and the exterminator came out again. Now I am finding dead ones. Can this mean they are going away. I have a very intense phobia when it comes to these things. We have 3 more months left on our lease and we are out of here. I am worried about taking them with us. Should I be worried?

posted by stephanie on 2006-10-25 21:40:45

OMG, I have a dishwasher, but I don't use it, but it's right by the microwave which IS infested. Would it be okay to pour boric acid in the microwave itself? The nest is there, and I can't replace the microwave or get rid of it....

posted by Ami on 2006-11-12 00:57:03

Roaches are huge pests. Today one of them sat on my shirt when i was on the sofa i saw it on my sholdier. It then fled to my room where i sprayed it with 15 sprays of lysol bathroom cleaner, then it died. UGH

i have seen roaches in my microwave clock,how discusting and i have only had my microwave for a yr. i need a solution in getting them out ....

posted by fedup! on 2006-11-21 09:38:05

Eww. I am in such sympathy. I am planning to move as soon as I get a new job, I have roaches all over my place. Its awful. I am worried that I will move them in my electronics. How can I avoid that? Any ideas. I am planning to use brand new boxes and carry each package out as soon as its packed, with some boric acid in it, but I am worried about what to do for my computer, microwave, and television. Any ideas?

posted by Amy from IA on 2006-12-01 19:41:04

Wow! I can see my story in all these others. I am worried too about moving the cockroaches with me. Any ideas?

I originally found one in my sock in the middle of the night, while I was wearing it! Also they jump on the mattress at night. I hired an exterminator but the poisen made me ill. When I had him spray, I gathered my cats in their carrier and taking one overnight bag, went to a motel. A cockroach hid out in the carrier bec I heard it later that night eating the empty cat food cans in the garbage! I have heard them eating and it sounds like tiny starving mice. All the spraying slowed them down, but they are back again. It sounds like molding popping at night. I also had them in the bathroom sink drain and it sounded very large I put down clorox but it didn't deter them. Believe me it is hell. So that is why people say move.

I am trying to but do I have to leave everything?

Roaches are unpleasant but hey they're part of life in a city...Here in Australia we have much worse bugs to worry about
