Roaches-Anyway to stop? (by Josh [CA]) Posted on: Jan 15, 2019 2:40 AM

Have a roach problem, and it got to the point that the roaches got into the dishwasher and possibly short circuited it so I need a new dishwasher.

I hired a professional exterminator, but its a losing battle because this is for a condo that shares a wall with a neighboring condo. Unless the adjacent unit also deals with their roach problem, the roaches are just going to move from my unit to adjacent unit and return when its safe.

Is there anything I can do that will make less likely that the roaches will want to return to dishwasher? I'm replacing it with a new one, and I was wondering if putting boric acid or diatomaceous earth underneath the new dishwasher would do that?

Which one would be better for this situation, boric acid or diatomaceous earth?

Roaches-Anyway to stop? (by Richard [MI]) Posted on: Jan 15, 2019 4:49 AM

Combat or that paste stuff.

Also, the key term in your post (they will return when it's safe) is your answer.

Never let it be safe for them to return! A constant protection is the way to go.

Roaches-Anyway to stop? (by GKARL [PA]) Posted on: Jan 15, 2019 5:01 AM

Try boric acid. That stuff works wonders and is low cost. Just spread it where there's evidence of them. They'll get it on their bodies and spread it to the nest poisoning them all including the unit next door. Some folks mix it with sugar. I found using it straight to be very effective.

Roaches-Anyway to stop? (by plenty [MO]) Posted on: Jan 15, 2019 5:17 AM

I would contact the condo association for help and or put letters on neighbor's door can where will they run?

Roaches-Anyway to stop? (by fred [CA]) Posted on: Jan 15, 2019 5:57 AM

Yes, boric acid is your answer. Available at 99 store.

Roaches-Anyway to stop? (by Doogie [KS]) Posted on: Jan 15, 2019 6:48 AM

My biggest headache to them has been 2 fold. Spread boric acid under all appliances and in cracks. This gets on them when they walk through it. They groom and ingest it. Their stomach cannot handle it and boom.

The other product is the Combat gel. It's like crack to them. They can't leave it alone, but can't live with it either. This one is better because they don't die right away. They will take it back to the nest and then die. Once the little cannibals go after the dead one, they die too. It's supposed to go about 7 cycles before losing effectiveness.

Between these 2 methods, I've gotten rid of pretty bad infestations. Having another unit that shared a wall makes it a lot worse. Have to keep a constant supply of these products spread around. The cleaner you keep the unit itself, the better it helps as well. Wipe down their trails, wipe out the sinks and tub after using it (no water supply). They don't like clean for sure!

Order invict gel online. Will take care of your problem.

Roaches-Anyway to stop? (by Robin [WI]) Posted on: Jan 15, 2019 7:49 AM

We also use Gentrol (from It releases a hormone that disrupts the reproductive cycle. This is the third prong of attack. With really bad infestations, we put one under each sink, behind the stove, behind the refrigerator, and replace every 3 months. In certain homes, we just do it as a preventive measure. Cockroaches can do a surprising amount of damage!

Roaches-Anyway to stop? (by WMH [NC]) Posted on: Jan 15, 2019 7:53 AM

DE doesn't work if it gets damp, so not a good answer in a kitchen.

But those large bug bait traps work wonders. I used to use a pro because we have water bugs/palmetto bugs/huge roaches (on the water, tree goes through deck, no escaping them) but they were still here scurrying about. Since I fired the pro and switched to those huge bait traps replaced regularly, if I do see a bug it's dead or dying. I've been using them for a few years now and it's amazing.

Boric and DE clump when wet, I use a kitchen sifter to solve that problem, only takes a whoosh out of a dish soap bottle to get under appliances, just blast it out everywhere often.

Roaches-Anyway to stop? (by Robert,OntarioCanada [ON]) Posted on: Jan 15, 2019 11:32 AM

First eliminate the means roaches can travel between units by chalking the cracks in the baseboards and kitchen cupboards along with installing insulation foam where ever pipes, wiring enter walls or floor. Roaches need a home to thrive so by eliminating homes that is a first step to taking them out. Next put bleach in the defrost pan of the fridge. Without a water source everything dies in 7 days. Next make sure there is food supply by thoroughly cleaning behind fridge, stove. Sticky traps around the perimeter of the room and other areas traps out some of the roaches. Had a roach will a trap with eggs. Max force or Combat gel once the food supply is eliminated the roaches will feed on. Three elements for survival are food, water and warm place to live and breed. --76.64.xx.xx

To be honest, boric acid works so well that I almost want them to come back so I can kill them all over again. I didn't get enough satisfaction from the last time because I didn't feel like I didn't extract enough payback for their previous infestations. Boric acid really messes them up and drives some of them crazy.

I just put some down in one of the units last week where a tenant saw one grown roach. I consider boric acid a nuclear option and I went all in immediately. I deployed Gentrol as well. You have to overwhelm them.

Roaches-Anyway to stop? (by Lilith [CA]) Posted on: Jan 15, 2019 1:27 PM

If Boric and DE clump when wet, how would a kitchen sifter solve that?

And, if the boric or DE is underneath the dishwasher and the new dishwasher isn't leaking, shouldn't that spot be dry so ineffectiveness when damp shouldn't be an issue?


Roaches-Anyway to stop? (by RR78 [VA]) Posted on: Jan 15, 2019 2:42 PM

For what its worth.

DE is now part of our painting jobs.

We remove outlet and switch covers anyway. So use one of those little puff dusters to shoot a little into every electrical box.

Main reason has been for preventive maintenance on bedbugs.

Most plumbing water lines under sinks are sealed. But if not it also goes in there.

Roaches-Anyway to stop? (by Rick [IN]) Posted on: Jan 15, 2019 5:01 PM

Spray low, bait high.

Roaches-Anyway to stop? (by BRAD 20,000 [IN]) Posted on: Jan 15, 2019 10:01 PM


On a sfh we do an exterior perimeter spray 3’ up and 3’ out from the foundation.

Treat the crawlspace.

They live behind panelling. Panelling makes elimination almost impossible.

DE should be dusted lightly. If thick the critters just walk over it without the desried effect.

Your place might habe them because the neighbors DID treat. I watched my roaches cross the driveway and enter the neighbor’s house while my bug man was treating my rental.

I LOVE Combat Gel but it dries in a day or two and is worthless. So put out fresh small strings every day.

The Gentrol makes them sterile. Helps.


Roaches-Anyway to stop? (by Ray-N-Pa [PA]) Posted on: Jan 18, 2019 5:05 AM

As gross as this might sound, after you poison the roaches, don't sweep them up right away. The living roaches will carry them back to where they are nesting and will eat their own dead.

In doing so they will end up also getting killed.

As an added benefit, they will crackle if you step on them
