When you get a house back that is cockroach infested, what do you do next? Call a pro exterminator ? Or do you have system in place to where you do your own pest control? What pesticides do you use? --71.207.xxx.x

Get an ozonator and run it overnight a few times. Kills bugs dead. Also people and plants, so be careful. --50.82.xxx.xxx

I had an infestation last year, hired an exterminator with a 6 month guarantee. Up to the last week of the 6 months the roaches were still there after repeat visits every 2 to 3 weeks. --131.239.xx.xxx

When you do a rehab sprinkle borax behind the walls where they walk,that will kill them before there is a lot of them and you wont even know you had them sometimes.I havent had a roach infestation in years but i called in a pro when i did.If you think roaches are a problem wait till you get bedbugs --74.77.xx.xx

1 ounce per gallon of water, I spray the entire house. The next morning, hundreds of dead roaches everywhere. Every 3 days, I repeat the spraying. I only do this in vacant houses though. --71.207.xxx.x

The diatomaceous earth works wonders. At least it did on the cockroach and flea infested house I got back once. But we were able to get the more potent stuff and spread it all over. So sorry. --75.89.xxx.xxx

I use Advion Roach Bait Gel, Nuvan pro strips when I can get them, plus a combination of Optimate and Pivot in a pump-sprayer, plus Gentrol Point Source to break their life cycle. --137.118.xx.xxx

If using diatomaceous earth, be sure to use FOOD GRADE, not stuff from a pool store. --73.40.xxx.xx

Place them under sinks and around food source. --99.103.xxx.xxx

How bout a match ? --24.183.xxx.xxx

And whewnevr I go there, wear a coverall suit & hat! LOL --68.229.xxx.xxx

Do the smart thing, hire a Licensed Bonded Pet Control Company and get a contract spelling out what they are going to do and the warranty! --47.155.xx.xxx

I have started doing 2 minute home inspections which hopefully will eliminate the real filthy applicants. In one of my cock roach infested houses, which after 1 week of spraying, is just beginning to show some results. This same tenant (who I had to evict twice) left me with another problem which I will make a separate post on. Imagine hot cooking oil (fried chicken grease) being dumped outside in the backyard in one 3x5 ft. spot for 3 years! --71.207.xxx.x

He also mixes Genetrol in the Orthene. --96.234.xxx.xx

Have any of you seen a OLD Exterminator? --99.103.xxx.xxx

Integrated pest control where the elements must be eliminated which are food, water along with warm to live. Thoroughly clean behind fridge, stove along throw out any food source. Make sure there is no water source where without water for seven days the roaches are history. Chalk all the cracks in baseboards, kitchen cabinets along with insulation foam where pipes enter walls or floors. A shop vac will get rid of the severe roach problem. Once the food, water source is eliminated then Max Force gel or Combat gel around the perimeters of rooms as roaches only travel around the perimeter. Sticky traps around the perimeter of rooms will catch some roaches. It take time as slowly the roaches will eat Max Force or Combat then slowly over a period of three weeks the population goes down. If there is food source then roaches will continue to survive. One dead roach is a food source up to 45 roaches as the gel will start to work. --68.69.xxx.xxx

I have done this many times, use gel bait on top of every corner of window trim, on the hinge side of door trim and kitchen cabinet doors, you will be sweeping them out. Boric acid may be clumped up, so I use a kitchen tool used for baking flour - put red tape on the handle so you never use it in the kitchen again, use a funnel to drain this finely ground powder into a bone dry shampoo bottle - you will then squirt this under all appliances - for a bigger effect stomp on the bottle - whoosh. --76.190.xxx.xxx

BTW - The last time I had to deal with these nasty German Cockroaches - part of the problem / source was the leaking fridge drip pan. Isssh !! --108.231.xxx.xxx

If they get ahead of you - I call in the pros --24.101.xxx.xxx

--71.207.xxx.x

Diatomaceous Earth and Boric Acid are effective as preventative measures, but once you have an infestation they would take too long to eliminate it. --68.84.xxx.xx

Before any treatment the elements must be eliminated first as without food, water and a place to live the roach population will go down. --68.69.xxx.xxx

I know what an infestation is - a few creepy crawleys around or a couple on their back under the fridge or in a drawer are not it. Those who have never seen it should hope they never do. Thank goodness it's been 17 years. My very worst was a unit in a building I purchased and I wasn't permitted in the unit prior to purchase. The people I purchased from had owned it for I believe 7 years. They had never ever been inside either. Exterminator to this day tells me it's the worst he's seen in his 40ish years in business. A match would have been easier. That was the beginning of the end of my ownership of my older, well used, units. --98.237.xxx.xx

We've had 2 that I can remember that were left like that, and one that was a foreclosure sale we bought. We put bait stations, used 3 different brands of gel, also bombs. It took a while but only one was so bad that we broke down & called an exterminator because it was a short turnaround. --216.126.xx.xxx

Oh my this reminds me of a family that brought in roaches to our house. We hired a pro who kept coming back until they were all gone. We used the time to Rennovate but we did not rent it for a year. We had to o make sure it was good. New tenant has been there since 2015 and she is emaculate. The pro is the way to go. --71.234.xxx.xxx

Saw one a while ago where a young lady was at the emergency room and the doctor pulled a rather large roach from her ear. A trip to the gas station to fill the gas can on the way home would have been completely appropriate ! --98.237.xxx.xx

Trying to figure out what the ozone machine does from the previous post? --174.209.xx.xx

Trying to figure out what the ozone machine does from the previous post? --174.209.xx.xx

As to the ozone machine - Ozone is toxic to cockroaches (and a lot of other bugs), but can be dangerous to humans and other animals. The machine uses techno-magic to make ozone (O3) gas from the oxygen (O2) in the air. The Ozone breaks down very quickly back into Oxygen. So, put the machine in the unit, make sure that there are no open windows/etc, then set the timer on the machine, then leave and let it run. come back a while after it's timer is done, maybe open up a window for a minute, and you are done. Because it can be used unsafely, I think some states may prohibit using it. --50.247.xx.xxx
