Roach help (by TM [IN]) Posted on: Oct 17, 2020 8:03 PM

Need some suggestions/help with this. I feel like I have thrown the kitchen sink at my roach issue and missing the target....

Background info: its an 8 unit building. tenant in #4 starts with the roach problem, doesn't tell me. Moves out in July. I start treating. My tenants below and beside are dead beats taking advantage of the state eviction ban. When the state lefts the ban, they move. I treated with the following:

-bleach in all drains, clean all food out of apts.

-maxforce and advion bait stations in kitchen and bathroom

did this for 2 weeks.... still see a few

-paid an exterminator to spray all the units. base trim, cabinets. Supposed to kill for 45 days...

-came back with boric acid with lure under the base board, behind cabinets, under the fridge, and holes in the wall (drain or water lines)

-used drione and delta dust in electrical outlet boxes. Placed a tab of advion on the backside of the face plate through out the apt.

Didn't see any evidence on my strips (duct tap with sugar) for two days. Started to move tenants in. 3 days in, "i see roaches" text...

Came back, placed invict taps in cabinets, under drawers, on face plates. Sprayed Gentrol in cracks...

week later, still seeing some. But not in the kitchen. In the bedrooms and living room. tenants are clean. No food or drink left out.

What I'm i missing? no water source in the bedroom or close by.

Kicker is, they left this building and went to the building to the south. Now i'm treating there too. Since the first contact about it, I sprayed Cy-kick around the perimeter of the building above recommended label rates.

Any suggestions? these are german roaches.

In my apartment buildings, once a roach problem starts, it's hard to get ahead and control the problems.

For example my tenants go to the "Mexican Market" where the groceries are put in Boxes and not disposable bags. These boxes were from shipments to the store and then left outside in an alley overnight, to be used the next day for customer carry out. But once left in the alley, roaches lay eggs in the cardboard box voids. The tenants take home the boxes and leave them inside where the roaches hatch by the hundreds and spread...

I had several families continue to shop at the Mexican Market and take home boxes with roach eggs. Finally I took a Clear Large Plastic Bag and sealed inside an empty box from a tenants return trip from shopping at the Mexican Market. Within a few days, dozens of tiny roach babies were seen inside through the plastic bag.

I called in a roach pest control company and then sued my tenant and the Mexican Market for the Roach problem. The market refused to pay 1 cent towards the issue so I sent reporters after them, it made the 10 PM news. The market then lost 30% of it's business....Talk about shooting oneself in the foot!

My tenants that kept on allowing the roach problem to continue, even with my pest control on contract, I had to evict them....and I did.

Wow. I have nothing to add, but I feel your pain!

Try different products. Vendetta was good for German roaches. The last unit that had roaches we used maxforce magnum and temprid fx --66.30.xx.xx

Integrated pest control is making conditions where roaches can not live. First chalking all the cracks in the baseboards, kitchen cupboards along with insulation foam where pipes enter walls or floors. Remember roaches need homes to live and breed. Next water source is essential to live. Putting bleach in the defrost pan of refrigerator eliminates water source. Nothing lives without water for seven days. Also the sinks need to emptied. Third food source make sure behind the fridge, stoves along all the garbage is taken out. Roaches always travel around the perimeter of room close to walls. In some cases sticky roach traps where once in they can never come out. Max Force gel or combat gel takes time to work where if there no food source then roaches will eat the dead roaches where one dead roach will take out up to 45 roaches. Look under kitchen cabinets and bathroom vanities to check for any leaks as this can be a water source.

Tough one.

Sprays will push them away from bait, making bait useless.

The gels will dry quickly making them useless.

So they scoot away to avoid the spray then come back when the spray has dispelled. The gel is now dry and leathery so they cannot eat it.

Dusting is good.

My suggestion is to look next door on each side. We just spent the summer battling roaches only to find the neighboring house had MILLIONS.

At one house I stood outside talking to the neighbor while my bugman sprayed inside. I watched an army of roaches leave MY house, cross 30 feet of grass and gravel driveway straight to HIS house, like they knew exactly where to go.

E sure to specify a PERIMETER SPRAY - 3 feet out into the yard and 3 feet up on the house AND treat the basement/crawl.

If the chemicals and the pro are not eliminating the critters you have a physical problem such as neighbors or trash.

The thing I have had the best luck with is Temprid FX spray. In the spray, I also mix Tekko Pro Insect Growth Regulator. I spray the baseboards around the entire unit. Don't forget to pull the fridge and stove out and treat behind. These are the 2 most common areas to hang out. On a multi-unit, you have to treat the whole building. Treating one unit only causes them to play musical units as you treat each unit. I also put Invict Gold Roach Bait Gel and Invict AB Insect Paste on high concentration areas. I alternate between the two on each treatment. As BRAD said, the gel will dry up and go useless, but it does help for a while. On a really bad infestation, this takes 2 - 3 treatments. I have had it work in 1 treatment.

On top of that, deep clean. Get rid of food crumbs, seal up packages of food and clean everything. Fix any leaks in plumbing (get rid of their water source) as well. The stove area will tend to be extra greasy, which they LOVE. Don't forget to clean the back of the stove as well. Grease pops from frying something, hits the wall and runs down the wall and back of the stove.

While the pros can get rid of the problem, I have unfortunately found the opposite to be true with a few of them. It felt like they sprayed something weak to give the bugs a headache, but not get rid of them totally. They would then come and spray again (with another fee of course). Rinse and repeat over and over.

to add to Brad's story, I used to own a building where they came up the sewer lines and in through the sinks from an infested building about 250 feet away.

Roach help (by Vee [OH]) Posted on: Oct 18, 2020 1:46 PM

I read up the bleach part, that is where the roach formulae stop working, like tear gas bleach forces them deeper into the walls at upward as they are heat seeking insects. vent out any bleach odors and use corn oil in the drains so they can not use the sewer as the highway to another unit, flood the trim strips with a -gentrol- type product which stops the female from setting eggs and allow that to off gas for 30 minutes before using gel on the tops of all trim strips which is where they go sightseeing as it is warmer at the top, they eat and get sick to die, you may have to retreat but when they smell the clorine the females that can will set over 200 eggs in 24 hrs.

This is the approach I have used to clear some pretty nasty infestations from some duplexes and SFH's. I'm talking the kind that when you open the front door you stand back and wait before walking through because it rains roaches for a few seconds. All products bought from

Delta dust in walls around switch/outlet boxes, under appliances, and any other opening that you can get your duster into. Sounds like you have already done this. If you can, pull the appliances away from the walls and dust in any openings on the back of the refrigerator or range. They love the warmth that these appliances put off and the water from the condensation of the refrigerator.

Defense-SC tank mixed with Gentrol IGR sprayed around all baseboards in property. If you think they are moving from building to building you should spray this as an exterior barrier as well.

Invict Gold gel on top door hinges of all interior and exterior doors. Also placed on kitchen and bathroom cabinet hinges. Pull cabinet drawers and place on the back part of the slide. Anywhere else you see signs of heavy infestation use this. If there are tenants in place and they have things hanging on the wall, pull those off and if there are roaches behind them, place some on the back of the picture or whatever it is. I have also ran beads of this on top of the door header trims when heavily infested.

Gentrol IGR disks placed under the kitchen sink and each bathroom vanity. I have put these on the back of refrigerators and on the inside of closets above the door as well.

Repeat gel and Defense-SC (without Gentrol mixed in) every two weeks until you aren't seeing them. From then on you should be able to control with the Gentrol IGR discs and occasional gel treatment.

When you think you've got them whipped, get a flushing agent of some sort (I use CB-80) and spray in any cracks in cabinets, under toe kick, etc. and if there are any there, some will run out.

When you have a really bad infestation it is all out war and you have to do everything you can to win.

Finally, cleanliness is a must. If you have tenants who aren't keeping their kitchens clean and their trash taken out you are fighting a losing battle.

Hope this helps. --70.178.x.xx
