Product Overview

Maxforce Professional Roach Gel with Hydramethylnon kills roaches by ingestion and contact, and spreads from roach to roach to kill even the roaches you don't see. Maxforce Roach Gel has a slower kill than the Fipronil (Maxforce FC) formulation, but the delay allows the poison to spread more thoroughly through the roach population. Each box contains 4 x 30 gram tubes of bait.

We provide 1 Plunger PER ORDER to expel the bait from the tubes.  You can purchase extra plungers or you can purchase a bait gun for use with this product. We recommend using the Masterline Professional Bait Gun.

Very slim part of tip must be snipped off to open the tube.

How Maxforce Pro Roach Killer Bait Gel Works

New Maxforce Roach Killer Bait Gel is simply irresistible to roaches. When other baits won't attract aberrant-feeding roaches, Maxforce Roach Bait Gel will. In side-by-side comparisons, Maxforce Roach Bait Gel outperformed competing brands. With a proprietary formula developed by Bayer, the new gel attracts and kills both finicky and normal roaches — even when sanitation is poor and other food sources are available. Maxforce Roach Bait Gel provides long residual and fast control of even large roaches.

Maxforce's exclusive Domino Effect delayed killing action enables one contaminated roach to kill many others where they live and breed. A foraging roach will receive a lethal dose from a single feeding, but lives long enough to return to the harborage where its poisoned feces are consumed by other roaches. It's all possible with Hydramethylnon, the active ingredient in Maxforce Roach Gel. Hydramethylnon is a metabolic inhibitor (in a group of pesticides called trifluoromethyl aminohydrazones) with a unique delayed-action property to maximize control of ant and roach populations. This causes the target pest to have decreased energy, lethargy, and the inability to perform basic life-sustaining functions such as feeding and grooming. Symptoms are delayed, with death typically occurring within 24 to 72 hours.

About the Maxforce Domino Effect
Our control formula gives you superior long-term control of roaches compared to contact sprays. The active ingredient, Hydramethylnon, provides a unique mode of action that works through both ingestion and contact, knocking down roaches and ants that eat or simply touch the bait. Either way, one contaminated roach or ant kills many others where they live and breed. The Domino Effect achieves population control with this roach gel bait with hydramethylnon. Maxforce Pro Roach has a slower kill than the fipronil formulations (Maxforce FC), but it is found to spread more thoroughly through the roach population for a better secondary kill.

Target Pests

Roaches, including American, Brown-banded, German, Oriental, Smoky Brown

PESTS CONTROLLED: Cockroaches including German Roaches, Brown-Banded Roaches, American Roaches, Smokey-Brown Roaches, and Oriental Roaches

Target Uses

Maxforce FC Roach Bait Gel is labeled for both indoor and outdoor use, including commercial kitchens. Maxforce Roach Bait Gel has USDA authorization for use in federally inspected meat and poultry plants. What's more, you can use Maxforce Gel in residential food processing areas without covering food preparation surfaces during treatment. It's also fine to use in occupied rooms of hospitals, nursing homes and extended care facilities.

Maxforce Pro Roach Killer Bait Gel can be used for virtually any roach infestation, but it should not be used solely as a preventative measure. The slower-acting Hydramethylnon makes this bait ideal for low-level infestations or situations that may have remained stagnant for long periods of time. Be sure to eliminate competing food and water sources for best results when using baits.

ACTIVE INGREDIENT: Hydramethylnon 2.15%

Application Instructions

Apply Maxforce Pro Roach Killer Bait Gel as a spot or crack and crevice treatment indoors and outdoors. Application rate is dependent on level of infestation and species to be controlled. Bait can be applied as spots or as a bead in cracks and crevices. The lower application rate should be used for low to moderate infestations or re-treatments and the higher rate for more severe infestations or where the population occurs in inaccessible areas, such as in walls. Gel placements should be at or near harborages or aggregation areas, such as corners, areas of movement or cracks and crevices. Numerous smaller placements will provide faster control than fewer larger spots, especially for German cockroach control.

Pest population reduction will be apparent within a week or less.

Unscrew the black cap (or break off the tip) and replace with included open tip before use. After use, replace the black cap before storage.

Maxforce Roach Killer Bait Gel may be placed into refillable bait stations designed for interior or exterior/perimeter use; when placing bait in the station, do not exceed the capacity of the station’s reservoir. Close bait station securely after application. Inspect placements and reapply as needed.

***Always read the product label completely before use.

Each box of 4 x 30 g tubes yields approximately 120 bait placements.

Standard Application Rates:

*1-2 spots about the size of the gel syringe cap or 1.5” – 3” bead: Moderate infestations or retreats for German or Brown-banded roaches

*2-4 spots about the size of the gel syringe cap or 3” – 6” bead: Severe or heavy infestations for German or Brown-banded roaches

*Spot sizes ¼ - ½ g (actual size syringe cap): Large roaches such as American, Smokey-brown, or Oriental

For use in the following areas:

Indoors and outdoors in residential areas and the non-food/non-feed areas of institutional, warehousing and commercial establishments, including warehouses, restaurants, food processing plants, supermarkets, hospitals, nursing homes, motels, hotels, schools, laboratories, computer facilities, sewers, “aircraft”, buses, boats/ships, trains, pet shops, zoos; food/feed areas of food/feed handling establishments; USDA Federally Inspected meat, poultry, and shell egg grading plants


Following is a general room-by-room placement guide for Maxforce Roach Bait Stations (Exact placement should be based on a complete monitoring and inspection. See our Indoor Roach Control Guide for images.):

Kitchen Bait Station Placements

* Sink: Alongside pipe collar where drainpipe enters the wall
* Cupboards: Flush mounted against an upper corner
* Other appliances: Behind microwave, toaster, blender, coffee maker, etc.
* Floor placements: underneath dishwasher and/or oven

Kitchen Gel Placements
* Drawers: Alongside the interior of the door frame
* Cupboards: Underneath selected cupboards where frame meets wall
* Counter: Underneath counter where sink is located
* Fume Hood: Along the inside rear corner of hood (ensure no gel will drip onto stove top)

* Garage: Flush mounted to door frame where roaches can enter residence

Other Room Gel Placements
* Interior piping: Around all exposed interior pipe channels (such as hot water heater inlet)

Food/Feed Handling Establishments: Treatment is limited to crack and crevice treatment only. Place applicator tip 1/2 inch into cracks, crevices, holes and other small openings where roaches may be a problem. Apply small amounts of gel per spot. Do not apply bait to areas where food/feed, utensils or processing surfaces may become contaminated. Do not apply bait to areas that are routinely washed such as cracks and crevices in tops of tables, food/feed preparation and prepared food holding surfaces as bait may be removed by washing. Apply bait in small amounts between different elements of construction, between equipment and floors, openings leading into voids and hollow spaces in floors, walls, ceilings, equipment legs and bases, around plumbing pipes, doors and windows, behind and under refrigerators, cabinets, sinks, closets, stoves and other equipment where cockroaches hide. Inspect bait placements and reapply as necessary.


Place in areas adjacent to structures where roaches may rest or breed. Apply bait to potential points of insect entry, such as eaves, sills, and expansion joints. Apply bait in protected areas whenever possible. Environmental stresses such as direct sunlight and water will reduce the residual effectiveness. Priority treatment areas may be identified by visual inspection of such areas listed above or aided by trapping techniques or spot flushing.

Outdoor Gel Placements:
* Rain Gutters: Apply in seam between rain gutters and roof
* Attic and Soffit Vents: Between air vent holes
* Siding: Under siding/molding
* Exposed pipes: Around all exterior pipe collars or where pipe enters wall
* Also: In brick weep holes, in window cracks and crevices, around decks and stairs, around the intake vents of air conditioning units

Maxforce Pro Roach Killer Bait Gel Features

  • Domino Effect works through ingestion and contact in hard-to-reach and inaccessible areas.
  • Contains unique bait matrix.
  • Effective residual of up to 1 year or until bait is completely consumed.
  • Better secondary kill.
  • Ideal for sensitive environments.

Extra Tips

  • Inject Maxforce roach killer bait gel directly into small cracks, crevices and voids that harbor roaches.
  • Smaller, more frequent gel placements provide faster control than larger, less frequent placements.
  • Store Maxforce Gel in a moderate temperature range. The gel will start to liquefy at temperatures below -10 degrees or above 140 degrees Fahrenheit. When returned to moderate temperature, the gel will regain its normal consistency with no lost effectiveness.
  • Gel may stain textiles and some porous surfaces. Place gel directly into cracks and crevices or hard-to-see areas where a stain will not cause a problem.
  • Use within 2 years of purchase. Use a tube within 1 year of opening.
  • Apply bait away from air currents to prevent drying. Avoid placement on paper, cardboard, or other porous surfaces such as unsealed concrete.
  • Do not use sprays, heavy detergents or cleaners near baits as this can make baits less attractive to roaches.
  • Sanitation should always be the top priority when treating for roaches! See our article How to Get Rid of Roaches for more information.
  • Good programs rotate baits to avoid resistance. Change baits every few months or alternate with different bait (and different active ingredients) for best results.

    Results are amazing.

    By Terry on 09/05/2008

    I worked in a Nashville, TN restaurant as a manager for a few years (2000-2006). One of our locations was infested with roaches. After Termin----, etc etc would come in and spray, the roaches came out everywhere! Terrible for business, terrible on our health department reports. After 3 years I got so frustrated with this problem and so worried I might start bringing them home with me, I did some Internet research. I read about Maxforce Pro Roach Killer Bait Gel and asked the general manager if we could please try this. He said we were not allowed to do our own pest control (apply it ourselves) as a health department rule. So I talked to our pest control company and I can't remember their name or I would use it here, and they said yes they had heard of Maxforce and he would start using it in our restaurant. Within 2 months we couldn't find a roach if we tried. Two months may sound like a lot of time but considering the size of our restaurant and the huge infestation we had, that was a miracle. I am now out of the restaurant business and live on a farm in Texas 2008. I have no idea how, but after living here for over a year we now have roaches in our house! Even with all the restaurants I worked in that had roach problems I managed to never bring them home. It brings back nightmares. So I now am going to purchase this product to bait my farmhouse. I can't wait until the product arrives and I already know the results will be amazing.

    Great stuff!

    By Cg on 10/30/2008

    My daughter's boyfriend gave us a tube of the MaxForce Pro Roach Killer Gait Gel being that we had a problem with roaches. After using fogs and other roach bait nothing seemed to get rid of them all. Thanks to my daughter's boyfriend we used the MaxForce and saw some results a couple of days later when we saw that they had come out and had died on the floor. This is some great stuff you are selling. Please don't ever stop cause if I ever need you again I know where to come to order it. Thanks Again, Happy Customer In South Carolina

    It did kill some roaches.....

    By Craig on 06/12/2010

    Verified Purchase

    It did kill some roaches. But not all of them. Maybe I need to buy more.

    Expert ResponseExpert response:
    In a very bad infestation it is important to use a variety of products.  If the infestation is out of control before you start to treat, the problem is that the roaches can reproduce almost faster than they die.  To slow down the reproduction cycle you should use an IGR (Insect Growth Regulator) with the roach gel.  Also, the roach gel will only work if you do not leave out other food to compete with it.  You must take out trash at night, sweep floors, do not leave any dirty dishes in sinks at night, etc.

    This product works!!

    By Amer on 09/08/2008

    Verified Purchase

    This product works! I've spent hundreds of dollars on roach foggers, bait and sprays from Home Depot & Lowes and nothing worked. After using Maxforce Pro Roach Killer Bait Gel I noticed a lot less roaches in my kitchen in about 2 weeks and almost none in about 3 to 4 weeks. I also wanted to thank everyone on here for writing reviews about this product (and others) and the knowledgeable staff that recommended this product to me.

Is Maxforce Pro Roach bait safe to use with pets in the household? Cats in particular.
Maxforce Pro is safe to use in a home with cats and other pets when used as directed on the product label. Maxforce Pro is for use only as a spot or crack and crevice treatment for the indoor control of Cockroaches in residential areas and only in areas inaccessible to children and pets. You should place small dots of bait every 10-12 inches in kitchens and bathrooms directly in cracks and crevices on and under counter tops, in cabinets, cupboards, drawers and food pantries, around dishwashers, refrigerators, sinks, pipes and baseboards. Do not place bait on food prep surfaces or in places that you will frequently touch or in places that are frequently washed. You can also use Maxforce Pro in other rooms in cracks and crevices if you are seeing roach activity in those areas.

How often do I need to re-apply the Maxforce Pro Roach Bait gel?

I live in an apartment. I use stuff from the market, and it stops them for few weeks but they start coming back again. How long will one application work?

The Maxforce Pro Roach Bait Gel will stay effective for several weeks after it is applied. It will not prevent new roaches from moving in, it will only kill the roaches as they happen to eat it. We recommend that you use caulk or other suitable material to close any crack, crevice or gap around baseboards, pipes, wires, cables, cabinets, vents, door frames, window frames and any other place where insects could enter. This will help stop the roaches from moving from adjoining apartments through the walls and into your apartment. In addition, you should spray around the perimeter of each room with a good insecticide such as Demon WP and you should use an insect growth regulator (Gentrol) to control the breeding cycle of the roaches that have already entered your apartment. We do have a roach control kit that contains all of the products you need to get rid of the roaches you have now and help keep them gone, the Roach Control Kit 2.
