Gentrol IGR Concentrate - Questions & Answers

Yes, Gentrol IGR Concentrate can be tank mixed with Temprid FX.

The mixing ratio for Demon WP is one to two packets per gallon of water. The mixing ratio for Gentrol IGR is 1 fl. oz. per gallon of water. You will fill the tank up halfway, put the products in, fill the tank up the rest of the way and agitate. Be sure not to leave chemicals inside your sprayer for more than 24 hours because it will decrease the effectiveness of the product.

Gentrol IGR in any form will not affect a dog, child or adult in any way that would harm them, or keep any of them from being able to reproduce. The Gentrol is specifically formulated to only affect the juvenille growth hormone that only insects posses and hinder it from working properly. 

 

Gentrol IGR will not kill insects, it only prevents them from reproducing. You should use other insecticides, such as Suspend SC, in conjunction with the Gentrol Concentrate. In general, if you use the recommended products together as advised you will start to see a reduction in insects within a week or two. However, it may take a month or so so see full eradication.

There are no special precautions to take for pregnant women when using Gentrol IGR. We do recommend that you let someone else apply any insecticide or IGR and wait for the products to dry before you go back into the treated areas.

You can treat the entire house (in specified areas) in case the bedbugs migrated to other areas of the house where they have yet to be detected.

Yes, you can mix Gentrol and Transport Mikron together. You want to mix 1.25 oz Transport Mikron with 1fl oz Gentrol into one gallon water.

There are no special directions for pregnant women. Follow the instructions on the product label. The label states that you should spray once a month for best results. It is also very important that the source of the infestation (where the damaging larva is harboring) is discovered and eliminated, not just the visible adult insects you see wandering around. Until you find out what that is and deal with it you will continue to get more of the carpet beetles emerging from hiding. Carpet beetles may be as likely to feed on grain based food materials as they are on animal byproducts. Pet foods stored in forgotten places, baking goods left too long in the cupboard, rodent baits tossed in the attic - all of these are quite susceptible to carpet beetle feeding. Plus, you also have the typical carpet beetle diets of dead insects (wasp nests in the attic, dead insects in window sills), feathers (bird nests, dead birds), hair (dead rodents, wool products, trophy mounts), and other things made from animal byproducts. Once the source of the infestation is removed or cleaned, use Suspend SC and Gentrol IGR once a month until all of the beetles are gone.

Gentrol IGR Concentrate has a shelf life of about 3-5 years if kept out of extreme temperatures and direct sunlight.  It can be applied more often then ever 4 months depending on the pest you are trying to control so it should still be effective in that time.

Gentrol IGR is not labeled for fleas and is not recommend for use outside.  For outdoor flea control you should use our outdoor flea kit, which comes with an IGR that is labeled for fleas.  IGR's do not kill adult fleas though, they only prevent immature fleas from maturing.  The outdoor kit also comes with a product to mix with the IGR that actually does the killing of adult fleas. 

The Gentrol IGR supplemental label states "To treat bedbugs, apply to harborage points mentioned in general treatments; in addition, under beds, bottom side of box springs (do not treat linens and mattresses), under and behind night stands, to points where carpet and wall meet, cracks in cove base, molding, and other areas where bedbugs harborage." Treating the underside of the sofa should be just fine, just be sure not to get any spray on the areas where people will contact it. For more sensitive areas you can use Bedlam and Steri-Fab.

Gentrol IGR Concentrate is pet safe if used as directed.  Pets must be kept out of the area during application but can return as soon as the product is dry. 

Gentrol IGR once dry is safe when used as directed. The dried residual will not have any effect on people or pets even if they touch it or if pets contact an area after application while they are wet, it does not reconstitute. You should apply the Gentrol IGR as directed on the product label, directly into cracks and crevices around door frames, window frames, baseboards and under appliances. There is no need to spray the entire carpet and it is not labeled to do so. All pets should be out of the area during the application, and they can safely return to the treated as soon as it has dried.  By applying the product directly to cracks, crevices, voids and other inaccessible areas you will be limiting anyone's exposure to the product.

Gentrol (along with most other liquid concentrates) should be used or discarded within 24-48 hours at most after mixing.  This is because the active ingredient will start to break down after this point and cause the solution to become less effective.

Ortho Home Defense is a ready to use product so it is already premeasured.  Gentrol IGR Concentrate, once mixed with water, needs to be used within 48 hours of mixing with water.  Unless you plan to use the entire gallon of Ortho when you mix it with the Gentrol, we would not recommend mixing the 2 together.

Gentrol IGR has a mild petroleum solvent odor and is completely safe for kids once the product has dried. When applying using a hand pump sprayer, it usually takes 1-3 hours to dry and the kids would need to be out of the room while spraying. When treating in cabinet & pantry areas, follow the instructions per label listed below.

Pantry/Cabinets, Small Food Storage Areas: Apply as a surface spray, crack and crevice spray, or spot treatment to pantry and cupboard shelves or other areas where food is stored. Prior to spraying, remove all food containers and foodstuffs. Do not replace food containers or foodstuffs until spray has dried. Do not store food in open containers in treated pantries. Destroy any infested food packages to ensure proper control.

Nyguard IGR is not labeled for bed bugs. Temprid SC can be mixed with Gentrol IGR. It will stop the bed bugs from reproducing. You will need to use Gentrol IGR every two weeks when you spray the Temprid SC along the baseboards and cracks and crevices. Please let us know if you have any additional questions.

You can use Gentrol IGR in commercial facilities, food prepartion facilities, schools, and homes as a general surface spray, fogging, spot, or crack and crevice application. Reading the product label will help you determine the appropriate places to apply Gentrol as different pests will require different applications.

No, Gentrol IGR is not labeled for mosquitoes nor can be used outside.  The most recommended IGR for mosquitoes is the NyGuard IGR.  It is photostable outside and also works for many other insects as listed on the product label.

If you are using only a 1/2 gallon of water, you should use only 1/2 oz of Gentrol. The efficacy will not be lost by making this mixture. Be sure to put cap back on concentrate.
