Yes, both Conquer Insecticide and Precor IGR Concentrate will continue working after they are dry. While we do recommend retreating at 2-week intervals for active flea infestations, Precor can continue working for up to 7 months indoors (provided carpets are not steam-cleaned or shampooed). While Precor may not prevent eggs from hatching at all, it does prevent immature fleas from reaching adulthood.
No, Precor IGR is not for use on animals; it is for use in structures only. You can use Petcor Flea Spray on dogs and cats at least 12 weeks of age.
Precor IGR Concentrate can be mixed with just about any type of insecticide. You would mix 1-2 packets of Demon WP and 1 oz. of Precor into 1 gallon of water.
It is recommended that you keep pets out of the area while Precor IGR Concentrate is being applied. Once the product has dried completely, it is safe for your pet to return to the area. Please contact your vet if you have any concerns.
Precor IGR Concentrate is safe when used as directed on the product label. People and pets should be out of the treatment area until the application is dry.
You can safely mix Precor IGR with any insecticide labeled for your application needs and apply as a broadcast spray indoors to control pre-adult fleas - up to seven full months. It does not work outside in direct sunlight.
One container of Precor IGR concentrate will treat 1500 square feet. The amount of product used will depend on how much area you are treating. This product is only a growth regulator so it will take time to eliminate fleas. We generally recommend that you use an insecticide as well in combination with the growth regulator. Be sure to treat every 10-14 days with an insecticide until you no longer see activity.
Please check out our Flea Guide for tips on how to treat and prevent fleas.
Precor IGR Concentrate is a great IGR labeled for fleas, but it is not for use outdoors as it is not photo-stable. If you are treating for fleas outdoors you can use our Outdoor Flea and Tick Kit. This kit contains professional products to help prevent and treat infestations of fleas. Cyzmic CS is a versatile insecticide concentrate with two active ingredients, providing both a quick initial kill and long-term residual control of adult fleas. Archer Insect Growth Regulator prohibits the development of immature stages of fleas, effectively interrupting the breeding cycle of target insects. These concentrates can be diluted and applied together to save time and energy. Most of your flea control will come from the initial application, but it may take several treatments to fully eradicate a or flea population. For heavy infestations, you would want to reapply after 14 days to catch new adults that have emerged or insects that animals have carried into the treatment area.
The dry time for Precor IGR is usually 1-2 hours, depending on how heavily it was applied.
As with most any concentrate, it is recommended to use all diluted Precor IGR solution within 24 hours of mixing since the product is not designed to sit in solution and still remain stable and effective.
Once Precor IGR is dry, there is no worries about harm to a pet that lays on or licks any surfaces where you have sprayed.
Yes, Precor IGR Concentrate may be stored for later use. It will last 3-5 years from the date of purchase if stored at room temperature.
Yes, Precor IGR Concentrate can be used indoors with children and pets. Keep kids and pets out of the treated area during the application and until the application has completely dried. This is typically within an hour or so. Spray applications should be made till surfaces are slightly damp, not overly saturated or soaked.
Keep in mind, Precor IGR Concentrate is an IGR only and not an insecticide. This will not kill fleas by itself and will need to be tank mixed with an adulticide labeled for fleas to be effective. Options for insecticides are Onslaught or FenvaStar that are labeled for broadcast applications to carpets, rugs, undersides of furniture, cushions, etc.
Please view our Indoor Flea Kit and Flea Treatment Guide for more information.
While Precor IGR shouldn't harm fish if used appropriately, you would need at miminum to cover the fish tank while spraying and until everything has dried and settled. If its easy to remove the fish before spraying then I would do so, but if not, just covering them with a sheet or fabric to protect from particles getting in the water or filter would be sufficient.
A fan spray or a mist when used on most standard garden sprayers is fine for your indoor application of Precor IGR. If you feel you are getting too heavy of an application you would either need to move faster as you treat or create less pressure in your tank to have the product not come out of the nozzle at such a high rate. If you find that this is still heavier than you would like to be spraying indoors for your personal preferences, we would recommend swapping to an aerosol can like Precor 2625 for indoor use instead to get that light application.
Yes, Precor IGR Concentrate and most insect growth regulators (IGRs) can be tank mixed with an insecticide labeled for the targeted pest and applied to the areas listed on the product label.
