Once Archer IGR is dry, it is safe the dogs to be on the lawn and chew the grass.
We would recommend treating the entire lawn. Archer IGR is labeled to be used in pet dwellings so this will be safe to use there as well. We would also recommend using an insecticide with Archer IGR, such as Onslaught. Archer IGR is just a growth regulator. It will not kill the fleas. It will only stop them from reproducing. Please let us know if you have any additional questions.
Archer IGR would be mixed at .5 to 1 oz per gallon of water. You can mix Bifen IT, Archer, and Exciter together in the same mix everytime you spray. Both Archer and Bifen can be used every 14 days outdoors for active infestations. Exciter is a quick contact kill only so can be used more often if needed.
Yes, Archer IGR also has a 7 month residual for ticks. Please see our tick guide for more information in treating: How to get rid of Ticks.
Archer IGR should NOT be applied directly to any animal including dogs. Please check out our Flea Treatment Products that are safe for applications on pets.
It is possible that Archer IGR could stop the lifecycle of earthworms even though it is not labeled for them. Earthworms are considered beneficial insects and will not be found on any label.
We do carry green products, such as Essentria IC3, which is made with items that naturally occur in nature, such as rosemary and peppermint oil. This will likely last about two weeks outdoors because it will break down in the elements outdoors more quickly then a synthetic product.
Archer IGR should be used every 10-14 days when treating for fleas. We would also recommend that you use an insecticide in combination with this product for fleas, such as Temprid SC. Both of the products will be used every 10-14 days. Be sure to vacuum daily in between treatments as well. Please see our Flea Treatment Guide for more tips and information.
Archer IGR is not labeled for mealybugs. When treating for mealy bugs, you could apply TriStar 8.5 SL, and you will use 7.5 ml (0.25oz, 1.5 tsp) per 3 gallons of water for effective control. The Tristar bottle will measure as low as 5 ml in the built-in measuring reservoir. It is suggested that you mix a surfactant with the TriStar when treating for mealybugs for better control. You can use the Non-Ionic surfactant we carry at the rate of 1-2 teaspoons per gallon of water. Do not make more than 4 applications per year. Do not reapply more than once every 7 days. To determine if application is necessary, monitor pest densities.
Talstar P is labeled for the treatment of fleas outdoors only. It can be mixed with Archer IGR. They can be tank mixed at one ounce for each product to one gallon of water per 1,000 sq ft. It can only be applied to indoor cracks and crevices. Fleas will be on the open floor surfaces so it is important to apply a product to those surfaces indoors for eradication. We do carry a Outdoor/Indoor Flea Kit. Please take a few moments to review our treatment article How to Get Rid of Fleas.
