Dominion 2L Termiticide Concentrate should not harm the lawn at that rate. We recommend that you treat with 0.6 fl oz per 1,000 sq ft on future applications per the product label instructions. If you do show signs of damage, you can reach Control Solutions at 281-892-2500 for assistance.
It all depends on how far away the well or cistern is away from the property. Here is the verbiage off of the instruction label for Dominion:
TREATMENT AROUND WELLS OR CISTERNS: Do not contaminate wells or cisterns.
Structures With Wells/Cisterns Inside Foundations: Structures that contain wells or cisterns within the foundation of a structure can only be treated using the following techniques:
1. Do not apply within 5 feet of any well or cistern by rodding and/or trenching or by the backfill method. Treat soil between 5 and 10 feet from the well or cistern by the backfill method only. Treatment of soil adjacent to water pipes within 3 feet of grade should only be done by the backfill method.
a) Trench and remove soil to be treated onto heavy plastic sheeting or similar material or into a wheelbarrow.
b) Treat the soil at the rate of 4 gallons of solution per 10 linear feet per foot of depth of the trench, or 1 gallon per 1.0 cubic feet of soil. Mix thoroughly into the soil taking care to contain the liquid and prevent runoff or spillage.
c) After the treated soil has absorbed the solution, replace the soil into the trench.
Structures With Adjacent Wells/Cisterns and/or Other Water Bodies: Applicators must inspect all structures with nearby water sources such as wells, cisterns, surface ponds, streams, and other bodies of water and evaluate, at a minimum, the treatment recommendations listed below prior to making an application.
1. Prior to treatment, if feasible, expose the water pipes) coming from the well to the structure, if the pipes) enter the structure within 3 feet of grade.
2. Prior to treatment applicators are advised to take precautions to limit the risk of applying the termiticide into subsurface drains that could empty into any bodies of water. These precautions include evaluating whether application of the termiticide to the top of the footer may result in contamination of the subsurface drain. Factors such as depth to the drain system and soil type and degree of compaction should be taken into account in determining the depth of treatment.
3. When appropriate (i.e., on the water side of the structure), the treated backfill technique (described above) can also be used to minimize off-site movement of termiticide.
Dominion 2L would not work for elm bark beetles as it would not reach to the areas of the trees these beetles infest. Effective treatment involves killing the beetles before they bore into bark in fall and when they first emerge in spring so protecting healthy trees is best. Timing is critical to reach the pests before they're under the protective bark. You can use a product like Permethrin SFR for this.

Dominion 2L is not a detterent, it is a non-repellent. It is not labeled for carpenter bee control. It can be applied a foot up and a foot out directly up against the structure for crawling insects that forage inside the structure and in the soil trench/drilled holes for termite treatment and protection. Delta Dust can be applied to cracks and crevices, voids and the holes that the bees bored in the wood and/or siding. Please apply a liquid insecticide concentrate to the structure's surface for eradication. I have included an article below that I you will find helpful.
You need to get the Dominion into the ground, so you would typically want to drill holes in the tree stump, and around the tree stump into the ground, and then inject the Dominion inside any holes. It will touch the termites that are inside and underneath the stump and eliminate them completely.
Dominion or Termidor could be used in the trench around the house and would be great to do so. Termidor would last longer in the soil, 10 years or more whereas Dominion is about 5-7 years.
Dominion 2L should only be applied to the exterior of the structure for ants, termites, soil drenches etc for listed uses on the product label. It should not be mixed with Talstar P. Talstar P can be applied quarterly to the interior cracks and crevices and exterior listed areas. Dominion 2L is a non-repellent, but Talstar P is not, so mixing together would not be advised.
