Yes, Demon Max and Archer IGR can be tank mixed and sprayed at the same time.
Any of these insecticides would be a good choice for perimeter control of crawling pests. You would not need to mix insecticids as these all have similar active ingredients, and using too much may cause pests to avoid the area rather than coming into contact with the application. An advantage to using either Demand CS or Temprid SC is that these are both water-based, rather than oil-based insecticides. They will have much less odor and can be used safely indoors as crack and crevice and/or spot treatments.
Please see our General Pest Prevention Guide for more information.
For Termite Treatments, you will need to apply products much differently. Please view our Termite Pest Guide for more information about how to Identify, Inspect, Treat, and Prevent Termite Infestations.
Demon Max is labeled for milipedes, and will eliminate the ones that are in the area currently. There are a few things that you can do to possibly stop them from coming to the area to begin with. Habitat modification is key to reducing your milipede population. Since they live in and eat organic matter, try to remove as much excess organic matter as possible like piles of weeds, leaves, etc. Over-mulching and overwatering also can create damp environments for many pests, not only millpedes. Avoid overwatering, and use rocks or other materials instead of mulch if possible. Always pick fruit and vegetables,if they are in your area, as soon as they are ripe to prevent millipedes (and other pests) from using them as a food source.
When making an application of Demon Max, everyone except the applicator should be out of the area where it is being applied. Once the application is done the treated rooms need to be left vacant until the product has time to dry.
No, Demon Max is not labeled for use on fruit trees or anything edible and will not treat disease. We would recommend contacting your local cooperative extension office to determine what is causing the leaves to curl on your lime tree so that we can recommend an appropriate product for you.
Demon Max is safe for pets and humans once dry. As long as it has had at least 6 hours of dry time before rain or irrigation it wont be of any concern for pets if they go through an area that was sprayed that becomes wet.
