Cy-Kick CS is not labeled for bird mites.
It is important to be absolutely sure you are actually dealing with bird mites. We would recommend having a pest control company come out and do an inspection and/or getting a sample and taking it down to your local cooperative extension office. In the mean time, there are things that can be used for your situation. Sterifab can be used on couches, chairs and other upholstered furniture where you may spend time resting. This is a contact kill and will not leave any residual. Onslaught can also be used for a faster knockdown. Thoroughly apply as a fine particle broadcast spray using a hand pump sprayer to infested rugs and carpets and other cracks and crevices around the perimeter of each room. This is a residual and can be used every 90 days indoors. You can also put all clothes through the dryer on high heat to help kill mites and their eggs
We have had many customers use the above recommendations with great success. Most customers report that it can take several months to get rid of all of the mites. Finding and removing the source of the infestation is very important and is the key to getting rid of the mites for good.
Cy-Kick is toxic to bees and fire flies. You would want to be sure to apply when bees are not pollinating. Or in areas that fire flies may not be populating.
Any of the fogging solutions, like ULD BP 100 could be used to fog for spiders in a crawl space. Any spiders that are exposed at the time of the fogging will be eliminated, but that is it.
For indoor use, instead of fogging we recommend spraying a residual insecticide such as Cy-Kick CS into the cracks and crevices around door and window frames, baseboards, under appliances and in places where cables, pipes and wires enter through the walls.
You can also use Cy-Kick CS to spray around the exterior on the foundation, door and window frames, around places where cables, pipes and wires enter into the structure and any other crack, crevice or hole where insects can gain entry. By using the residual insecticide inside and outside you will be eliminating hidden spiders that come out to hunt and also the insects that they are there to prey on. By eliminating the spiders' food source, you will be forcing the spiders to move out and you will be making the structures less desirable to other spiders looking for new hunting grounds.
