If you were to use one product for prevention and/or treatment of bed bugs, then we would recommend Bedlam. It is our most popular product and it will kill adult bed bugs as well as bed bug eggs. D-Force will not kill bed bug eggs, and there is a concern of bed bugs becoming resistant to D-Force. If you have only found bed bugs in your bedroom then it would probably be OK to only treat that room, but if bed bugs were found all over different areas of the buildings, then you should treat the whole unit for adequate protection. Also, if you have been sleeping on a couch instead of your room then you would want to treat the whole apartment. You should use one of our Bed Bug Kits for optimal results.
Yes, D-Force HPX will kill the moth larvae, and could possibly kill the adults should they come in contact with the treated surface long enough to get a lethal dose. This product can provide up to an 8 week residual, and it kills on contact, as well.
D-Force Aerosol can take longer to dry if overapplied. Treated areas should just be lightly sprayed, not soaked to the point of runoff. If there is still some left after a few hours it would be best to wipe away the excess.
Then you want to flush out the area with an adulticide like:
CB Air Devil HPX is a cypermethrin residual contact kill aerosol that HPX is specially formulated to clear out large numbers of target insects fast, and provides up to 3 months of protection. For treatment of millipedes, spray CB Air Devil around doors and windows and other areas where millipedes may be found or where they may enter premises. Spray baseboards, storage areas and other locations. Repeat as necessary.
Next you want to do the perimeter treatment indoors and out.
Demand CS, Suspend SC, and Cyper WP are residual liquid formulation pesticides that are added to water and applied with a low-pressure sprayer can provide a powerful residual that continues working for 4 to 8 weeks following application. These residual liquid formulations can be sprayed along the outside perimeter of the home (especially under and around eaves, decks, patios, and window shutters), and inside along baseboards, in cracks and crevices, and other potential millipede harborages. You will know the residual is working because you will begin finding only dead millipedes rather than live ones.
That is a difficult and hard place to treat spiders. You can use a contact kill spray such as Sterifab to kill any of the spiders that you see. We recommend that you vacuum and then use D-Force HPX that is labeled for use in automobiles. We also recommend contacting Your Local Cooperative Extension Office for help on which products to use for spiders in your car.
