Boracare is not labeled for roaches. It would be best to use products that are specifically labeled for them, such as the ones that are found in our roach control kits.
Boracare can be used as long as the tiki hut is not over water and the wood is not sealed or stained. The ratio that you will use the product at the 1:1 ratio. You will need to inject the product into the kickout holes and then topically spray. You will need to spray all the wood. Be sure to seal the wood on the tiki hut once the product has dried completely.
If the dining table is raw wood with no paint or finish on it, yes Boracare can be used. You will use it at the rate of 1:1. This can either be sprayed on or painted on. You can also use Jecta in the holes where you have seen activity if the wood does have finish or paint on it. You must finish food-handling surfaces such as dining tables that have treated with Boracare.
BORACARE can safely be used on the board as long as you stain after it has dried.
Boracare should only be used to prevent carpenter ants. We do not recommend using it to treat and active infestation. You can treat and active infestation by using something like Carpenter Ant Bait or by treating directly with a product like Phantom Aerosol or Termidor Foam.
Yes, you can treat the same wood with the Boracare. The previous treatment with Timbor will have no affect on the absorption. Both products are borate-based and become one with the wood after application.
When treating for powder post beetles, it is important to know that you may still see some beetles emerge even after you've treated with Bora-Care. This could be because the product may not have reached the center of the wood yet, or because there were still some dormant beetles at the time of application. With Bora-Care, the powderpost beetles do have to consume the wood in order to die. If you are still seeing activity, this means they are consuming the wood and dying. Any wood treated with Bora-Care, however, will be protected from any new damage. There is no need to treat again.
Boracare can certainly be applied to a deck and it lasts for the life of the wood if it is not exposed to rain, continuous water or ground contact. The amount of time Boracare lasts in the wood will depend upon those factors. In your case, we would recommend using a sealant of some kind after the application of Boracare. Do not expose treated exterior wood surfaces to rain or snow for at least 48 hours after treatment. For longer performance, exterior wood surfaces will require a topcoating with a water-resistant finish such as paint or exterior stain. Apply within 6 weeks of treatment. Boracare must dry completely (at least 48 hours) before applying any protective topcoat. If there is a current infestation, you will do a 1:1 application of Boracare. If this is just for preventative measure, you will do 5:1 application. Make sure the water is very hot when you are spraying it.
Bora-Care is a very safe product and it is considered a green product as well. Typically, it takes about an hour for the surface of the wood to dry. After application has dried completely, it should be perfectly fine for children and pets to re-enter the house.
You can use Boracare on pressure treated wood as long as there is no stain, sealant, or paint on the wood. If the wood treated with Boracare is outside exposed to the elements, then you want to apply a water sealant after the Boracare has dried.
