Altriset Termiticide will still be effective as long as it has had time to dry completely before any rainfall.
We apologize but we would not recommend that you spray the firewood with any insecticide. The manufacturers do not recommend this. Any insecticide should not be breathed in, and when burned these toxins can become airborne. It would be suggested to not burn the wood that you treat with anything. Altriset is only labeled to be applied adjacent to structures but you could spray Dominion 2L around the firewood only on the ground but be careful to not apply to the firewood.
We recommend that you plant vegetables at least 15 feet away from areas treated with Altriset Termiticide.
