Termidor SC is not labeled to be used anywhere near grazing animals and would not be recommended.
Once Termidor SC is applied it can take up to a month or 6 weeks depending on ant species and size of the colony. As long as you are seeing dead ants the product is working. Should you start to see live ants again then there may possibly be a satellite colony in a wall void that needs to be spot treated or baited.
Please see our How To Get Rid if Ants Guide as well for more tips.
If you pressure wash over the areas where you have applied the Termidor, you will remove all of the product from the exterior and by extension stop from the product from being effective. You should only pressure wash the exterior if you have experienced complete results from using Termidor and do not need the product in place any longer.
Suspend SC will only kill the ants that contact a treated surface and would need to be applied every 30 days outside and 90 days inside. Termidor is the # 1 choice for ant control around the home. Termidor is a non-repellent insecticide that works with a delayed reaction amd also has a transfer effect. That means that ants cannot tell that the Termidor is there and will walk right over it and then pick the product up on their bodies and inadvertently carry it back to the colony, then through normal social interaction the ants spread the Termidor and wipe out the colony.
Termidor only needs to be applied two times per year and is effective for a wide variety of insects including ants, centipedes, roaches, spiders, silverfish, wasps and many other nuisance insects. You will need to apply Termidor SC 1-2 ft up the foundation and 1-2 ft out onto the ground, around door frames, window frames, places where cables, pipes or wires go through the wall and any other crack or crevice where the ants can gain entry into your home.
You cannot use Termidor inside for ant control so Suspend would be the better product if you needed to treat inside.
Termidor SC can be purchased by anyone that does not live in a restricted state and at this time Texas is not a restricted state. In most instances you are allowed to use Termidor SC as long as you are using it on your own property and you are not treating say your neighbors house for profit.
Termidor SC does have a slight odor though we have never had a complaint that the smell was overwhelming.
You can apply Termidor SC as long as the ground is not frozen and make sure that it does not rain for 24 hours minimum after you do your treatment.
According to BASF the only times you cannot treat is if precipitation is currently happening or if the soil is over-saturated with water, frozen, or in conditions where runoff or soil movement from the area or treatment site will occur. It would be great to not have rain after your termite treatment, but certainly not something that is “needed (or a must)” for the product to be efficacious or provide long-term residual activity/structural protection.
