Treat termites in my speaker enclosure

Fipironil is sold as water soluble concentrate, one trade name is Regent (Bayer).
Bayer also sells a gel called Goliath, which contains fipironil, a small amount of gel, about the size of a black eyed pea, is sufficeient for a speaker as precaution, put about so much in 6 places per cabinet in the first phase.
Once clear, one is enough, lasts about 6 months here, 42 C ambient, 80% humidity, in my city.

Fipironil and Chlorpyriphos are the generic names of the compounds used as termite treatment pesticides.

Fipironil is the right choice. It is sold as water soluble concentrate, you can mix it straight from container in oil paint thinner (mineral turpentine oil) for use on wood.
It would be great if I can mix it into oil paint thinner because that would not cause my plywood to delaminate. But I don't understand why it mentions both "water soluble" and "mix it in oil paint thinner". So is it a water solution or a turpentine solution?
 
Another seconder for Fipronil.You can make baits using scraps of pine or rolled up cardboard soaked in it and bury it around your house.I have a brick and steel roof framed house but still had termites eat out my skirting boards which were a non resistant species.After baiting and spraying around the house with Fipronil they have not been back.
 
Fipronil is sold mostly as EC (Emulsifiable Concentrate) in liquid form.
Intended for use in water, but for wood you can mix with paint thinner instead of water, straight from the container.

Check the strength, here 5/10/20% concentrations are sold, get the highest one available.
 
Do you have a name for a product available on Amazon USA. I searched for it. Amazon returns way too many results for repellents not containing Fipronil. Also, some products which specify to contain Fipronil seems to be aqueous, hence I am not sure if this is a product which can be mixed with thinner.

The cost to get a liquid from Amazon are quite high because of shipping restrictions. Still Amazon is my only option. It is not I am too lazy to search, it is I am unsure of what manufcaturers specify.

Ask at pest control service or farm supplies dealer.
Pretty common.
Normal use is water dilution for fields and building foundations.
Thinner is practical application innovation by local pest control agencies.
