The reason Bayer Fipronil is so good is they do not die right away. They track the chemical back to the nest first. In many countries an ag supply company will sell it in pure form. Must dilute 50 to 1 in water, OR use 70% ethanol. The ethanol evaporates and carries the chemical too. Look for other sources of this chemical in things like dog flea powder. That you would use in mixture like 2 to 1. You must find the exit hole. Then take syringe and inject liquid into hole.
Find the hole by looking for the pellets and the flying termites. Use big sheets
of clear plastic to isolate areas. So clean up an area with dead termites, seal it off, then see if you get any new flying termites in that area after a few days. If so, you found an area. You just need to locate the hole.
Sometimes you can isolate an area and then spray a bunch of the chemical mix inside. You then hope enough evaporates and then finds a hole you failed to find.
If you have heavy infestation you may need to start drilling to trace a hole you located. This allows you to use a vacuum cleaner to suck out the pellets and the inject chemical in many places.
Place a piece of blue tape on each hole after treatment. This helps you remember to treat that hole again and again. It also helps you focus on finding new holes.
REMEMBER A nest can go over a year without sending out any new flying termites. So dont be surprised if this process takes years. The good news it is new nests that take this long.
begin after water has dried out in channels. Minor repairs
in heavy woods can be as simple as drilling to trace the channels, vacuum out pellets and dead termites, find highest channels, and then inject slow cure concrete crack epoxy
. It takes several days to cure and will follow channels.
In softwoods with large amounts of voids, you may get away with using a three part injectable foam for non structural areas. The area is likely weaker so a top layer of new orientated fiberglass
is probably needed.
Very big damage where whole areas of plywood
are gone require removal
of that plywood and replacement.
a termite infested boat is a battle, however with chemicals, time and repairs you can do relatively easy, you will likely save a bundle over new boat costs.
