Termites survived fumigation

[Nathan Olds]

When i purchased my first property in June, there was evidence of drywood termites so I got the property fumigated before a tenant moved in. About 3 months later, the drywood termites are back and active. Has anyone had this happen before where fumigation does not kill off all of the termites? 

The warranty covers getting it fumigated again but because there is a tenant now living there, i would have to pay to put her and her dogs in a hotel for several days or I can wait until her lease ends and fumigate between tenants. Any thoughts?

Actually it's a little worst than that...dry wood termites can survive for about a week after fumigation. Activity can actually increase during that time.  But here's the worst part:  new ones move in.  You were smart to engage a contractor who will re-treat.  Most here in my market have contractual clauses that state "they're dead when we leave - what happens after that is on you."  If you were in a cold climate, you could probably wait without concern for ongoing lunching of your property.  But with our "Vietnam-like weather" (hot, wet, humid) it's the perfect storm.  What you can do in lieu of fumigating right now is:

1. Remove the source/caulk like crazy:

"Drywood termites can be avoided by making sure firewood and scrap wood is stored at least 20 feet from the home. Drywood termites form new colonies by gaining access to wood through small holes. As a drywood termite treatment tactic, seal all cracks and crevices in a structure."

2. Spot treat by using an over-the-counter product like Terminate; there are spikes and sprays that work fairly well and serve as that stop-gap measure until you fumigate again.

And, yes, I am thoroughly embarrassed that I know this.  Been there, done that, live this everyday at my properties and my clients'.  

May the force be with you...
