I posted review 1 year ago, giving them great review. I thought the issue was resolved, but unfortunately, it wasn't.
Problem started 2 years ago when squirrel gnawed the ventilation cap and entered from the top, the pesky critter also found opening through small gap underneath living room extension ( House builder added extra living space by extending floor out from the foundation 6' inch off the ground, the underlying section became entry point for critters)
Pestokill did a really nice job sealing off vent cover, but did not fully seal off all the gaps at the bottom of the elevated extension . This year the critter returned from the bottom side again.
Pestokill added one way door at a small opening that they left behind a year ago, but for whatever reason the critter did not come out. The critter eventually died inside the walls and my wife and I had to deal with foul odours followed by flies in the weeks to come.
Overall, staff is very friendly, I like the people I dealt with. Unfortunately, at the end of day, problem just wasn't resolved right.
