Town and Country’s proactive plan provides a full 6 month guarantee on each and every residential house. No one that we know of will provide a guarantee of six months. Most other companies only provide a 30 day guarantee. While these companies are still trying to figure out how to kill a bedbug, we have lept through the black hole. Most bed bugs are killed on the first day, plus we prevent re infestations by applying our proprietary residual treatment.
