Today my landscaper put down mulch surrounding my home. A few hours after I noticed a swarm of termites coming through front door from the outside. I quickly got rid of them and placed boric acid traps and have a termite stake kit to install. Upon further reading, I noticed there should be a 6-12 inch buffer between mulch and foundation of home. However the mulch is layed right up to the foundation. Do I have to get rid of mulch now to avoid infestation?
