As the exterminator is telling Doug that the price went up, he drops his bug cup with the blue lid from his tool belt. As he is leaving the room, the cup is back on his belt without him ever picking it up.

Deacon says the Chinese food was good and asked where it's from. Danny say it's from Szechuan Village. Deacon says he needs to remember that, but in the previous episode he and the other guys rented the apartment next to Szechuan Village and ate there many times.

Carrie tells Doug to quit bothering her, she's "not in the mood tonight". Turns out it was bed bugs. You cannot feel bed bugs crawling on you (although the exterminator told them those were an especially large variety).

An exterminator would never lay on a mattress infested with bed bugs. Bed bugs are readily spread from place to place on clothing.

An exasperated Carrie, on the phone, asks the exterminator how long it's gonna take him "to find the queen". Bed bugs don't have a queen.

Bed bugs cannot be effectively removed from a mattress. Mattresses infected with bed bugs supposed to be sealed in plastic and burned or buried.

As the exterminator switches on his head lamp to look at the bite on Doug's leg, the light goes right off.

Doug and Carrie decide to sleep in their Jeep for the night to avoid the poison used by the exterminator. The Jeep is parked on the road allowing neighbors to easily see them. It is never explained why they didn't just sleep in their detached garage. Even if they ultimately decided to sleep in the Jeep, why not park it in the garage out of view of prying eyes?

Right before Doug and Carrie leave the house after she sets off the bug bomb, Doug says he's waiting for his Hot Pocket to be done. When they show it in the microwave you can tell by the shape of the product, and the design on the cooking sleeve, that it is clearly not a Hot Pocket.
