I'd like to make a suggestion or 2 being having 12+ years experience as a Pest Control Manager.
1. Fleas for new type of bug and the area a dog house, dog bed or kennel around the yard. Can even have a cat roam the yard like the birds do and drop them.
2. A chair or couch cushions of some sort, for Bed Bugs these guys are nasty little things, and you can get even more tricky with them. Their behavior is very sporadic with other insect and being attracted to the carbon dioxide humans release from exhaling.
3. Brown Recluse for another spider, these are extremely dangerous and love the wooded areas.
I can name and list many more insects and their habitats if anyone wants to reach out to me.
