Ground moles are not typically dangerous. They're not known to carry rabies like many other wild animals, such as raccoons, skunks, and bats. And they don't typically bite humans, although it's possible if they feel threatened. If you do get bitten by a mole, it's best to see a physician to be safe, but most often, the bite will heal on its own unless it gets infected.

Wasps are attracted to three primary things: Bright colors, food sources, and softened wood they can use for nests. They are more active in warmer months, which is when outdoor flowers and dinners also become more common. You can decrease the attention of wasps by keeping trash bins closed and avoiding bright flower colors in furniture or tablecloths.

Tree sap is not usually dangerous to humans or pets. But some trees do produce dangerous sap. Notably, ash, birch, cedar and similar saps can irritate the skin but aren’t dangerous. Sap from trees like the Brazilwood, Mahogany, Milky Mangrove or well-named Poison Walnut can be corrosive, cause nausea, or trigger those with asthma. But for most backyard trees, protective equipment like a sturdy pair of gloves should be fine.

Exterminators use residual insecticides in either liquid or powder form to kill scorpions. These insecticides are applied directly to visible scorpions and their common hideouts and entryways in a home to kill them and prevent future infestation. Exterminators will also use diatomaceous earth at entryways to slowly kill scorpions that enter a home later.
