Vacuum spiders, webs and egg sacs, set sticky traps along the walls, clear clutter and seal the gaps they walk through. Sprays only kill the spider you hit. About $26 in supplies; a pro charges $100–$500.
A small paper wasp nest you can reach from the ground is a DIY job: spray it at dusk, wait 3–4 days, then knock it down and bag it. Hornet nests, nests in walls and nests up a ladder are worth the pro’s $525 average.
I went through six years of quotes homeowners and renters shared on Reddit. The same job often cost twice as much depending on who came out, attic upsells turned $1,800 jobs into $8,700 ones, and the most common complaint was that it didn’t work.
Usually larvae wandering in from lint or wool nearby, not a mattress infestation, and they don’t bite. Hot-wash bedding and vacuum under the bed; traps cost under $8.
No. In an NC State study, roach bombs didn’t reduce cockroaches at all, while similarly priced gel bait did. Skip the fogger; about $54 of bait, sticky traps and caulk does the job.
Use rat-size snap traps, about $3.59 each: bait with a pea-sized amount, leave them unset for a couple of days, then set them all at right angles to the wall.
Vacuum the car, then set sticky traps and roach bait stations under the seats and in the trunk. Never bomb a car. Supplies run about $36, and a month of empty traps means they’re gone.
A humane mouse trap catches mice alive for $10–30, but it’s only humane if you check it at least every 12 hours and have a plan: released house mice come back or die, and some states ban moving them.
Often, but not always: one mouse can wander in alone. Fresh droppings, flour-patch tracks and 12–24 snap traps (about $14–27) show how many you really have.
Trap along the walls, seal gaps of ¼ inch or more with metal and disinfect droppings, for about $57–71 in supplies. Pro crawl space cleanup runs $200–$4,000.
Set snap traps behind the stove and fridge and under the sink, throw out food in bags or boxes mice could reach, and seal pipe gaps. Traps run about $14; a full kit $57–71.
Most mouse traps fail because of setup: too much bait, a stiff trigger, traps away from the wall, too few traps or easier food nearby. Fix those, then pair traps where droppings are.
