Preventions
Small fixes that make a big difference; do these first.
Seal gaps around baseboards, window trim, and pipe penetrations so spiders can’t stroll in.
MONO MONO® SILICONE MAX Premium Sealant 100 ...
Expanding polyurethane foam that seals small openings to block drafts and pest entry points.
The Smart Dispenser gives you controlled, stop-start beads and lets you reuse the can later (keep the dispenser attached and store upright).
Expands to fill gaps up to about 1″ (25 mm), cures rigid, then trims flush in ~1–2 hours; paintable once cured.
Where I use it: around pipe and cable penetrations, along sill plates and rim joists, in basement/garage cracks, and gaps where trim meets framing.
Where not to use: near flues or high heat, in constantly wet areas, or around windows/doors (use the Window & Door low-expansion version for those).
How I apply (quick): 1. Wear gloves/eye protection; lightly mist the gap with water (helps cure). 2. Insert the straw deep in the gap; apply a small bead—it expands. 3. Let cure, then cut/sand flush and paint if desired.
To reuse, leave the Smart Dispenser on, close the valve, and store upright.
Pro tip: Multiple light passes beat one heavy fill—less mess, cleaner finish, better seal against spiders and moth pathways.
GREAT STUFF Gaps & Cracks with Reusable Smart ...
Closes the light gap under exterior doors to stop drafts and pests.
Door Draft Stopper Seal, 2"x39", White
Cut-to-fit fiberglass mesh for repairing or building standard window and door screens.
The black finish improves outward visibility, and fiberglass won’t crease or dent like aluminum, so it stays tidy after bumps. Sized to cover most single windows or a full door panel (or multiple small repairs), with enough overhang to get a tight, w...
Works with most common screen frames and spline channels.
Where I use it: window frames with torn mesh, sliding door panels, and basement/hall windows that need better bug control without blocking airflow.
Install (quick): 1. Remove the frame; pull out old spline and screen. 2. Lay the new mesh with ~2" overhang on all sides. 3. Roll new or existing spline into the channel with a screen tool, starting on the long side and keeping the mesh taut. 4. Trim excess with a sharp utility knife; reinstall the frame.
Pro tips: Don’t overstretch—light, even tension prevents waves. If your frame’s channel is shallow, choose a slightly smaller spline; for loose fits, go one size up. Warm mesh lays flatter and is easier to work with.
Everbilt 36-inch W x 84-inch H Fiberglass Window and ...
Clear, stackable canisters with a one-press pop lid that seals tight to keep pantry staples fresh and odors out.
Perfect for cereal, flour, sugar, oats, rice, beans, and snacks, and the squared corners pour cleanly into measuring cups without mess.
The pop-top makes one-hand use easy while you cook; the gasket lifts out for a quick rinse so lids stay squeaky clean.
Why I like them for prevention: decanting dry goods into true airtight containers helps block pantry pests and lets you spot issues at a glance—no more half-open bags attracting visitors.
How I use them: - Tall canister for cereals/pasta; medium for flour, oats, rice, and baking sugar. - Label the item + purchase date on the side; first-in, first-out. - For bulk grains/flour, freeze 72 hours in the original bag first, then transfer to these containers.
Pro tips: Don’t overfill—leave 1–2 cm headroom for a perfect seal. Wash lids by hand to protect the mechanism; bins are top-rack dishwasher safe. Stack with heavier items on the bottom to keep shelves tidy and stable.
Airtight Pop-Top Food Storage Containers, 2-Piece
Clear, countertop-worthy storage that actually seals. Each 88-oz jar (about 2.6 L) holds big-bag staples—flour, sugar, rice, pasta, cereal, cookies—and the airtight lid with gasket helps lock out moisture and pantry pests while keeping aromas in.
Wide mouths make scooping and cleaning easy, and the included labels keep shelves organized at a glance.
Why it’s in Prevention: moving dry goods from opened bags into airtight glass lets you see contents, spot issues early, and remove the paper/box hiding spots that attract pantry visitors.
How I use them: - One jar per staple; write the item + purchase date on the label for first-in/first-out rotation. - For bulk grains/flour, freeze 72 hours in the original bag first, then transfer to the jar.
Hand-wash lids to preserve the seal; jars are easy to rinse and dry before refilling.
Fit notes: 88 oz typically fits a standard 2 kg bag of flour or ~2 kg of rice (leave a little headroom for an easy close).

Monitoring
Reduce and track activity without chemicals.
Low-profile glue boards that catch wandering spiders and other crawling bugs while helping you monitor where activity is highest.
Pre-baited adhesive draws pests in; fold into a tent to keep dust off the glue and fingers/paws out, or leave flat to slide under appliances and furniture.
Where to place: along baseboards and wall edges, behind furniture, near door thresholds, under sinks/vanities, basement corners, and along garage walls. Focus on paths you’ve seen spiders travel or where webs keep reappearing.
Set up (quick): 1. Peel liner and fold on the score lines to make a tent (or use flat). 2. Place sticky side down, parallel to walls (bugs follow edges). 3. Use a marker to note the date/location on each trap. 4. Monitoring & maintenance: check weekly; replace every 2–4 weeks or sooner if dusty or full. 5. Log “hot spots” so you can seal entry points and target cleaning there.
Disposal & safety: fold closed and toss in household trash.
Keep out of reach of children and pets; avoid high-moisture areas where glue can lose tack.
Pro tip: Use a grid approach (one trap about every 10–15 feet in problem rooms) for two weeks, then consolidate more traps in the areas that catch the most—this tightens your prevention plan fast.
Spider Traps Indoor (16) - Sticky Insect Glue
Low-profile, non-toxic sticky traps that lure adult webbing clothes moths (the sweater-eaters) to help you monitor and reduce activity in closets and storage areas.
The boosted pheromone pad draws in males, interrupting the breeding cycle so you can protect wool, cashmere, and other natural fibers.
Where to place: hang or set at closet corners, under hanging garments, near baseboards, and inside storage cabinets—about waist height. Avoid open windows/vents (airflow weakens the lure).
Use 1–2 traps per small closet; larger rooms may need more.
Set up (quick): 1. Open sealed lure and peel the liner to expose glue. 2. Fold into a tent (keeps dust off) or hang using the tab if provided. 3. Write the date/location on the trap for easy tracking. 4. Monitoring & maintenance: check weekly and replace every 6–8 weeks or sooner if full/dusty.
Traps are for detection and population knockdown—pair with garment cleaning, sealed storage bags/boxes, and a quick closet vacuum to address larvae.
Disposal & safety: fold closed and discard with household trash. Keep out of reach of children and pets; avoid contact with fabrics and finished surfaces.
Pro tip: Run a before/after sweep—deploy traps for two weeks, note the hot spots, then deep-clean and store vulnerable items; redeploy fresh traps to confirm the drop in catches.
BUFFALLOW Pantry Moth Traps Pack of 8 - Glue Traps
Natural cedar pieces that add a fresh, clean scent and help discourage clothes-moth activity around wool, cashmere, and stored fabrics.
The mixed set (blocks, chips, balls, sachets) lets you cover hanging spaces, shelves, bins, and drawers without taking up room.
Where to place: * Closets: hang or tuck blocks near shoulders of wool coats; drop balls on shelves; place sachets in storage bins. * Drawers: a sachet or a few chips per drawer. Storage boxes/garment bags: one sachet per container.
How to use (quick): 1. Distribute pieces evenly—don’t overstuff one area. 2. Keep direct contact off delicate/light fabrics to prevent possible oil transfer (use sachets or a small cloth barrier). 3. Combine with clothes-moth traps (for monitoring) and clean storage to address the full life cycle.
Refresh & maintenance: When the scent fades, lightly sand blocks/balls (a few strokes with fine sandpaper) or give chips a gentle shake to expose new surface.
Optionally add 1–2 drops of cedarwood oil to a sachet (not directly on garments).
Replace or rotate pieces every few months during peak season.
Pro tip: After laundering or a short warm-dryer cycle (check care labels), store woolens in sealed bags/boxes with a sachet inside; use pheromone traps in the closet to verify activity is trending down.

Dusts & Sprays
Apply precisely where pests travel or hide; follow labels closely.
Ready-to-use aerosol for spot and crack-and-crevice applications where spiders travel and hide.
Delivers fast knockdown on contact and lets you lay a light barrier along baseboards, door thresholds, window frames, corners, and garage/basement edges.
How I apply (quick): 1. Prep: Remove webs, crack a window, keep people/pets out of the room. 2. Cover aquariums; avoid food surfaces and fabrics. 3. Targeted spray: Hold can ~30–45 cm away. Use short, even bursts along edges and into gaps (under sinks, around plumbing, behind appliances).
Dry time: Let fully dry before re-entry; wipe any overspray from hard floors.
Exterior option: Light band around the foundation, door frames, and under eaves (avoid runoff and windy days).
Good for: corners and sill plates, utility rooms, garages, and exterior entry points.
Avoid: bedding, toys, pet areas, and plants. Always follow label directions.
Pro tip: Pair with monitoring traps to see where activity persists, then re-treat only those hot spots—less product, better results.
Wilson SPIDER OUTTM Aerosol Spider Killer, 425 g
Indoor/Outdoor — Contact-kill aerosol for spiders, silverfish, bed bugs, and other crawling insects.
Designed for spot and crack-and-crevice treatments, it lays an even band along travel paths (baseboards, door thresholds, window frames) and reaches tight gaps under sinks and behind appliances.
How I apply (quick): 1. Prep: Remove webs, ventilate, keep kids/pets out. 2. Cover aquariums; keep away from food and fabrics. 3. Targeted spray: Hold can ~30–45 cm from surface; use short, controlled bursts along edges, corners, and entry points. 4. Let dry fully before re-entry; wipe any overspray from hard floors to prevent slick spots.
Exterior use: Light perimeter band around door frames, garage thresholds, and under eaves on a calm, dry day.
Good for: basements, utility rooms, garages, and exterior entry points where spiders roam.
Avoid: toys, bedding, pet areas, and plants. Always follow the label.
Pro tip: Pair with sticky monitoring traps to map hot spots—treat only where catches persist for a tighter, lower-use routine.
