Preventing pest infestations in long term storage should be a top priority for anyone using a unit from providers like Spyder Moving and Storage CO in Denver. Whether you’re storing extra furniture, seasonal items, or decluttering your home, packing the right way helps keep bugs and rodents out. Denver’s dry weather and cold winters often drive pests indoors, including into storage units. Even clean facilities aren’t immune if items aren’t packed properly. This guide is for Denver residents who want to reduce home clutter by keeping their stuff safe in a storage unit.
Why pests are a risk in Colorado storage units
Colorado’s weather affects how pests behave. When it’s dry, bugs and rodents search for water—even inside storage units. In winter, cold temperatures push them indoors for warmth. Professionals from various moving companies in Denver CO usually recommend sealing items well and checking for gaps. Mice can squeeze through tiny holes, and insects can slip through small cracks. Common pests in Denver storage units include mice, spiders, silverfish, crickets, and wasps. These pests can damage your things by chewing, nesting, or leaving waste. Taking simple steps early helps keep your unit pest-free.
Choose the right storage facility
Where you store your items makes a big difference. Choose a storage facility that looks clean and is well taken care of. Experienced local movers from Denver CO often highlight the importance of asking about pest control. Check if the facility has regular pest inspections and what they do to prevent infestations. Look around—clean hallways and loading areas are a good sign. Some places also offer climate-controlled units, which can help protect your things during extreme weather. A good facility should have clear steps in place to help keep pests out.

Avoid using cardboard boxes for long term storage
Cardboard boxes are cheap and easy to get, but they’re not a good choice for long term storage. They soak up moisture, which can lead to mold and make the box weak over time. Bugs like silverfish feed on cardboard, and mice use it to build nests. Rodents can also chew right through it, which lets them get to your stuff easily. If you’re putting things in storage for a long time, it’s better to use something stronger that doesn’t attract pests and holds up better against moisture and damage.
Use sealed plastic bins for packing
Plastic bins with tight lids work better than cardboard for long term storage. They don’t soak up moisture, and pests like mice can’t chew through them easily. A packing service in Denver would often suggest using clear plastic bins so you can see what’s inside without opening them. Make sure the lid seals tightly all the way around, not just at the corners. A good seal keeps bugs and rodents out. Label each bin so you know what’s in it without having to open everything later and make a mess.
Clean everything before you pack it
Before you pack anything into storage, make sure it’s clean. Dirt, crumbs, pet hair, and smells can bring in pests. Wash all clothes, bedding, and towels. Wipe down furniture with a simple cleaner. Empty out drawers and clean inside them. If you’re storing kitchen items, like toasters or microwaves, check that there’s no food left inside. Even a few crumbs can cause problems later. People doing junk removal in Colorado often find that pests show up where items weren’t cleaned first. Clean items are much safer to store and don’t attract bugs or mice as easily.

Never store food or scented items
Never put food into long term storage, even if it’s sealed or doesn’t spoil. Rodents can smell food from far away and will try to get into anything that smells like it. That includes dry snacks, canned food, and even pet food. It’s also a good idea to leave out things with strong smells, like candles, soap, or air fresheners. Pests might not eat them, but the smell can still attract them. If you’re focused on preventing pest infestations in long term storage, keeping all food and scented items out is a smart and simple step.
Disassemble furniture and wrap it properly
Breaking down beds, tables, and shelves makes them easier to move and takes up less space. Furniture movers from Denver often suggest taking apart large furniture before putting it into storage. It also helps keep pests from hiding in cracks and corners. Instead of using blankets, wrap your furniture in plastic or shrink wrap. Blankets can hold smells and give pests something to nest in. If you use a furniture cover, make sure it’s made for storage and not easy for pests to get through. This helps keep your items cleaner and safer.
Use vacuum-sealed bags for soft goods
Clothing, bedding, and other soft items should be stored in vacuum-sealed bags. These bags remove air, making the items smaller and less likely to attract pests. They also keep bugs and mice out. Vacuum-sealed bags are great for seasonal clothes or large bedding that won’t be used for a while. Before you put the bags into plastic bins, make sure they’re fully sealed. This helps protect your items from pests and saves space in your storage unit. It’s a simple way to keep your things clean and safe.
Seal all boxes and bins tightly
Make sure all packing materials are sealed properly. For cardboard boxes, use strong packing tape to seal every seam on the top and bottom. If you’re using plastic bins, check the lids for any cracks and make sure they snap shut tightly. Bins with rubber seals around the edges provide extra protection. If you’re storing items for a long time, consider taping around the seam of the bin for added security. This helps keep pests out and ensures your items stay safe and secure in storage.

Line the floor of the storage unit
When storing items, keep them off the floor to help with preventing pest infestations in long term storage. Place pallets or thick plastic sheeting on the floor before stacking boxes or bins. This keeps your items raised above the concrete, which can attract moisture or let pests in through small cracks. Even raising items a few inches off the ground helps protect them from temperature changes and makes it easier to check for pests during future visits. This simple step can save your items from moisture and pests over time.
Use natural pest repellents
You don’t need chemicals to keep pests away. Natural repellents like peppermint oil, cedar blocks, and lavender sachets can help. Soak cotton balls in peppermint oil and place them in bins or drawers. Cedar blocks are good for protecting wood furniture or fabric. These natural options are safe for your items and won’t leave behind residue like chemical sprays. They also don’t damage your belongings. Remember to replace or refresh them every few months to keep pests away effectively. It’s a simple, safe way to prevent problems in storage.
Avoid using used packing materials
Using old boxes or secondhand packing materials may seem like a good way to save money, but it’s not worth the risk. Used supplies can carry dirt, moisture, or even insect eggs. You don’t know where they’ve been or what they’ve been exposed to. To avoid pests in your storage unit, always use new, clean packing materials. While it might cost a little more, it’s a small investment that can save you from bigger problems later. It’s better to spend a little extra upfront than deal with pests later.

Inspect everything before it goes in
Before putting anything in your storage unit, inspect it carefully. Look for spider webs, bug droppings, or signs of chewing. Check under cushions and inside drawers. If an item has been stored in a basement or garage, it could have pests inside. Shake out fabrics and wipe down surfaces to be sure. If you find too much clutter or unwanted items, consider using a junk removal service to clear them out. Taking a few extra minutes to inspect each item can prevent pest problems before they start.
Seal gaps and entry points in your storage unit
Even though most storage units are secure, it’s important to check for small openings. Look for cracks in the walls, holes in the corners, or gaps around the door. If allowed by the facility, use weather stripping or foam sealant to close these gaps. A small opening can let in pests, which is why preventing pest infestations in long term storage is very important. Be sure to follow the rules of the storage facility when sealing any gaps. Taking a little time to check for these issues can help avoid pest problems later.
Stacking items strategically will make preventing pest infestations in long term storage easier
How you stack your items in storage matters. Don’t pile everything too high. Leave space between boxes and the walls to help airflow and make pest checks easier. Don’t stack so high that bins could collapse or break—this gives pests a place to hide. Put heavier items on the bottom and avoid blocking the back of the unit. This way, you can access everything easily. Proper stacking helps protect your things and makes it easier to do checks. For those in need of extra help, you can always get moving help in Denver.

Visit the unit regularly
Don’t forget about your storage unit once it’s packed. Make sure to check on it every few months, especially with changing seasons. Look for signs of pests, like droppings, shredded material, or strange smells. If you’re using natural repellents, refresh them during these visits. A quick check helps you spot problems early and avoid bigger damage. Regular visits also allow you to reorganize or check on items that need extra care. This is an important part of preventing pest infestations in long term storage and keeping everything in good condition.
What to do if you spot pests
If you notice signs of pests, tell the facility manager right away. Most storage places have a pest control service they can contact. Take out any affected items and check them carefully. Clean items you can save, and throw away anything that’s too damaged. Repack with better materials and use more secure bins if needed. Don’t ignore even small signs of pests—bugs and rodents can spread fast in storage. Addressing the problem early can help prevent it from getting worse.

Additional tips for seasonal Colorado storage
Colorado’s weather can cause problems for storage. In summer, dryness can make some materials crack, and in winter, cold can bring pests inside. If your items are sensitive to temperature changes, think about using a climate controlled unit. These units keep a steady temperature and humidity level, which helps protect against both pests and moisture. Even in regular units, checking your items every season and making small changes can help keep your belongings safe all year. Taking these steps can prevent damage and make sure your items stay in good condition.
