Festive decorations are often stored for months in cupboards, lofts, boxes and other less frequently accessed areas. During this time, insects or rodents can find shelter among cardboard, paper, fabric and other stored materials, particularly where there is moisture or little disturbance.
Before bringing these decorations back into your home, a quick inspection can help identify pest activity, moisture damage and contamination before the items are displayed.
Stored decorations can become vulnerable to pests when they provide shelter, undisturbed spaces or suitable environmental conditions.
Cardboard and paper boxes can provide hiding places for cockroaches and other insects, while damp storage conditions can favour pests such as booklice and silverfish. Food residue on stored items or nearby surfaces can also attract ants and other pests.
The risk is generally higher when decorations are stored for long periods without being checked.
| Pest | Why it may be associated with stored decorations | Signs to look for |
|---|---|---|
| Cockroaches | Cardboard, paper and undisturbed storage | Droppings, egg cases, shed skins or live insects |
| Silverfish | Paper, cardboard and humid conditions | Live insects, shed skins or material damage |
| Booklice | Damp, warm and humid storage | Small insects, moisture or mould |
| Ants | Food residue or nearby entry points | Live ants, trails or entry points |
| Rodents | Stored materials can provide shelter or nesting material | Droppings, gnaw marks or shredded material |
Cockroaches can be associated with cardboard boxes and other stored materials. University of Minnesota Extension's guidance on cockroaches provides further information on their association with household storage materials.
Booklice are associated with damp conditions, making moisture control particularly relevant when inspecting stored paper and cardboard items.
Instead of inspecting every material separately, use the following sequence to check both the decorations and their storage environment.
| Step | What to check | What to look for |
|---|---|---|
| 1. Inspect the container | Examine the outside before opening it | Holes, droppings, gnaw marks, webbing, insects, moisture stains or mould |
| 2. Open carefully | Open the container without immediately spreading the contents around the room | Visible insects, unusual odours, droppings or other evidence |
| 3. Inspect decorations individually | Check folds, seams, joints, edges and concealed areas | Holes, staining, shed skins, webbing, insects or material damage |
| 4. Check different materials | Pay particular attention to cardboard, paper, fabric, wood and electrical decorations | Moisture damage, small holes, gnaw marks, damaged insulation or contamination |
| 5. Check for moisture | Examine the decorations, container and surrounding storage area | Damp cardboard, mould, water stains, softened paper or musty odours |
| 6. Inspect the empty container | Check the bottom, corners, folds and seams after removing the decorations | Droppings, egg cases, shed skins, dead insects or other evidence |
If you find evidence in the container but not on the decorations, the storage environment itself may require further investigation.
The appropriate response depends on the evidence and whether the activity appears isolated or recurring.
| Finding | What it may indicate | Recommended response |
|---|---|---|
| Dust or minor dirt only | Normal storage contamination | Clean the decoration appropriately before reuse |
| One dead insect with no other evidence | Possible incidental entry | Remove it and inspect the container and surrounding area |
| Droppings, egg cases or shed skins | Previous or ongoing pest activity | Separate the affected item and inspect the remaining contents |
| Multiple live pests | Possible active infestation | Identify the pest and assess the extent of activity |
| Gnaw marks or nesting material | Possible rodent activity | Inspect other stored items and surrounding entry points |
| Repeated material damage | Continuing pest activity or unsuitable conditions | Investigate the storage environment and possible source |
| Dampness or mould | Moisture-related environmental issue | Address the moisture source and improve ventilation |
| Evidence across several containers | Possible wider infestation | Inspect the broader storage area and consider professional assessment |
| Activity returns after cleaning | Unresolved harbourage, entry point or environmental condition | Trace and address the underlying source |
Cleaning can remove dirt and some physical evidence, but it does not necessarily eliminate an infestation. The U.S. EPA's Integrated Pest Management principles emphasise identifying and monitoring pest activity, addressing conditions that support it, and selecting appropriate control measures based on the situation.
The decision should depend on the type of material, extent of damage and level of contamination.
| Condition | Consideration |
|---|---|
| Minor surface contamination | Clean appropriately for the material and inspect again |
| Washable fabric with limited contamination | Clean thoroughly before reuse |
| Minor damage with no ongoing activity | Assess whether the item can be safely restored |
| Extensive contamination | Consider whether the item can be effectively cleaned |
| Severe structural or material damage | Replacement may be more practical |
| Repeated pest activity associated with the item | Investigate the storage environment before returning it to storage |
Pest prevention should begin before decorations are packed away.
| Storage practice | Why it matters |
|---|---|
| Clean decorations before storage | Removes food, oil, plant material and other residues that may attract pests |
| Dry items completely | Reduces moisture that can contribute to mould and support moisture-associated pests |
| Use suitable containers | Intact, closable containers can reduce access and make inspection easier |
| Reduce unnecessary cardboard and clutter | Limits potential shelter and concealed spaces |
| Keep storage areas accessible | Makes future inspection easier and helps prevent pest evidence from going unnoticed |
| Address cracks and openings | Reduces potential pest entry routes |
| Control moisture | Repair leaks, improve ventilation and address persistent dampness |
| Monitor periodically | Helps identify pest activity before it becomes more extensive |
For moisture-related pest concerns, UC IPM's silverfish and firebrat guidance recommends keeping susceptible areas clean and dry, addressing leaks and reducing suitable hiding places.
Sometimes pest activity is a symptom of a larger issue, such as an entry point, moisture problem, hidden harbourage or an infestation inside a wall, cupboard or storage area.
A professional pest inspection can help identify where pests are entering or hiding and determine the appropriate treatment based on the type and extent of infestation.
Festive cleaning is about more than making your home look beautiful. It's also a good opportunity to check the less visible corners where pests may be hiding.
If you notice recurring pest activity around storage areas, kitchens, cupboards or other parts of your home, Rentokil PCI can help assess the situation and recommend an appropriate pest management solution.
Because when you're bringing out the decorations, the only surprises you want are the festive kind.
Yes. Undisturbed storage boxes can provide shelter for insects and rodents. The likelihood of pest activity depends on the materials stored, moisture levels, access to food and the surrounding storage conditions.
Look for droppings, egg cases, shed skins, webbing, small holes, gnaw marks, dead insects and damaged materials. Dampness, mould or unusual odours may also indicate a storage issue that needs attention.
Avoid applying pest-control products directly to decorations unless the product label specifically permits that use. Instead, separate affected items, inspect the storage area and follow appropriate cleaning guidance for each material. Seek professional advice if pest activity persists.
Yes. Folds, seams, joints, packaging and gaps around decorative items can provide hiding places. Inspect fabric and artificial flowers carefully, and check electrical decorations for damaged insulation or signs of contamination before use.
Intact, closable plastic containers can reduce pest access compared with damaged or loosely sealed cardboard boxes. However, decorations should be clean and completely dry before storage, and the containers should be checked periodically.
Consider a professional inspection if you find multiple live pests, droppings or gnaw marks across several boxes, repeated material damage, or pest activity that returns after cleaning. These signs may indicate a wider infestation or an unresolved entry point.
