Storage facilities are dark and humid and make the perfect home for creepy crawly creatures. If not maintained regularly sooner or later you will find the place infested with insects and rodents. Sometimes even your customers can introduce insects to your facility.
Regularly clean your storage units
This includes the regular spraying with suitable insecticides and fungicides and thoroughly cleaning all the nooks and crannies in the unit before locking it up. Units must always be cleaned immediately before it is rented and after it is returned.
Keep all flower pots away
Do not decorate the facility with flower pots or plants or anything that may attract insects. Try to keep the neatly trimmed gardens as far away as possible from the storage units. If you want to beatify the surroundings with plants then better to do it closer to your front office. Ants tend to make their nests using leaves so you will be giving them a free pass by maintaining a garden close to the facility.
Discourage storage of food items
Unless you specialize in hygienic storage of food do not let your customers keep any food in their personal storage. Apart from food, food crumbs left on furniture or boxes used for packing can attract a host of pests including mice, ants and cockroaches. Ants and cockroaches are disgusting and might not do much damage unless they are left alone for a long time. Comparatively rats and mice can wreak havoc even in a short time. They nibble into wood, cardboard, upholstery and a long list of other things. Having food in just one storage prices in Singapore can attract pests into the entire facility.
You must also take measures to treat bed bugs. They can easily be in some of the furniture stored and remain in the building long after the furniture has been removed. Be especially cautious of the customers that need extra space storage for only a few months every year, like seasonal businessmen. They can inadvertently transport any insects and insect larvae residing in their goods within the facility.
Treating an infestation
There are many methods to do this. Usually the commonly used insecticides made for this purpose would suffice. You might need some specialist advice to deal with fungi though. They are usually persistent and need systematic treatment. A cockroach infestation can usually be treated with boric acid.
The best way to protect from pest infestations is to prevent them. This can be done by sealing up all the cracks and routinely spraying with insecticide. You might not need to do this as often as every month, but once every 3 or 6 months would do depending how prone your unit is to attacks.
