CONSTRAIN
Constrain® – Residual Insecticide for Long-Term Pest Control
Constrain® is a professional, water-based insecticide designed to control a wide range of crawling and flying insects indoors. It is particularly suited to environments where protecting valuable materials, furnishings, fabrics, books and other sensitive items from insect damage is important.
Unlike a treatment designed simply to kill insects that are visible at the time of application, Constrain® provides residual protection on treated surfaces. This makes it useful as part of an ongoing pest management programme, helping to control insects where they hide, rest and breed.
What insects does Constrain® control?
Constrain® can be used against a range of common pest insects, including:
- Clothes moths
- Carpet beetles
- Wood-boring insects
- Biscuit beetles
- Silverfish
- Booklice
- Other flying and crawling insects
This makes it particularly useful in museums, historic properties, archives, libraries, collections, galleries and other buildings where insect damage can be costly or difficult to reverse.
Why use Constrain®?
One of the main advantages of Constrain® is its residual action. Once correctly applied to suitable surfaces, it remains active and can affect insects that subsequently come into contact with the treated area.
Its water-based formulation also makes it suitable for many indoor applications where a conventional solvent-based insecticide may be less desirable.
Used correctly, Constrain® is:
- Water-based
- Non-flammable
- Odourless once dry
- Designed to be non-staining when used according to the instructions
- Suitable for targeted residual treatment
- Effective against both crawling and flying insect pests
How is Constrain® used?
Constrain® should be applied as a targeted surface treatment, concentrating on areas where insects are likely to hide, rest or emerge.
Depending on the pest and environment, these may include:
- Floor edges and skirting boards
- Gaps and cracks
- Under and behind furniture
- Beneath rugs and carpets
- Wardrobes and drawers
- Areas around stored textiles
- Gaps between floorboards
- Other dark, sheltered areas where insects may harbour
Surfaces should be treated evenly and lightly, avoiding unnecessary application to areas that do not require treatment.
Where valuable or delicate objects are involved, items should be assessed before treatment and the product used only in accordance with the relevant instructions.
Constrain® and Integrated Pest Management
Constrain® works particularly well as part of an Integrated Pest Management (IPM) programme.
Rather than relying solely on chemical treatment, IPM combines:
Monitoring → Identification → Prevention → Targeted Treatment → Ongoing Monitoring
For example, insect monitoring traps can be used to establish which pests are present and where activity is occurring. Constrain® can then be used selectively in appropriate harbourage areas, reducing the need for unnecessary treatment throughout an entire building.
This targeted approach is particularly valuable when protecting historic collections, textiles, furniture, books, archives and other irreplaceable materials.
Using Constrain® for moth and beetle control
Clothes moths and carpet beetles can cause significant damage because their larvae feed on natural materials such as wool, fur, feathers and other animal-derived fibres.
Simply killing adult insects does not necessarily solve the problem. Effective control requires attention to the areas where larvae and adults may be hiding.
Constrain® can form part of a wider treatment programme by providing residual protection to suitable surfaces around potential harbourage areas.
Professional residual protection
Constrain® is best considered as part of a long-term pest prevention strategy, rather than simply an insect spray for visible pests.
When combined with good housekeeping, environmental management, monitoring and targeted application, it can help reduce the risk of recurring insect infestations and protect valuable materials from ongoing pest damage.
