SPI beetles

Carpet Beetle (Anthrenus Verbasci)

The full name is "Variegated Carpet Beetle" which is an accurate description of the colourful white, pale yellow, brown and black scales which produce irregular patches on the outside shell of the insect. The adult beetle is about 1.5–4mm long and is completely harmless. It spends its life in the garden sipping nectar and pollen from flowers.

The adults can fly well and come indoors to lay their eggs on carpets and clothes etc. They are a serious pest in museums where they attack the fur of stuffed animals. One beetle can lay about 100 eggs and these hatch in 10–30 days. The damage is done by larvae that hatch from the eggs.

These larvae spend several months eating any high protein food they can get – carpets, clothes, fur, bird's nests etc. The larvae are very distinctive, being covered in short bristles, giving rise to their common name of "Woolly Bears"

Fur Beetle (Attagenus Pelio)
The Fur Beetle, although a different species, causes similar damage. The adult is about the same size as the Carpet Beetle and also feeds on pollen and nectar from flowers. You will recognise it by the two white spots on its wing cases. The life cycle is almost the same as the Carpet Beetle, with the larvae spending up to 6 months eating carpets, clothes, fur etc. Like the larva of the Carpet Beetle the larva of the Fur Beetle is hairy, but it is much larger and has a long tail of silky hairs.

Treatment and Control
The first signs of an infestation are either seeing the larvae on the floor, or noticing holes appearing in carpets and clothes. Heavily infested material should be removed and destroyed. Infested areas should then be cleaned thoroughly using a hand held vacuum cleaner nozzle, concentrating on cracks and crevices. The vacuum cleaner bag should be removed and destroyed immediately on completion of the work. Infestation often starts from a bird's nest, so if it safe to do so, check lofts and attics to ensure birds are not nesting and remove any old nests.

Beetle Treatment
1/ Our service is to attend and carry out a thorough inspection of your home for Beetle infestation and to treat affected rooms if it is safe to do so. Please note that this may not result in eradication of the insects.

2/ This is a single visit treatment and the products used remain active for many weeks. If the infestation is severe or if our technician so determines, we may supplement this by applying an insecticidal spray, in which case you may need to vacate the property until this dries, which is normally around 2 hours. Our technician will advise you if this is necessary.

3/ We are only permitted to apply insecticides if the pest is confirmed as present, and in rare cases where there are no obvious signs we may instead need lay monitor traps and return to check these to confirm if an infestation is present. The fee for this work is the same as for treatment.
