Every autumn homes around the country gets flooded with Spiders, moving in from the garden in search for a mate. Primrose recommends ultrasonic repellers as the most effective device to keep your house Spider free, which work by upsetting a spider’s sense of “hearing”, forcing them to move to new areas.

Ultrasonic Repellers

Although spiders have no formal hearing, they have tiny hairs, called trichobothria, which respond to vibrations (sound). These hairs play an important role in hunting as they allow spiders to detect an object’s direction of travel and size, alerting it to prey. It is likely ultrasound disturbs this important function, causing spiders to seek different hunting grounds.

At Primrose, we have developed an especially devious device to rid your house of spiders – our Whole House Advanced Spider Repeller, which can be adjusted to emit variable frequencies at random intervals to cause maximum confusion. It also emits electromagnetic waves, which is believed to upset spiders’ magnetoreception, affecting their ability to navigate.

We also stock a battery powered model which is perfect for outbuildings.

Why ultrasound?

Ultrasound is perfect as by definition, the frequencies are higher than the upper audible limit of human hearing, so there is no inconvenience. It is also detectable by a large range of pests and will help keep rats out of your house. Importantly, unlike other solutions, ultrasonic devices are a permanent solution to your spider problem. You can spray and catch as many spiders as you wish, but providing there is no deterrent, they will return.

Why Primrose?

Primrose sells thousands of units each year with less than 2% returned as ineffective. Our top selling model has over 900 independently verified reviews with an average rating of 4/5 and has a money back guarantee.

Spider Catchers

Primrose stocks three types of spider catchers powered by different mechanisms. One is powered by a lever that closes bristles around a spider, another sucks a spider in a vacuum and the last traps a spider in a compartment. All are humane, allowing you to release the captured spider in a suitable location. If you are decided on a spider catcher, the first two models are the best. The latter is only suitable for flat surfaces. Of the first two models, the vacuum allows you to capture multiple spiders, the downfall is that it requires batteries.

Spider Sprays

Our spider spray is designed to stop spiders building cobwebs for up to 4 weeks. Simply spray on affected areas.
