Why people keep buying it

Quiet. Cordless.
Just works.

01

Silent to humans

15–35 kHz. Above human, dog and cat comfort but right in the deer-alert range. Deer treat it as a persistent threat cue and route around it.

Cordless

03

Roses survived a full season

"Three Crittex around the perimeter of the rose bed. I used to lose every bud overnight in October. Made it through the whole rut with zero browse."

Vegetable garden untouched

"Sweet corn, beans, tomatoes — they cleaned us out by August every year. First year running Crittex and we ate every ear. The neighbor wants to know what we''re doing."

Saved the new orchard

"Planted 12 apple saplings last fall. Two units on the corner posts. Not a single rub or browse all winter — the trees look like they''ve been fenced."

Cheaper than fencing

"Was about to spend $4,000 on 8-foot deer fencing. Crittex stopped them for a fraction of that. Two years later, still working."

Quick answers.

How many do I need?

For garden and orchard use, plan one Crittex per ~5,000 sq ft of protected area. Place units at perimeter corners and along established deer paths. Typical residential gardens use 2–4 units; orchards and acreage use 6+.

How long until deer stop browsing?

Most properties see browsing drop within 7–10 days. Deer learn quickly that the protected area is uncomfortable and route around it. Long-established habits (e.g. a rose bed deer have eaten from for years) can take 2–3 weeks.

Will it work in rain or snow?

Yes. IPX5-rated. Operates through rain, light snow, and freezing temperatures. Battery runtime is reduced in extreme cold.

Does it disturb dogs or cats?

No. Dogs and cats ignore it entirely — Crittex operates above their comfort range and the pulse pattern doesn''t trigger them.

What if it doesn''t work?

30-day money-back guarantee. Email support@crittex-official.com and we''ll refund you. No interrogation.
